    Sporadic inclusion body myositis (sIBM) is a muscle disease in older people and is characterized by inflammatory cell invasion into intact muscle fibers and rimmed vacuoles. The pathomechanism of sIBM is not fully elucidated yet, and controversy exists as to whether sIBM is a primary autoimmune disease or a degenerative muscle disease with secondary inflammation. Previously, we established a method of collecting CD56-positive myoblasts from human skeletal muscle biopsy samples. We hypothesized that the myoblasts derived from these patients are useful to see the cell-autonomous pathomechanism of sIBM. With these resources, myoblasts were differentiated into myotubes, and the expression profiles of cell-autonomous pathology of sIBM were analyzed. Myoblasts from three sIBM cases and six controls were differentiated into myotubes. In the RNA-sequencing analysis of these "myotube" samples, 104 differentially expressed genes (DEGs) were found to be significantly upregulated by more than twofold in sIBM, and 13 DEGs were downregulated by less than twofold. For muscle biopsy samples, a comparative analysis was conducted to determine the extent to which "biopsy" and "myotube" samples differed. Fifty-three DEGs were extracted of which 32 (60%) had opposite directions of expression change (e.g., increased in biopsy vs decreased in myotube). Apolipoprotein E (apoE) and transmembrane protein 8C (TMEM8C or MYMK) were commonly upregulated in muscle biopsies and myotubes from sIBM. ApoE and myogenin protein levels were upregulated in sIBM. Given that enrichment analysis also captured changes in muscle contraction and development, the triggering of muscle atrophy signaling and abnormal muscle differentiation via MYMK or myogenin may be involved in the pathogenesis of sIBM. The presence of DEGs in sIBM suggests that the myotubes formed from sIBM-derived myoblasts revealed the existence of muscle cell-autonomous degeneration in sIBM. The catalog of DEGs will be an important resource for future studies on the pathogenesis of sIBM focusing on primary muscle degeneration.

    Muscle contractile activity stimulates intramuscular recruitment of immune cells including neutrophils emerging to serve as a prerequisite for exerting proper muscular performance, although the underlying mechanisms and their contributions to myokine upregulation remain ill-defined. We previously reported that pharmacological inhibition of CX3CR1, a fractalkine receptor, dampens gnawing-dependent neutrophil recruitment into masseter muscles along with compromising their masticatory activity. By employing a running exercise model, we herein demonstrated that hindlimb muscles require collaborative actions of both CX3CR1- and CXCR2-mediated signals for achieving neutrophil recruitment, upregulation of myokines including interleukin (IL)-6, enhanced GLUT4 translocation, and adequate endurance capability. Mechanistically, we revealed that a combination of CX3CR1 and CXCR2 antagonists, i.e., AZD8797 and SB2205002, inhibits exercise-inducible ICAM-1 and fractalkine upregulations in the area of the endothelium and muscle-derived CXCL1 upregulation, both of which apparently contribute to the intramuscular neutrophil accumulation in working muscles. Intriguingly, we also observed that 2 h of running results in intramuscular augmentation of innate lymphoid type 2 cells (ILC2s) markers, i.e., Bcl11b mRNA levels and anti-GATA-3-antibody-positive signals, and that these effects are completely abolished by administration of the combination of CX3CR1 and CXCR2 antagonists. Taken together, our findings strongly suggest that the exercise-evoked regional interplay among working myofibers, the adjacent endothelium and recruited immune cells including neutrophils and possibly ILC2s, mediated through these local factors, plays a key role in organization of the intramuscular microenvironment supporting the performance of hindlimb muscles during running.

