    Neurodevelopmental disorders, including autism spectrum disorder (ASD), arise from complex interactions between genetic and environmental factors. Maternal immune activation (MIA) is a key environmental risk factor that disrupts embryonic neurodevelopment, primarily through inflammatory cytokines. However, the contribution of non-inflammatory cytokines, particularly hematopoietic growth factors, remains poorly understood. Here, we identified granulocyte colony-stimulating factor (G-CSF) as a candidate mediator of MIA-induced neurodevelopmental alterations. Polyinosinic:polycytidylic acid [poly(I:C)] administration to pregnant dams at embryonic day 12.5 (E12.5) significantly increased G-CSF levels in both maternal plasma and embryonic tissue. To assess its contribution to neurodevelopmental alterations, we administered human G-CSF (hG-CSF) to pregnant dams at E12.5. At the structural level, male offspring exposed to prenatal hG-CSF showed increased dendritic spine density and a higher proportion of immature spines in the medial prefrontal cortex. Behaviorally, both male and female offspring exhibited altered social preference. Bulk RNA-seq analysis of the prefrontal cortex revealed altered enrichment of pathways related to synapse organization, translation, and mitochondrial function in both sexes, with opposite directions of enrichment in males and females. In vitro, G-CSF attenuated synapse maturation and enhanced microglial phagocytic activity. These findings suggest that G-CSF may contribute to MIA-associated neurodevelopmental alterations, potentially through disrupted synapse maturation and microglial function. Our results highlight a hematopoietic pathway that may contribute to mechanisms underlying neurodevelopmental disorders, including ASD.

    Abstract Maternal perinatal depression (MPD) is associated with reduced maternal plasma oxytocin (OXT) levels and an increased risk of autism spectrum disorder (ASD) in offspring. Using data from 23,218 Japanese mother–child pairs, we evaluated the relationship between MPD—assessed with the Kessler Psychological Distress Scale (K6) and the Edinburgh Postnatal Depression Scale (EPDS)—and autistic-related traits (ART) in toddlers, measured by the Tokyo Autistic Behavior Scale (TABS). We also tested the potential causal relationship of maternal stress exposure on OXT, its receptor (OXTR), and offspring outcomes using a prenatal stress-exposed mouse model. In the human cohort study, higher K6 or EPDS scores during pregnancy and postpartum were significantly associated with increased TABS scores in toddlers. Offspring of mothers with MPD (K6 or EPDS score ≥ 9) during pregnancy or postpartum exhibited a higher risk of ART (TABS score ≥ 15; P  < 0.05). This risk was particularly pronounced in female toddlers exposed to MPD during pregnancy and postpartum (ORs: 5.805–9.367; P  < 0.05). Female toddlers born to mothers with MPD also had lower birth weight, and their ART were positively correlated with K6 scores during mid-gestation and with impaired maternal bonding postpartum. In the mouse model, chronically stressed dams displayed depressive-like behaviors, and their female juveniles exhibited increased self-grooming and impaired social interaction. Furthermore, OXTR mRNA levels were significantly reduced in the prefrontal cortex of female juveniles from stressed dams. These findings suggest that MPD increases the risk of ART, particularly in females, highlighting potential sex-specific mechanisms underlying ASD susceptibility.

    Fatty acid-binding protein 4 (FABP4), a key regulator of lipid metabolism and inflammation, has been implicated in neurodevelopmental disorders, including autism spectrum disorder (ASD). This study investigated the effects of FABP4 inhibition during gestation and lactation on offspring neurodevelopment using the selective FABP4 inhibitor BMS309403. Female mice received BMS309403 (15 mg/kg) via oral gavage from two weeks before mating to postnatal day 28 (P28). Administration of BMS309403 to mouse dams resulted in autism-like phenotypes in male offspring (behavioral tests: n = 7-10 per group; spine analysis: 6 mice per group, n = 26-38 dendrites per group), characterized by increased dendritic spine density in the prefrontal cortex, impaired vocal communication, increased repetitive behaviors, and depression-like symptoms. Fatty acid analysis (n = 4-6 per group) revealed significant alterations in maternal and fetal lipid profiles, including elevated arachidonic acid levels in maternal plasma and increased n6PUFAs in the fetal brain, suggesting a pro-inflammatory lipid environment. Principal component analysis demonstrated distinct clustering of lipid profiles between control and BMS309403-treated groups. Cytokine analysis (n = 6 per group) indicated reductions in IL-10 and IL-12(p40) in maternal plasma and decreased TNFα in the fetal plasma, suggesting dysregulation in systemic inflammatory signaling. These findings suggest that FABP4 inhibition during the perinatal period perturbs lipid metabolism and may influence neurodevelopment through systemic metabolic changes. Although the direct effects of BMS309403 on the fetal brain cannot be excluded, alteration in maternal metabolism and placental function may have contributed to the observed neurodevelopmental changes in offspring.