    Type 2 diabetes mellitus (T2DM), a lifestyle-related disease, is developed due to eating habits and decreased physical activity. Diabetes also increases the risk of cancer and major neurodegenerative diseases; controlling the onset of diabetes helps prevent various illnesses. Eating seaweed, such as Undaria pinnatifida (wakame), is a part of the Asian food culture. Therefore, we analyzed the antidiabetic effect of wakame intake using the high-fat diet-induced diabetes mouse model. Furthermore, we analyzed the effect of wakame extract on the cell membrane translocation of glucose transporter-4 (GLUT4) and activation of insulin signal molecules, such as AKT and AMPK, in insulin-sensitive tissues. Differentiated C2C12 cells were incubated with wakame components. The membrane translocation of GLUT4 and phosphorylation of AKT and AMPK were investigated with immunofluorescence staining and Western blotting, respectively. Also, male C57BL/6J mice were fed the normal diet (ND), high-fat diet (HFD), ND with 1% wakame powder (ND + W), or HFD with 1% wakame powder (HFD + W). We evaluated the effect of wakame intake on high-fat diet-induced glucose intolerance using an oral glucose tolerance test. Moreover, we analyzed insulin signaling molecules, such as GLUT4, AKT, and AMPK, in muscle using Western blotting. GLUT4 membrane translocation was promoted by wakame components. Also, GLUT4 levels and AKT and AMPK phosphorylation were significantly elevated by wakame components in C2C12 cells. In addition, the area under the curve (AUC) of the HFD + W group was significantly smaller than that of the HFD group. Furthermore, the level of GLUT4 in the muscle was increased in the wakame intake group. This study revealed that various wakame components exerted antidiabetic effects on the mice on a high-fat diet by promoting glucose uptake in the skeletal muscle, enhancing GLUT4 levels, and activating AKT and AMPK.

    Abstract This study investigates the antibacterial properties of CuCrO2 (CCO) films fabricated by sputter deposition followed by calcination. The effects of the doped magnesium and the film fabrication in nitrogen atmosphere on both CCO crystallinity and antibacterial properties are compared. The antibacterial properties are evaluated using the plate counting method, and the crystallinity of the films are analyzed by X-ray diffraction. The results show the proliferation of Escherichia coli colonies that can be suppressed within 3 h, with magnesium-doped CCO showing the best antibacterial properties of all samples. This is explained by the formation of CuO byproduct during fabrication.

    Heterotypic endomembrane fusion between static GLUT4-containing vesicles and traveling transferrin receptor-containing endosomes triggers insulin-responsive translocation of the GLUT4 glucose transporter. Here, we provide a protocol for preparing BODIPY-based fluorescent sensor molecules allowing detection of heterotypic endomembrane fusion through dequenching via streptavidin-biotin binding and ratiometrically analyzing insulin-responsive events with live-cell imaging. Although this protocol is for evaluating specific fusion processes relating GLUT4 translocation, it is also applicable to assessing other processes so long as sensor molecules can properly label target molecules. For complete details on the use and execution of this protocol, please refer to Hatakeyama et al. (2022).

    The physiological significance of skeletal muscle as a secretory organ is now well known but we can only speculate as to the existence of as-yet-unidentified myokines, especially those upregulated in response to muscle contractile activity. We first attempted to establish an "insert-chamber based in vitro exercise model" allowing the miniature but high cell-density culture state enabling highly developed contractile human myotubes to be readily obtained by applying electric pulse stimulation (EPS). By employing this in vitro exercise model, we identified R-spondin 3 (RSPO3) as a novel contraction-inducible myokine produced by cultured human myotubes. Contraction-dependent muscular RSPO3 mRNA upregulation was confirmed in skeletal muscles of mice subjected to sciatic nerve mediated in situ contraction as well as those of mice after 2 h of running. Pharmacological in vitro experiments demonstrated a relatively high concentration of metformin (millimolar range) to suppress the contraction-inducible mRNA upregulation of human myokines including RSPO3, interleukin (IL)-6, IL-8 and CXCL1. Our data also suggest human RSPO3 to be a paracrine factor that may positively participate in the myogenesis processes of myoblasts and satellite cells. Thus, the "insert chamber-based in vitro exercise model" is a potentially valuable research tool for investigating contraction-inducible biological responses of human myotubes usually exhibiting poorer contractility development even in the setting of EPS treatment.

    Abstract The gut environment, including the microbiota and its metabolites and short-chain fatty acids (SCFA), is essential for health maintenance. It is considered that functional recovery treatment for masticatory dysphagia affects the composition of the gut microbiota, indicating that habitual mastication, depending on the hardness of the food, may affect the gut microbiota and environment. However, the impact of chronic powdered diet feeding on the colonic condition and motility remains unclear. Here, we evaluated various colonic features in mice fed with powdered diets for a long-term and a mouse model with masticatory behavior. We observed a decreased abundance of the SCFA-producing bacterial genera in the ceca of the powdered diet-fed mice. Based on the importance of SCFAs in gut immune homeostasis and motility, interestingly, powdered diet feeding also resulted in constipation-like symptoms due to mild colitis, which were ameliorated by the administration of a neutrophil-depleting agent and neutrophil elastase inhibitors. Lastly, the suppressed colonic motility in the powdered diet-fed mice was significantly improved by loading masticatory activity for 2 h. Thus, feeding habits with appropriate masticatory activity and stimulation may play a key role in providing a favorable gut environment based on interactions between the gut microbiota and host immune system.

    Accumulation of uric acid (UA) during muscular trauma is a factor involved in the development of muscle hyperalgesia. Neutrophil extracellular traps (NETs), DNA-based reticular structures to capture UA, play a central role in the pain onset of gout attacks; however, the involvement of NETs via the elevation of local UA level in muscle hyperalgesia due to injuries from muscle overuse remains unknown. The triceps surae muscles (TSMs) in the unilateral hindlimb of mice were electrically stimulated to induce excessive muscle contraction. Mechanical withdrawal thresholds, tissue UA levels, neutrophil recruitment, and protein amount of citrullinated histone 3 (citH3), a major marker of NETs, were investigated. Furthermore, whether neutrophil depletion, extracellular DNA cleavage, and administration of the urate-lowering agent febuxostat improved muscle hyperalgesia caused by NET formation was examined. CitH3 expression upon neutrophil recruitment was significantly increased in the stimulated TSMs with increased tissue UA levels, whereas febuxostat administration improved muscle hyperalgesia with decreased citH3 and tissue UA levels, as observed in neutrophil depletion and extracellular DNA digestion. The underlying mechanism of muscle hyperalgesia associated with locally recruited neutrophils forming NETs due to increased tissue UA levels potentially plays a significant role in creating a vicious circle of muscle pain.

    Contractile activity is a fundamental property of skeletal muscles. We describe the establishment of a "feeder-supported in vitro exercise model" using human-origin primary satellite cells, allowing highly-developed contractile myotubes to readily be generated by applying electrical pulse stimulation (EPS). The use of murine fibroblasts as the feeder cells allows biological responses to EPS in contractile human myotubes to be selectively evaluated with species-specific analyses such as RT-PCR. We successfully applied this feeder-supported co-culture system to myotubes derived from primary satellite cells obtained from sporadic inclusion body myositis (sIBM) patients who are incapable of strenuous exercise testing. Our results demonstrated that sIBM myotubes possess essentially normal muscle functions, including contractility development, de novo sarcomere formation, and contraction-dependent myokine upregulation, upon EPS treatment. However, we found that some of sIBM myotubes, but not healthy control myotubes, often exhibit abnormal cytoplasmic TDP-43 accumulation upon EPS-evoked contraction, suggesting potential pathogenic involvement of the contraction-inducible TDP-43 distribution peculiar to sIBM. Thus, our "feeder-supported in vitro exercise model" enables us to obtain contractile human-origin myotubes, potentially utilizable for evaluating exercise-dependent intrinsic and pathogenic properties of patient muscle cells. Our approach, using feeder layers, further expands the usefulness of the "in vitro exercise model".

    Skeletal muscle health is important for the prevention of various age-related diseases. The loss of skeletal muscle mass, which is known as sarcopenia, underlies physical disability, poor quality of life and chronic diseases in elderly people. The transcription factor NRF2 plays important roles in the regulation of the cellular defense against oxidative stress, as well as the metabolism and mitochondrial activity. To determine the contribution of skeletal muscle NRF2 to exercise capacity, we conducted skeletal muscle-specific inhibition of KEAP1, which is a negative regulator of NRF2, and examined the cell-autonomous and non-cell-autonomous effects of NRF2 pathway activation in skeletal muscles. We found that NRF2 activation in skeletal muscles increased slow oxidative muscle fiber type and improved exercise endurance capacity in female mice. We also observed that female mice with NRF2 pathway activation in their skeletal muscles exhibited enhanced exercise-induced mobilization and β-oxidation of fatty acids. These results indicate that NRF2 activation in skeletal muscles promotes communication with adipose tissues via humoral and/or neuronal signaling and facilitates the utilization of fatty acids as an energy source, resulting in increased mitochondrial activity and efficient energy production during exercise, which leads to improved exercise endurance.