    AIM: Genome-wide association studies (GWAS) of postpartum depression (PPD) based on accumulated cohorts with multiple ethnic backgrounds have failed to identify significantly associated loci. Herein, we conducted a GWAS of Japanese perinatal women along with detailed confounding information to uncover PPD-associated loci. METHODS: The first and second cohorts (n = 9260 and n = 8582 perinatal women enrolled in the Tohoku Medical Megabank Project) and the third cohort (n = 997), recruited at Nagoya University, underwent genotyping. Of them, 1421, 1264, and 225 were classified as PPD based on the Edinburgh Postnatal Depression Scale 1 month after delivery. The most influential confounding factors of genetic liability to PPD were selected, and logistic regression analyses were performed to evaluate genetic associations with PPD after adjusting for confounders. RESULTS: A meta-analysis of GWAS results from the three cohorts identified significant associations between PPD and the following loci (P < 5 × 10-8) by integrating the number of deliveries and the number of family members living together as the most influential confounders: rs377546683 at DAB1, rs11940752 near UGT8, rs141172317, rs117928019, rs76631412, rs118131805 at DOCK2, rs188907279 near ZNF572, rs504378, rs690150, rs491868, rs689917, rs474978, rs690118, rs690253 near DIRAS2, rs1435984417 at ZNF618, rs57705782 near PTPRM, and rs185293917 near PDGFB. Pathway analyses indicated that SNPs suggestively associated with PPD were mostly over-represented in categories including long-term depression, GnRH signaling, glutamatergic synapse, oxytocin signaling, and Rap1 signaling. CONCLUSION: The current GWAS study identified eight loci significantly associated with PPD, which may clarify the genetic structure underlying its pathogenesis.

    Abstract Objective The objective of this study was to investigate the inter-relationships among genetic risk, adherence to a healthy lifestyle, and susceptibility to hyperuricaemia. Methods This prospective cohort study was conducted with 7241 hyperuricaemia-free individuals aged ≥20 years from the Tohoku Medical Megabank Community–based cohort study. A comprehensive lifestyle score included assessment of BMI, smoking, drinking, and physical activity, and a polygenic risk score (PRS) was constructed based on uric acid loci from a previous genome-wide association study meta-analysis. A multiple logistic regression model was used to estimate the association between genetic risk, adherence to a healthy lifestyle, and hyperuricaemia incidence and to calculate the area under the receiver operating characteristic curve (AUROC). Hyperuricaemia was defined as a uric acid level of ≥7.0 mg/dL or a self-reported history of hyperuricaemia. Results Of the 7241 adults [80.7% females; mean (±s.d.) age: 57.7 (12.6) years], 217 (3.0%) developed hyperuricaemia during 3.5 years of follow-up period. Genetic risk was correlated with hyperuricaemia development (P for interaction = 0.287), and lifestyle risks were independently associated. Participants with a high genetic risk and poor lifestyle had the highest risk (odds ratio: 5.34; 95% CI: 2.61–12.10). Although not statistically significant, adding the PRS in the model with lifestyle information improved predictive ability (AUROC = 0.771, 95% CI: 0.736–0.806 for lifestyle; AUROC = 0.785, 95% CI: 0.751–0.819 for lifestyle and PRS; P= 0.07). Conclusion A healthy lifestyle to prevent hyperuricaemia, irrespective of genetic risk, may mitigate the genetic risk. Genetic risk may complement lifestyle factors in identifying individuals at a heightened hyperuricaemia risk.

    Suicide is a major public health priority, and its molecular mechanisms appear to be related to glial abnormalities and specific transcriptional changes. This study aimed to identify and synthesize evidence of the relationship between glial dysfunction and suicidal behavior to understand the neurobiology of suicide. As of 26 January 2024, 46 articles that met the inclusion criteria were identified by searching PubMed and ISI Web of Science. Most postmortem studies, including 30 brain regions, have determined no density or number of total Nissl-glial cell changes in suicidal patients with major psychiatric disorders. There were 17 astrocytic, 14 microglial, and 9 oligodendroglial studies using specific markers of each glial cell and further on their specific gene expression. Those studies suggest that astrocytic and oligodendroglial cells lost but activated microglia in suicides with affective disorder, bipolar disorders, major depression disorders, or schizophrenia in comparison with non-suicided patients and non-psychiatric controls. Although the data from previous studies remain complex and cannot fully explain the effects of glial cell dysfunction related to suicidal behaviors, they provide risk directions potentially leading to suicide prevention.

    Background Evaluating and controlling confounders are necessary when investigating molecular pathogenesis using human postmortem brain tissue. Particularly, tissue pH and RNA integrity number (RIN) are valuable indicators for controlling confounders. However, the influences of these indicators on the expression of each gene in postmortem brain have not been fully investigated. Therefore, we aimed to assess these effects on gene expressions of human brain samples. Methods We isolated total RNA from occipital lobes of 13 patients with schizophrenia and measured the RIN and tissue pH. Gene expression was analyzed and gene sets affected by tissue pH and RIN were identified. Moreover, we examined the functions of these genes by enrichment analysis and upstream regulator analysis. Results We identified 2,043 genes (24.7%) whose expressions were highly correlated with pH; 3,004 genes (36.3%) whose expressions were highly correlated with RIN; and 1,293 genes (15.6%) whose expressions were highly correlated with both pH and RIN. Genes commonly affected by tissue pH and RIN were highly associated with energy production and the immune system. In addition, genes uniquely affected by tissue pH were highly associated with the cell cycle, whereas those uniquely affected by RIN were highly associated with RNA processing. Conclusion The current study elucidated the influence of pH and RIN on gene expression profiling and identified gene sets whose expressions were affected by tissue pH or RIN. These findings would be helpful in the control of confounders for future postmortem brain studies.

    Introduction Perinatal women tend to have difficulties with sleep along with autonomic characteristics. This study aimed to identify a machine learning algorithm capable of achieving high accuracy in predicting sleep–wake conditions and differentiating between the wake conditions before and after sleep during pregnancy based on heart rate variability (HRV). Methods Nine HRV indicators (features) and sleep–wake conditions of 154 pregnant women were measured for 1 week, from the 23rd to the 32nd weeks of pregnancy. Ten machine learning and three deep learning methods were applied to predict three types of sleep–wake conditions (wake, shallow sleep, and deep sleep). In addition, the prediction of four conditions, in which the wake conditions before and after sleep were differentiated—shallow sleep, deep sleep, and the two types of wake conditions—was also tested. Results and Discussion In the test for predicting three types of sleep–wake conditions, most of the algorithms, except for Naïve Bayes, showed higher areas under the curve (AUCs; 0.82–0.88) and accuracy (0.78–0.81). The test using four types of sleep–wake conditions with differentiation between the wake conditions before and after sleep also resulted in successful prediction by the gated recurrent unit with the highest AUC (0.86) and accuracy (0.79). Among the nine features, seven made major contributions to predicting sleep–wake conditions. Among the seven features, “the number of interval differences of successive RR intervals greater than 50 ms (NN50)” and “the proportion dividing NN50 by the total number of RR intervals (pNN50)” were useful to predict sleep–wake conditions unique to pregnancy. These findings suggest alterations in the vagal tone system specific to pregnancy.

    AIM: Previous studies based on a relatively limited number of subjects have indicated potential associations between plasma cytokine concentrations in perinatal women and postpartum depression (PPD). This report aimed to examine alterations in cytokine levels during pregnancy and after delivery by measuring nine cytokines in prenatal and postnatal plasma samples in a large cohort. METHODS: A nested, case-control study was conducted using plasma samples from 247 women with PPD (Edinburgh Postnatal Depression Scale: EPDS ≥9) and 243 age-matched control (EPDS ≤2) women from among perinatal women who participated in the Tohoku Medical Megabank three-generation cohort. Concentrations of nine plasma cytokines (IFN-γ, IL-1β, IL-4, IL-6, IL-10, IL-12p40, IL-12p70, IL-13, and TNF-α) in plasma collected at the time of enrollment during pregnancy and one month after delivery were determined using an immunoassay kit. RESULTS: Cross-sectional comparisons of cytokine levels during pregnancy and after delivery indicated that the PPD group maintained significantly lower plasma IL-4 levels during pregnancy and after delivery than the control group, and that plasma IL-4 levels decreased significantly during pregnancy regardless of PPD status. Plasma IL-10 levels were significantly higher during pregnancy than after delivery only among healthy controls, and plasma IL-10 levels were significantly higher in the control group than in the PPD group. Moreover, IFN-γ, IL-6, IL-12p40, and TNF-α levels were significantly lower during pregnancy compared with after delivery regardless of PPD status. CONCLUSIONS AND RELEVANCE: These results suggest a potential protective effect of the anti-inflammatory cytokines IL-4 and IL-10 during pregnancy against the development of PPD.

    N-acetylcysteine (NAC) is an antioxidant that prevents tumor necrosis factor (TNF)-α-induced cell death, but it also acts as a pro-oxidant, promoting reactive oxygen species independent apoptosis. Although there is plausible preclinical evidence for the use of NAC in the treatment of psychiatric disorders, deleterious side effects are still of concern. Microglia, key innate immune cells in the brain, play an important role in inflammation in psychiatric disorders. This study aimed to investigate the beneficial and deleterious effects of NAC on microglia and stress-induced behavior abnormalities in mice, and its association with microglial TNF-α and nitric oxide (NO) production. The microglial cell line MG6 was stimulated by Escherichia coli lipopolysaccharide (LPS) using NAC at varying concentrations for 24 h. NAC inhibited LPS-induced TNF-α and NO synthesis, whereas high concentrations (≥30 mM) caused MG6 mortality. Intraperitoneal injections of NAC did not ameliorate stress-induced behavioral abnormalities in mice, but high-doses induced microglial mortality. Furthermore, NAC-induced mortality was alleviated in microglial TNF-α-deficient mice and human primary M2 microglia. Our findings provide ample evidence for the use of NAC as a modulating agent of inflammation in the brain. The risk of side effects from NAC on TNF-α remains unclear and merits further mechanistic investigations.

    Examining plasma metabolic profiling during pregnancy and postpartum could help clinicians understand the risk factors for postpartum depression (PPD) development. This analysis targeted paired plasma metabolites in mid-late gestational and 1 month postpartum periods in women with (n = 209) or without (n = 222) PPD. Gas chromatogram-mass spectrometry was used to analyze plasma metabolites at these two time points. Among the 170 objected plasma metabolites, principal component analysis distinguished pregnancy and postpartum metabolites but failed to discriminate women with and without PPD. Compared to women without PPD, those with PPD exhibited 37 metabolites with disparate changes during pregnancy and the 1-month postpartum period and an enriched citrate cycle. Machine learning and multivariate statistical analysis identified two or three compounds that could be potential biomarkers for PPD prediction during pregnancy. Our findings suggest metabolic disturbances in women with depression and may help to elucidate metabolic processes associated with PPD development.