    <jats:p>Sporadic inclusion body myositis (sIBM) is the most common idiopathic inflammatory myopathy, and several reports have suggested that mitochondrial abnormalities are involved in its etiology. We recruited 9 sIBM patients and found significant histological changes and an elevation of growth differential factor 15 (GDF15), a marker of mitochondrial disease, strongly suggesting the involvement of mitochondrial dysfunction. Bioenergetic analysis of sIBM patient myoblasts revealed impaired mitochondrial function. Decreased ATP production, reduced mitochondrial size and reduced mitochondrial dynamics were also observed in sIBM myoblasts. Cell vulnerability to oxidative stress also suggested the existence of mitochondrial dysfunction. Mitochonic acid-5 (MA-5) increased the cellular ATP level, reduced mitochondrial ROS, and provided protection against sIBM myoblast death. MA-5 also improved the survival of sIBM skin fibroblasts as well as mitochondrial morphology and dynamics in these cells. The reduction in the gene expression levels of Opa1 and Drp1 was also reversed by MA-5, suggesting the modification of the fusion/fission process. These data suggest that MA-5 may provide an alternative therapeutic strategy for treating not only mitochondrial diseases but also sIBM.</jats:p>

    Despite successful clinical application of non-equilibrium atmospheric pressure plasma (APP), the details of the molecular mechanisms underlying APP-inducible biological responses remain ill-defined. We previously reported that exposure of 3T3L1 cells to APP-irradiated buffer raised the cytoplasmic free Ca2+ ([Ca2+]i) concentration by eliciting Ca2+ influx in a manner sensitive to transient receptor potential (TRP) channel inhibitors. However, the precise identity of the APP-responsive channel molecule(s) remains unclear. In the present study, we aimed to clarify channel molecule(s) responsible for indirect APP-responsive [Ca2+]i rises. siRNA-mediated silencing experiments revealed that TRPA1 and TRPV1 serve as the major APP-responsive Ca2+ channels in 3T3L1 cells. Conversely, ectopic expression of either TRPA1 or TRPV1 in APP-unresponsive C2C12 cells actually triggered [Ca2+]i elevation in response to indirect APP exposure. Desensitization experiments using 3T3L1 cells revealed APP responsiveness to be markedly suppressed after pretreatment with allyl isothiocyanate or capsaicin, TRPA1 and TRPV1 agonists, respectively. APP exposure also desensitized the cells to these chemical agonists, indicating the existence of a bi-directional heterologous desensitization property of APP-responsive [Ca2+]i transients mediated through these TRP channels. Mutational analyses of key cysteine residues in TRPA1 (Cys421, Cys621, Cys641, and Cys665) and in TRPV1 (Cys258, Cys363, and Cys742) have suggested that multiple reactive oxygen and nitrogen species are intricately involved in activation of the channels via a broad range of modifications involving these cysteine residues. Taken together, these observations allow us to conclude that both TRPA1 and TRPV1 channels play a pivotal role in evoking indirect APP-dependent [Ca2+]i responses.

    Mutations in the leucine-rich repeat kinase 2 (LRRK2) gene are associated with Parkinson's disease. LRRK2 is a large protein with multiple functional domains, including a guanosine 5'-triphosphate (GTP)-binding domain and a protein kinase domain. Recent studies indicated that the members of the Rab GTPase family, Rab8a and Rab10, which are involved in the membrane transport of the glucose transporter type 4 (GLUT4) during insulin-dependent glucose uptake, are phosphorylated by LRRK2. However, the physiological role of LRRK2 in the regulation of glucose metabolism is largely unknown. In the present study, we investigated the role of LRRK2 using dexamethasone (DEX)-induced glucose intolerance in mice. LRRK2 knockout (KO) mice exhibited suppressed glucose intolerance, even after treatment with DEX. The phosphorylation of LRRK2, Rab8a and Rab10 was increased in the adipose tissues of DEX-treated wild-type mice. In addition, inhibition of the LRRK2 kinase activity prevented the DEX-induced inhibition of GLUT4 membrane translocation and glucose uptake in cultured 3T3-L1 adipocytes. These results suggest that LRRK2 plays an important role in glucose metabolism in adipose tissues.