    Microglia have been suggested to be involved in the underlying mechanism of conditional fear memory formation by regulating inflammatory cytokines. However, the mechanism linking microglia and neuronal activity related to fear conditioning remains unclear. This study characterized the transcription profile of microglia in a fear memory conditional mouse model. Compared with those in control mice microglia, the most significantly induced genes were synapse-related, whereas immune-related genes were reduced due to fear memory consolidation. Whilst the increased expression of synapse-related genes was reversed after fear memory extinction, that of immunological genes was not, strongly suggesting a connection between microglia, neurons, and a dysregulated immune response following contextual fear conditioning. Furthermore, in the hippocampal microglia, we found that the expression of neurotransmitter release regulators, γ-aminobutyric acid (GABA) receptor GABRB3 and synapsin 1/2, increased under fear memory consolidation and restored (decreased) after extinction. In addition, compared with the transcription profile in peripheral monocytes, few overlapping genes were not enriched in biological processes. Taken together, the identified conditional fear stress-induced changes in mouse microglial transcription profiles suggest that microglia-neuron communication mediates contextual fear conditioning.

    BACKGROUND: Oxytocin is a neuropeptide synthesized in the hypothalamus. In addition to its role in parturition and lactation, oxytocin mediates social behavior and pair bonding. The possibility of using oxytocin to modify behavior in neurodevelopmental disorders, such as autism spectrum disorder, is of clinical interest. Microglia are tissue-resident macrophages with roles in neurogenesis, synapse pruning, and immunological mediation of brain homeostasis. Recently, oxytocin was found to attenuate microglial secretion of proinflammatory cytokines, but the source of this oxytocin was not established. This prompted us to investigate whether microglia themselves were the source. METHODS: We examined oxytocin expression in human and murine brain tissue in both sexes using immunohistochemistry. Oxytocin mRNA expression and secretion were examined in isolated murine microglia from wild type and oxytocin-knockout mice. Also, secretion of oxytocin and cytokines was measured in cultured microglia (MG6) stimulated with lipopolysaccharide (LPS). RESULTS: We identified oxytocin expression in microglia of human brain tissue, cultured microglia (MG6), and primary murine microglia. Furthermore, LPS stimulation increased oxytocin mRNA expression in primary murine microglia and MG6 cells, and oxytocin secretion as well. A positive correlation between oxytocin and IL-1β, IL-10 secretion emerged, respectively. CONCLUSION: This may be the first demonstration of oxytocin expression in microglia. Functionally, oxytocin might regulate inflammatory cytokine release from microglia in a paracrine/autocrine manner.

    One of the major properties of microglia is to secrete cytokines as a reaction to stress such as lipopolysaccharide (LPS) application. The mechanism of cytokine secretion from the microglia upon stress through the inflammasome-mediated release process is well studied, and the voltage-gated Kv1.3 channel is known to play an important role in this process. Most previous studies investigated long-term inflammasome-mediated cytokine release (at least over 4 h) and there are only a few studies on the acute reaction (within minutes order) of the microglia to stress and its cytokine secretion capacity. In this study, we found that LPS induced an increase in Kir2.1 current within 15 min after administration but had no effect on voltage-dependent outward currents. Moreover, cytological and western blot analysis revealed that the increase in the Kir2.1 channel current after LPS administration was induced by the translocation of Kir2.1 from the cytoplasm to the cell surface. From an experiment using the inhibitor and trafficking mutation of Kir2.1, an increase in Kir2.1 was found to contribute to the secretion of the inflammatory cytokine, IL-1β. Although the physiological significance of this acute IL-1β secretion remains unclear, our present data imply that Kir2.1 translocation functions as a regulator of IL-1β secretion, and therefore becomes a potential target to control cytokine release from microglia.

    AIM: Restrictions such as physical distancing and online learning for college students were implemented due to the COVID-19 pandemic. Owing to this, students may experience psychological distress from social isolation and loneliness. Nursing students are subjected to an exacerbated level of distress during the pandemic due to their role as health professionals. Therefore, the present study aimed to investigate the level of anxiety and depression among Japanese nursing students, according to their perceived vulnerability to COVID-19. METHODS: A total of 281 college students (104 nursing students and 177 other college students) responded to a web-based anonymous questionnaire survey from 18 August to 31 October 2020. The Hospital Anxiety and Depression Scale was used to evaluate anxiety (HADS-A) and depression (HADS-D). Perceived vulnerability to COVID-19 was assessed using the Perceived Vulnerability to Disease Scale. RESULTS: In both groups of students, the prevalence of both anxiety (30.5% in nursing students; 69.5% in others) and depressive symptoms (31.1% in nursing students; 68.9% in others) were remarkably high. There were no significant differences in anxiety and depression between nursing and other students after adjusting for perceived vulnerability to COVID-19 plus socio-demographic characteristics and stress coping styles. Perceived vulnerability and its interactions with nursing did not show a significant association with either depression or anxiety. CONCLUSION: This study highlights the need for greater support and preventive strategies for mental health problems for college students during the COVID-19 pandemic regardless of perceived vulnerability.

    Major depressive disorder (MDD) is associated with repeated exposure to environmental stress. Autophagy is activated under various stress conditions that are associated with several diseases in the brain. This study was aimed at elucidating the autophagy signaling changes in the prefrontal cortex (PFC) under repeated social defeat (RSD) to investigate the involvement of microglial autophagy in RSD-induced behavioral changes. We found that RSD stress, an animal model of MDD, significantly induced initial autophagic signals followed by increased transcription of autophagy-related genes (Atg6, Atg7, and Atg12) in the PFC. Similarly, significantly increased transcripts of ATGs (Atg6, Atg7, Atg12, and Atg5) were confirmed in the postmortem PFC of patients with MDD. The protein levels of the prefrontal cortical LC3B were significantly increased, whereas p62 was significantly decreased in the resilient but not in susceptible mice and patients with MDD. This indicates that enhanced autophagic flux may alleviate stress-induced depression. Furthermore, we identified that FKBP5, an early-stage autophagy regulator, was significantly increased in the PFC of resilient mice at the transcript and protein levels. In addition, the resilient mice exhibited enhanced autophagic flux in the prefrontal cortical microglia, and the autophagic deficiency in microglia aggravated RSD-induced social avoidance, indicating that microglial autophagy involves stress-induced behavioral changes.

    It has been hypothesized that a higher genetic risk of bipolar disorder (BD) is associated with greater creativity. Given the clinical importance of bipolar disorder and the importance of creativity to human society and cultural development, it is essential to reveal their associations and the neural basis of the genetic risk of bipolar disorder to gain insight into its etiology. However, despite the previous demonstration of the associations of polygenic risk score (PRS) of BD and creative jobs, the associations of BD-PRS and creativity measured by the divergent thinking (CMDT) and regional gray matter volume (rGMV) as well as regional white matter volume (rWMV) have not been investigated. Using psychological analyses and whole-brain voxel-by-voxel analyses, we examined these potential associations in 1558 young, typically developing adult students. After adjusting for confounding variables and multiple comparisons, a greater BD-PRS was associated with a greater total CMDT fluency score, and a significant relationship was found in fluency subscores. A greater BD-PRS was also associated with lower total mood disturbance. Neuroimaging analyses revealed that the BD-PRS was associated with greater rGMV in the right inferior frontal gyrus, which is a consistently affected area in BD, as well as a greater rWMV in the left middle frontal gyrus, which has been suggested to play a central role in the increased creativity associated with the risk of BD with creativity. These findings suggest a relationship between the genetic risk of BD and CMDT and prefrontal cortical structures among young educated individuals.

    Neural inflammation is associated with cognitive decline, especially learning and memory. Tumor necrosis factor α (TNFα) is a major cytokine generated during neuroinflammation. Previous studies indicated that TNFα impairs hippocampus-dependent memory including contextual fear and spatial memories. However, it is unknown which memory processes are impaired by TNFα. Here, we show that TNFα blocked the retrieval and reconsolidation of contextual fear and spatial memories. Micro-infusion of TNFα into the dorsal hippocampus at 6-18 h before retrieval impaired the retrieval of contextual fear memory, although micro-infusion before contextual fear conditioning had no effect on memory formation. Interestingly, hippocampal TNFα micro-infusion before memory retrieval decreased freezing responses, even at 24 h after retrieval, suggesting that TNFα impairs the reconsolidation of contextual fear memory. Similarly, hippocampal TNFα micro-infusion impaired the retrieval and reconsolidation of spatial memory in the Morris water maze. Consistent with these observations, hippocampal TNFα micro-infusion before retrieval blocked the induction of c-fos expression in the hippocampus, which is a marker of neural activation, in response to the retrieval of contextual fear memory. Collectively, our findings indicate that TNFα negatively regulates the retrieval and reconsolidation of hippocampus-dependent memory.

    Recent evidence has indicated that the disruption of oligodendrocytes may be involved in the pathogenesis of depression. Genetic factors are likely to affect trait factors, such as characteristics, rather than state factors, such as depressive symptoms. Previously, a negative self-schema had been proposed as the major characteristic of constructing trait factors underlying susceptibility to depression. Thus, the association between a negative self-schema and the functional single nucleotide polymorphism (SNP) rs1059004 in the <italic>OLIG2</italic> gene, which influences <italic>OLIG2</italic> gene expression, white matter integrity, and cerebral blood flow, was evaluated. A total of 546 healthy subjects were subjected to genotype and psychological evaluation using the Beck Depression Inventory-II (BDI-II) and the Brief Core Schema Scale (BCSS). The rs1059004 SNP was found to be associated with the self-schema subscales of the BCSS and scores on the BDI-II in an allele dose-dependent manner, and to have a predictive impact on depressive symptoms via a negative-self schema. The results suggest the involvement of a genetic factor regulating oligodendrocyte function in generating a negative-self schema as a trait factor underlying susceptibility to depression.