    KEY POINTS: Fractalkine receptor antagonist inhibited neutrophil recruitment to masseter muscles and exacerbated fatigability during masticatory activity. Fractalkine-mediated neutrophil recruitment is required for both upregulation of myokines (CXCL1, interleukin-6) and enhanced GLUT4 translocation in response to masticatory activity. Fractalkine and intercellular adhesion molecule-1 expression in endothelial cells increased in response to masticatory activity. In vitro experiments demonstrated that contracting myotubes lack the ability to upregulate fractalkine but revealed that endothelial fractalkine upregulation is induced using a conditioned medium of contracting myotubes. ABSTRACT: Physical exercise stimulates neutrophil recruitment within working skeletal muscle, although its underlying mechanisms remain ill-defined. By employing a masticatory behaviour (gnawing) model, we demonstrate the importance of intramuscular paracrine and autocrine systems that are triggered by muscle contractile activity and reliant upon fractalkine/CX3CL1-mediated signals. These signals were revealed to be required for achieving proper GLUT4 translocation and glucose uptake to meet the glucose demands for fatigue alleviation. Specifically, fractalkine expression and neutrophil recruitment both increased in the masseter muscle tissues upon masticatory activity. Importantly, a fractalkine antagonist inhibited neutrophil accumulation and exacerbated fatigability during masticatory activity. We found that fractalkine-dependent neutrophil recruitment is required for both upregulation of myokines (i.e. CXCL1 and interleukin-6) and enhanced GLUT4 translocation in response to gnawing activity. Immunofluorescence analysis of masseter muscles demonstrated that fractalkine and intercellular adhesion molecule-1 expression are both upregulated in endothelial cells but not in myofibres. The in vitro exercise model further revealed that contractile activity failed to stimulate fractalkine upregulation in myotubes, implying that fractalkine is not a myokine (myofibre-derived factor). Nevertheless, endothelial fractalkine expression was markedly stimulated by a conditioned medium from the contracting myotubes. Moreover, intercellular adhesion molecule-1, a key adhesion molecule for neutrophils, was upregulated in endothelial cells by fractalkine. Taken together, our findings strongly suggest that endothelial fractalkine serves as a key factor for organizing a physiologically beneficial intramuscular microenvironment by recruiting neutrophils in response to relatively mild exercise (i.e. masticatory muscle activity).

    The neuropathological hallmarks of Parkinson's disease (PD) include the appearance of α-synuclein (α-SYN)-positive Lewy bodies (LBs) and the loss of catecholaminergic neurons. Thus, a potential mechanism promoting the uptake of extracellular α-SYN may exist in susceptible neurons. Of the various differentially expressed proteins, we are interested in flotillin (FLOT)-1 because this protein is highly expressed in the brainstem catecholaminergic neurons and is strikingly up-regulated in PD brains. In this study, we found that extracellular monomeric and fibrillar α-SYN can potentiate FLOT1-dopamine transporter (DAT) binding and pre-endocytic clustering of DAT on the cell surface, thereby facilitating DAT endocytosis and down-regulating its transporter activity. Moreover, we demonstrated that α-SYN itself exploited the DAT endocytic process to enter dopaminergic neuron-like cells, and both FLOT1 and DAT were found to be the components of LBs. Altogether, these findings revealed a novel role of extracellular α-SYN on cellular trafficking of DAT and may provide a rationale for the cell type-specific, functional, and pathologic alterations in PD.-Kobayashi, J., Hasegawa, T., Sugeno, N., Yoshida, S., Akiyama, T., Fujimori, K., Hatakeyama, H., Miki, Y., Tomiyama, A., Kawata, Y., Fukuda, M., Kawahata, I., Yamakuni, T., Ezura, M., Kikuchi, A., Baba, T., Takeda, A., Kanzaki, M., Wakabayashi, K., Okano, H., Aoki, M.

    Contraction of cultured myotubes with application of electric pulse stimulation (EPS) has been utilized for investigating cellular responses associated with actual contractile activity. However, cultured myotubes derived from human subjects often exhibit relatively poor EPS-evoked contractile activity, resulting in minimal contraction-inducible responses (i.e. myokine secretion). We herein describe an "in vitro exercise model", using hybrid myotubes comprised of human myoblasts and murine C2C12 myoblasts, exhibiting vigorous contractile activity in response to EPS. Species-specific analyses including RT-PCR and the BioPlex assay allowed us to separately evaluate contraction-inducible gene expressions and myokine secretions from human and mouse constituents of hybrid myotubes. The hybrid myotubes, half of which had arisen from primary human satellite cells obtained from biopsy samples, exhibited remarkable increases in the secretions of human cytokines (myokines) including interleukins (IL-6, IL-8, IL-10, and IL16), CXC chemokines (CXCL1, CXCL2, CXCL5, CXCL6, CXCL10), CC chemokines (CCL1, CCL2, CCL7, CCL8, CCL11, CCL13, CCL16, CCL17, CCL19, CCL20, CCL21, CCL22, CCL25, CCL27), and IFN-γ in response to EPS-evoked contractile activity. Together, these results indicate that inadequacies arising from human muscle cells are effectively overcome by fusing them with murine C2C12 cells, thereby supporting the development of contractility and the resulting cellular responses of human-origin muscle cells. Our approach, using hybrid myotubes, further expands the usefulness of the "in vitro exercise model".

    Biomechanics of the cell indicates the inner structure and viability of the cell. Mechanical properties are represented by acoustic properties such as speed of sound (SOS) or acoustic impedance. In the present study, cellular resolution scanning acoustic microscope combined with optical microscope (OptSAM) is developed to observe the change of mechanical properties in cell differentiation. Main part of the OptSAM was consisted of 350 MHz ultrasound transducer mechanically scanned by a piezo-actuator. Thickness, SOS, acoustic impedance, density and elastic bulk modulus of the cell were deduced by the ultrasound responses in both time domain and frequency domain. C2C12 cell changing its form from myoblast to myotube was observed by OptSAM. The value of bulk modulus slightly increased in response to differentiation process. OptSAM non-invasively provides important information on biomechanics of cells without contact or staining.

    Metabolic immunomodulation involving IL-1 has been investigated for unfavorable metabolic effects, including obesity, but a potentially favorable role for IL-1 remains unclear. Here, we find mechanistic interactions between working skeletal muscles and locally recruited neutrophils expressing IL-1β, which supports muscle performance through priming exercise-dependent GLUT4 translocation. Thus, during exercise, both IL-1α/β-deficient and neutrophil-depleted mice similarly exhibit increased fatigability associated with impaired muscle glucose homeostasis due to GLUT4 dysregulation. Deficiency of IL-1-producing neutrophils results in intrinsic abnormalities represented by aberrant Rac1 signaling and irregular GLUT4-storage vesicles, suggesting that these properties are maintained by local IL-1 produced by recruited neutrophils upon exercise, possibly on a daily basis. We propose that neutrophils are highly engaged in skeletal muscle performance via IL-1 regulation, which coordinates favorable inflammatory microenvironments supporting muscle glucose metabolism.

    Rotator cuff tears (RCTs) are a common shoulder problem in the elderly that can lead to both muscle atrophy and fatty infiltration due to less physical load. Satellite cells, quiescent cells under the basal lamina of skeletal muscle fibers, play a major role in muscle regeneration. However, the myogenic potency of human satellite cells in muscles with fatty infiltration is unclear due to the difficulty in isolating from small samples, and the mechanism of the progression of fatty infiltration has not been elucidated. The purpose of this study was to analyze the population of myogenic and adipogenic cells in disused supraspinatus (SSP) and intact subscapularis (SSC) muscles of the RCTs from the same patients using fluorescence-activated cell sorting. The microstructure of the muscle with fatty infiltration was observed as a whole mount condition under multi-photon microscopy. Myogenic differentiation potential and gene expression were evaluated in satellite cells. The results showed that the SSP muscle with greater fatty infiltration surrounded by collagen fibers compared with the SSC muscle under multi-photon microscopy. A positive correlation was observed between the ratio of muscle volume to fat volume and the ratio of myogenic precursor to adipogenic precursor. Although no difference was observed in the myogenic potential between the two groups in cell culture, satellite cells in the disused SSP muscle showed higher intrinsic myogenic gene expression than those in the intact SSC muscle. Our results indicate that satellite cells from the disused SSP retain sufficient potential of muscle growth despite the fatty infiltration.

    More details Close

    The time-controlled atmospheric pressure plasma flow is generated and irradiated to the living-cell suspended solution for clarifying the transfection mechanism toward developing highly-efficient and minimally-invasive gene transfection system. It is observed that the transfection efficiency is significantly increased by the short-time (< 4 sec) and short-distance (< 40 mm) plasma irradiation, and the high transfection efficiency of 53% is realized together with the high cell viability (> 90%). This result indicates that the physical stimulation such as the electric field caused by the charged particles arriving at the surface of the cell membrane, and chemical stimulation associated with plasma-activated products in solution act synergistically to enhance the cell-membrane transport with low-damage.

    The purpose of this study is to distinguish reactive species generated in gas-liquid interfacial plasmas by their lifetimes, to clarify the generation and extinction processes of "extremely short-lived reactive species", which react and self-dissolve in less than one second, and to experimentally clarify their effects on biomolecules and cells. The research was promoted by constructing an "atmospheric pressure plasma apparatus with high-speed liquid flow". As a result, we succeeded in the time-resolved measurement of extremely short-lived reactive species (OH radicals and nitrite precursors) in high-speed liquid flow for the first time, and constructed a reaction diffusion model that takes into account the surface localization distribution of OH radicals and consumption by long-lived reactive species. In addition, the effects of the extremely short-lived active species on biomolecules (amino acids) were also clarified.