    In this study, the extent to which different emotions of pregnant women can be predicted based on heart rate-relevant information as indicators of autonomic nervous system functioning was explored using various machine learning algorithms. Nine heart rate-relevant autonomic system indicators, including the coefficient of variation R-R interval (CVRR), standard deviation of all NN intervals (SDNN), and square root of the mean squared differences of successive NN intervals (RMSSD), were measured using a heart rate monitor (MyBeat) and four different emotions including "happy," as a positive emotion and "anxiety," "sad," "frustrated," as negative emotions were self-recorded on a smartphone application, during 1 week starting from 23rd to 32nd weeks of pregnancy from 85 pregnant women. The k-nearest neighbor (k-NN), support vector machine (SVM), logistic regression (LR), random forest (RF), naïve bayes (NB), decision tree (DT), gradient boosting trees (GBT), stochastic gradient descent (SGD), extreme gradient boosting (XGBoost), and artificial neural network (ANN) machine learning methods were applied to predict the four different emotions based on the heart rate-relevant information. To predict four different emotions, RF also showed a modest area under the receiver operating characteristic curve (AUC-ROC) of 0.70. CVRR, RMSSD, SDNN, high frequency (HF), and low frequency (LF) mostly contributed to the predictions. GBT displayed the second highest AUC (0.69). Comprehensive analyses revealed the benefits of the prediction accuracy of the RF and GBT methods and were beneficial to establish models to predict emotions based on autonomic nervous system indicators. The results implicated SDNN, RMSSD, CVRR, LF, and HF as important parameters for the predictions.

    Previous studies have indicated associations between several OLIG2 gene single-nucleotide polymorphisms (SNPs) and susceptibility to schizophrenia among Caucasians. Consistent with these findings, postmortem brain and diffusion tensor imaging studies have indicated that the schizophrenia-risk-associated allele (A) in the OLIG2 SNP rs1059004 predicts lower OLIG2 gene expression in the dorsolateral prefrontal cortex (DLPFC) of schizophrenia patients and reduced white matter (WM) integrity of the corona radiata in normal brains among Caucasians. In an effort to replicate the association between this variant and WM integrity among healthy Japanese, we found that the number of A alleles was positively correlated with WM integrity in some fiber tracts, including the right posterior limb of the internal capsule, and with mean blood flow in a widespread area, including the inferior frontal operculum, orbital area, and triangular gyrus. Because the A allele affected WM integrity in opposite directions in Japanese and Caucasians, we investigated a possible association between the OLIG2 gene SNPs and the expression level of OLIG2 transcripts in postmortem DLPFCs. We evaluated rs1059004 and additional SNPs in the 5' upstream and 3' downstream regions of rs1059004 to cover the broader region of the OLIG2 gene. The 2 SNPs (rs1059004 and rs9653711) had opposite effects on OLIG2 gene expression in the DLPFC in Japanese and Caucasians. These findings suggest ethnicity-dependent opposite effects of OLIG2 gene SNPs on WM integrity and OLIG2 gene expression in the brain, which may partially explain the failures in replicating associations between genetic variants and psychiatric phenotypes among ethnicities.

    <title>Abstract</title>The nature of the recovery process of posttraumatic stress disorder (PTSD) symptoms is multifactorial. The Massive Parallel Limitless-Arity Multiple-testing Procedure (MP-LAMP), which was developed to detect significant combinational risk factors comprehensively, was utilized to reveal hidden combinational risk factors to explain the long-term trajectory of the PTSD symptoms. In 624 population-based subjects severely affected by the Great East Japan Earthquake, 61 potential risk factors encompassing sociodemographics, lifestyle, and traumatic experiences were analyzed by MP-LAMP regarding combinational associations with the trajectory of PTSD symptoms, as evaluated by the Impact of Event Scale-Revised score after eight years adjusted by the baseline score. The comprehensive combinational analysis detected 56 significant combinational risk factors, including 15 independent variables, although the conventional bivariate analysis between single risk factors and the trajectory detected no significant risk factors. The strongest association was observed with the combination of short resting time, short walking time, unemployment, and evacuation without preparation (adjusted <italic>P</italic> value = 2.2 × 10−4, and raw <italic>P</italic> value = 3.1 × 10−9). Although short resting time had no association with the poor trajectory, it had a significant interaction with short walking time (<italic>P</italic> value = 1.2 × 10−3), which was further strengthened by the other two components (<italic>P</italic> value = 9.7 × 10−5). Likewise, components that were not associated with a poor trajectory in bivariate analysis were included in every observed significant risk combination due to their interactions with other components. Comprehensive combination detection by MP-LAMP is essential for explaining multifactorial psychiatric symptoms by revealing the hidden combinations of risk factors.

    <title>Abstract</title> The APOE ɛ4 allele is associated with a risk of Alzheimer’s disease in the elderly, with the association being pronounced in females. Conversely, findings of the effects of the APOE ɛ4 allele in young adults are mixed. Here, we investigated the sex–genotype interaction effects of the APOE ɛ4 allele on cognitive functions as well as brain structures among 1258 young adults. After adjusting for multiple comparisons, there were significant effects of the interaction between sex and the number of APOE ɛ4 allele on some speed tasks (e.g., simple processing speed tasks and the reverse Stroop task) as well as on regional white matter volume (rWMV). The observed sex–genotype interaction conferred better cognitive performance and greater rWMV in the anterior frontal and precentral white matter areas in females having more APOE ɛ4 alleles and reduced rWMV in the same areas in male having more APOE ɛ4 alleles. These findings support the long-debated antagonistic pleiotropic effects of the APOE ɛ4 allele in females.

    Numerous studies have reported that the Met allele of the brain-derived neurotrophic factor (BDNF) gene polymorphism reduces neural plasticity. A reduction in mean diffusivity (MD) in diffusion tensor imaging (DTI) characteristically reflects the neural plasticity that involves increased tissue components. In this study, we revealed that the number of Met-BDNF alleles was negatively associated with MD throughout the whole-brain gray and white matter areas of 743 subjects using DTI and whole-brain multiple regression analyses. Within the same sample, the region of interest analysis revealed that the number of Met-BDNF alleles significantly and positively correlated with the mean FA value in the body of the corpus callosum. In addition, we observed interaction effects between BDNF Val66Met polymorphism and daily physical activity levels on MD, but not FA, in significant clusters of the bilateral hemisphere (n = 577 subjects). Post-hoc multiple regression analyses revealed that after correcting for confounding variables, there was a significant negative correlation between the physical activity level and mean MD of the whole brain in the Val/Val group [standardized partial regression coefficient (β) = -0.196, P = 0.005, t = -2.825], but not in the Val/Met (β = 0.050, P = 0.412, t = 0.822) and Met/Met groups (β = 0.092, P = 0.382, t = 0.878). These results underscore the importance of the interaction between physical activity and the BDNF Val66Met polymorphism, which affects the plasticity of neural mechanisms.

    Genome-wide association studies have suggested that allelic variations in the CACNA1C gene confer susceptibility to schizophrenia and bipolar disorder only in women. Here we investigated the sex-specific effects of the CACNA1C variant rs1024582 on psychiatry-related traits, brain activity during tasks and rest, and brain volume in 1207 normal male and female subjects. After correcting for multiple comparisons, there were significant interaction effects between sex and the minor allele of this polymorphism on the hostile behavior subscale scores of the Coronary-Prone Type Scale mediated by higher scores in female carriers of the minor allele. Imaging analyses revealed significant interaction effects between sex and the minor allele on fractional amplitude of low-frequency fluctuations in the right dorsolateral prefrontal cortex and on brain activity during the 2-back task in areas of the right posterior cingulate cortex, right thalamus, and right hippocampus, which were all mediated by reduced activity in female carriers of the minor allele. Our results demonstrated that the rs1024582 risk variant of CACNA1C is associated with reduced activity in the frontolimbic regions at rest and during a working memory task as well as with greater hostility in females in the healthy population.

    Systemic platelet behaviors in experimental animals are often assessed by infusion of isotope-labeled platelets and measuring them under anesthesia. However, such procedures alter, therefore may not reveal, real-life platelet behaviors. 5-Hydroxytryptamine (5HT or serotonin) is present within limited cell-types, including platelets. In our studies, by measuring 5HT as a platelet-marker in non-anesthetized mice, we identified stimulation- and time-dependent accumulations in liver, lung, and/or spleen as important systemic platelet behaviors. For example, intravenous, intraperitoneal, or intragingival injection of lipopolysaccharide (LPS, a cell-wall component of Gram-negative bacteria), interleukin (IL)-1, or tumor necrosis factor (TNF)-α induced hepatic platelet accumulation (HPA) and platelet translocation into the sinusoidal and perisinusoidal spaces or hepatocytes themselves. These events occurred "within a few hours" of the injection, caused hypoglycemia, and exhibited protective or causal effects on hepatitis. Intravenous injection of larger doses of LPS into normal mice, or intravenous antigen-challenge to sensitized mice, induced pulmonary platelet accumulation (PPA), as well as HPA. These reactions occurred "within a few min" of the LPS injection or antigen challenge and resulted in shock. Intravenous injection of 5HT or a catecholamine induced a rapid PPA "within 6 s." Intravenous LPS injection, within a minute, increased the pulmonary catecholamines that mediate the LPS-induced PPA. Macrophage-depletion from liver and spleen induced "day-scale" splenic platelet accumulation, suggesting the spleen is involved in clearing senescent platelets. These findings indicate the usefulness of 5HT as a marker of platelet behaviors, and provide a basis for a discussion of the roles of platelets as both "defenders" and "guardians."

    Vascular endothelial growth factor (VEGF) plays a critical role in the angiogenesis and proliferation of various types of cells such as neurons, astroglia, and endothelial cells in the brain. A common polymorphism in the VEGF gene (-2578 C/A) is associated with circulating VEGF levels, cancers and Alzheimer's disease. Nonetheless, the effects of this polymorphism on normal human brain volume, arterial blood volume, and blood supply remain unclear. In this study, the effects of this polymorphism on the total gray matter volume (TGMV) and total white matter volume (TWMV) using T1-weighted structural images and the total arterial blood volume (TABV) and mean cerebral blood flow (mCBF) during rest using arterial spin labeling (ASL) in 765 young adult humans were investigated. Voxel-by-voxel whole-brain analyses of these measures were also performed. Multiple regression analyses with age and sex as covariates revealed that the VEGF genotype (number of C alleles) was significantly and positively correlated with TGMV, TWMV, and TABV as well as with regional gray and white matter volumes in widespread areas and regional arterial blood volume in some areas with high arterial blood volume. However, these regional associations were not seen when the corresponding global signal was included as a covariate in the multiple regression analyses, indicating that we failed to obtain evidence of region-specific associations between these brain measures and the genotype. The results suggest that the VEGF-2578C allele, is associated with changes in the vascular system that lead to increased blood volume and larger brain volume.