    By establishing a novel intravital imaging system, we successfully revealed the importance of intramuscular paracrine/autocrine systems involving contracting myofibers, adjacent vascular endothelial cells and recruited neutrophils, which are triggered by muscle contractile activity and reliant upon CX3CL1/fractalkine-mediated signals. Specifically, the intravital imaging using transgenic mouse harboring skeletal muscle-specific GLUT4-EGFP expression and Quantum-dot-labelled neutrophils demonstrated that the fractalkine-mediated signals are required for both neutrophil accumulation and enhanced GLUT4 translocation in the working skeletal muscles. It is thus concluded that fractalkine is a key factor for organizing a neutrophil‐mediated favorable immunometabolic niche by orchestrating intramuscular vascular and immune responses in working skeletal muscles.

    This study aimed to establish an “in vitro exercise model” using human-derived muscle cells that often exhibit relatively poor contractile activity. By employing biomedical engineering techniques along with co-culture systems, we successfully established “in vitro exercise models” using (1) hybrid myotubes comprised of human myoblasts and murine C2C12 myoblasts as well as those using (2) murine 3T3L1 cells as a feeder for supporting development of human myotube contractile ability, that both exhibit vigorous contractile activity in response to electric pulse stimulation (EPS). Species-specific analyses allow us to separately evaluate contraction-inducible gene expressions and myokine secretions from human and mouse constituents. We also fabricated a culture insert chamber that one can efficiently deliver EPS to the myotubes. Thus, these inventions would allow us to maximize the use of the human myocytes obtained from biopsy samples, a very limited resource.

    Skeletal muscle regeneration after injury is a complex process involving inflammatory microenvironments. Interleukin (IL)-1 is a key mediator of inflammatory responses and exerts pleiotropic impacts on various cell types. Thus, we aimed to investigate the role of IL-1 during skeletal muscle regeneration. We herein show that IL-1KO mice exhibit delayed muscle regeneration characterized by delayed infiltrations of immune cells accompanied by suppressed local production of proinflammatory factors including IL-6 and delayed increase of satellite cells postinjury. Meanwhile, IL-1β secretion and NLRP3 inflammasome activation in macrophages produced mechanical hyperalgesia on over-exercised muscle pain. Taken together, we conclude that IL-1 plays a positive role in muscle regeneration, but also reduces over-exercised muscle pain.

    We have challenged to create “ultrasensitive cell-based sensor array” which can detect the temporal-spatial distribution of infinitesimal heterogeneous stimuli generated by the atmospheric pressure non-equilibrium plasmas. We measured the 2-dimensional distribution of oxidation stimulus (reactive species), electric stimulus (charged particles), pressure stimulus (shock wave) which were generated in the solution irradiated with atmospheric pressure plasma jet or in-liquid micro plasma. Furthermore, we arrayed the cells which have overexpressing channels responding with each stimulus, and measured the 2-dimentional distribution of fluorescence intensity proportional to the concentration of calcium ion or gene-simulated fluorescent molecule in the cells. As a result, we have demonstrated that the cells can act as the sensor arrays for oxidation stimulus, electric stimulus, and pressure stimulus.

    Rotator cuff tear is a common disease in elderly patients that leads to shoulder weakness, pain, and disability in the activities of daily living. Some patients with massive rotator cuff tears have an unacceptable clinical outcome because of muscle atrophy and fatty infiltration. The satellite cell has central role of muscle regeneration, however, there are few reports about human muscle. The purpose of this study was to compare in vivo features of human myogenic and adipogenic precursors in the rotator cuff muscles in both torn supraspinatus (SSP) and intact subscapularis (SSC) tendons. The human satellite cells from the SSP muscle with fatty infiltration maintained intrinsic myogenic potentials.

    Recently, non-equilibrium atmospheric pressure plasma (APP) emerged to exert diverse biological responses, though the underlying mechanisms remained to be determined. This study aimed to explore precise mechanisms underlying of plasma-inducible increases in intracellular Ca2+ concentration in insulin-responsive cells, which has been recently discovered by our research group. Our results demonstrated that increases in intracellular Ca2+ are induced by continuous low-dose O2-/ ONOO- supply, which is mediated through TRP channel activation. Our findings indicate the potential of APP for regulating insulin-responsive cell functions. Moreover, APP showed inhibitory actions on adipogenic differentiation of 3T3L1 cells. Together, these results demonstrate that APP-induced TRP channel activation is intimately involved in various cellular responses triggered by APP exposure.

    In order to develop a highly efficient and minimally invasive drug delivery method, the applications of plasmas generated in liquid to control of biological response have been proposed. In the beginning, it has been experimentally verified that micro-scale plasma was generated by applying a pulse voltage to coaxial type thin electrode and had the capability to enhance the cellular uptake of drugs and genes. Next, investigation of effects of separated plasma-derived stimuli on drug uptake showed that plasma-produced short-lived reactive species contribute to the drug uptake. Furthermore, it is clarified that relatively short-lived reactive species (i.e., deactivated within approximately 10 min) in plasma-irradiated saline induced physiologically relevant calcium ion influx through ion channel on cell membrane, which triggers activation of gene and drug uptake.

    This study attempted to develop a novel approach for quantifying intracellular vesicle trafficking dynamics utilizing Quantum-dot-based single molecule imaging in a isolated skeletal muscle fiber from mouse. Intracellular dynamics of GLUT4, an insulin-responsive glucose transporter, as well as of transferrin receptor (TfR) were successfully quantified with this novel approach. In addition, the superresolution G-STED microscopy was employed to observe intracellular vesicles and organelles containing GLUT4 and/or TfR.

    Physiological relevance of the Tripartite Complex Assembly composed of Vps10p/soluble ligands/GLUT4 was revealed by several experimental approaches including the single-molecule imaging analysis. Live-imaging analysis allowed us to visualize the transient formation of tripartite complex in a living cell and this approach successfully demonstrated that intracellular dynamics of the tripartite complex containing GLUT4 is tightly regulated by Tbc1d-family RabGAPs (AS160 and Tbc1d1).

    Defective insulin-responsive GLUT4 translocation is the earliest detectable feature of insulin resistance. Biochemical and nanometrological analyses herein revealed that sortilin, a member of the Vps10p-family sorting receptor, plays a critical role in establishing trans-Golgi network system specialized for generating the insulin-responsive GLUT4-strage vesicles that emerged to be severely deranged under certain insulin resistant conditions. This study thereby unmasks that insulin resistance is caused by not only defects in insulin signaling but also impairment of GLUT4 trafficking itself (“sorting disorder").

    There are many cells sensing mechanical forces in our body and the cells control the functions of tissues and organs to be adapted to mechanical environment. However, the mechanisms were not elucidated yet. In this study, we mainly focused on vascular endothelial cells, osteocytes and myocytes. It became clear that cell-cell and focal adhesions and cytoskeletons such as stress fiber are working as mechanosensors and some proteins in cytoplasm were identified as signal messengers. Mechanical forces were also playing important roles in organogenesis such as valve formation in cardiovascular system.

    Stress enhanced gut protective HSP70 expression at colon epithelia was found to be mediated both by TLR recognition of commensal bacteria and stress-induced glucocorticoid. Alternatively, stimulation of intestinal smooth muscle TLR reduces intestinal motility, and the absence of TLR stimulation by commensal bacteria greatly affects repair process of damaged skeletal muscle. Secondly, skeletal muscle cells per se were found to secrete cytokine IL-6 and chemokines CXCL1, 5 upon electrically stimulated contraction. Under reduced intracellular glycogen level, contracting myotubes effectively produces IL-6 depending on calcineurin activated NFATc1 translocation into nucleus. Muscle contraction induces production of CXCL5 mRNA in vivo, but CXCL5 protein was only detected when muscle damage was induced.

    本年度は、研究実施計画に基づき、伸展による培養筋細胞制御についての研究を行った。すなわち、培養筋細胞C2C12をシリコン膜上に播種し、分化させた後、ストレックス社製ストレッチ負荷装置を用いて伸展刺激を行い、細胞形態、細胞機能について解析を行った。まず、10%程度の伸展率でサイクリック伸展刺激を負荷することにより、ストレス応答性MAPキナーゼ、AMPキナーゼなどの酵素が活性化することがわかった。また、伸展刺激を付加することにより、以前申請者らが発見した運動に応答して筋からの分泌が促進される運動因子(CXCケモカイン群)の発現が促進されることが明らかとなった。さらに、伸展刺激負荷時にストレス応答性MAPキナーゼのひとつであるJNKの阻害剤を添加したところ、この運動因子の産生は完全に抑制されることも明らかとなった(Nedachi他、AJPEM, 2009)。2年間の研究成果をまとめると、継代可能な均質な培養筋細胞を用いて、高度発達型培養