    The 5-repeat allele of a common length polymorphism in the gene that encodes the dopamine D4 receptor (DRD4) is robustly associated with the risk of attention deficit hyperactivity disorder (ADHD) and substantially exists in Asian populations, which have a lower ADHD prevalence. In this study, we investigated the effect of this allele on microstructural properties of the brain and on its functional activity during externally directed attention-demanding tasks and creative performance in the 765 Asian subjects. For this purpose, we employed diffusion tensor imaging, N-back functional magnetic resonance imaging paradigms, and a test to measure creativity by divergent thinking. The 5-repeat allele was significantly associated with increased originality in the creative performance, increased mean diffusivity (the measure of how the tissue includes water molecules instead of neural and vessel components) in the widespread gray and white matter areas of extensive areas, particularly those where DRD4 is expressed, and reduced task-induced deactivation in the areas that are deactivated during the tasks in the course of both the attention-demanding working memory task and simple sensorimotor task. The observed neural characteristics of 5-repeat allele carriers may lead to an increased risk of ADHD and behavioral deficits. Furthermore, the increased originality of creative thinking observed in the 5-repeat allele carriers may support the notion of the side of adaptivity of the widespread risk allele of psychiatric diseases.

    Previous neuroscientific studies have shown that the dopaminergic system plays an important role in creative potential measured by divergent thinking (CPMDT), emotional control, and motivational state. However, although associations between two of these four components have been previously established (e.g., the association between CPMDT and emotional control, the association between CPMDT and motivational state, etc.), the interactions between these four remain unknown. The purpose of this study was to reveal these interactions using path analyses. The Taq1A polymorphism of the dopamine D2 receptor (DRD2) gene was used for this purpose. For measuring emotional intelligence (EI), we used the Japanese version of the Emotional Intelligence Scale. CPMDT was measured using the S-A creativity test. Motivational state was measured using the Vigor subscale of the Japanese version of the Profile of Mood Scale (POMS). Data from 766 healthy, right-handed individuals (426 men and 340 women; 20.7 ± 1.9 years of age) were used in this study. There were significant and robust positive relationships among measures of CPMDT, EI, and motivational state across sex. In addition, the polymorphism of the DRD2 gene was significantly associated with EI, specifically in females. Path analysis in females indicates that the model in which (a) the DRD2 polymorphism primarily facilitates EI, (b) EI in turn facilitates CPMDT and leads to a better motivational state, and (c) a better motivational state also directly facilitates CPMDT explains the data in the most accurate manner. This study suggested a comprehensive picture of the cascade of the associations among dopamine, EI, motivational state, and CPMDT at least in females.

    気分安定薬4剤(リチウム、バルプロ酸、カルバマゼピン、ラモトリジン)を、ヒト脳内の3種の細胞(神経細胞、アストロサイト、オリゴデンドロサイト)に由来する各培養細胞に投与し、遺伝子発現プロファイルへの影響をマイクロアレイ解析により検討した。その結果、遺伝子発現プロファイルに対してリチウムとバルプロ酸は相互に比較的類似した影響を及ぼし、カルバマゼピンとラモトリジンは相互に比較的類似した影響を及ぼした。遺伝子発現プロファイルへの影響を3種の細胞ごとにみると、バルプロ酸は全ての細胞に比較的共通した発現変化をもたらしたのに対し、他の3剤による発現変化は細胞ごとに大きく異なった。

    ストレスはうつ様行動を引き起こし、オートファジーはストレス条件下で活性化されることが考えられる。本研究では反復社会挫折ストレス (Repeated social defeat; RSD) による行動変化、およびミクログリアにおけるオートファジーの関与を明らかにすることを目的とした。RSD を負荷したマウスは、脳内における初期のオートファジーシグナル (initial autophagy signaling) の活性が観察された。その中、前頭前野でのオートファジー関連遺伝子（Atg6、Atg7、およびAtg12） の発現増加を見出したが、海馬においてはオートファジーの変動が見られなかった。同様に、うつ病患者の死後脳の前頭前野においても、ATG （Atg6、Atg7、Atg12、およびAtg5） の有意な遺伝子の発現増加が明らかになった。また、マウスの前頭前野におけるオートファゴソーム結合タンパク質 LC3B が有意に増加した一方、オートファゴソーム分解マーカーである p62 は耐性群マウスで有意に減少した。しかし、脆弱性群マウスや うつ病患者において、LC3B および p62 の変動は見られなかった。以上の結果から、オートファジーフラックス (autophagic flux) の亢進がストレス誘発したうつ様行動を軽減する可能性が示唆された。さらに、initial autophagy signaling の制御因子である FKBP5 が耐性群マウスの前頭前野で遺伝子転写およびタンパク質レベルで有意に増加した。また、耐性群マウスにおいて、前頭前野のミクログリアにおける autophagic flux の亢進を示し、ミクログリアのオートファジー欠損 (Cx3cr1Cre+;Atg7flox/flox) によって、RSD 誘発した回避行動を悪化させた。

    胎生期の母体感染が胎児の脳発達に影響を及ぼし、成長後の統合失調症の発症率を高めることが知られている。母体感染による統合失調症の発症機構を解明するために、統合失調症モデルマウスを用い、脳内の遺伝子発現およびDNAメチル化の変化を全ゲノム規模で検討した。その結果、統合失調症の発症に関わる遺伝子を特定し、雌マウスにおいて顕著な発現変動が見られた。また、統合失調症の女性罹患者の死後脳においても、雌マウスと同様の変化が確認された。
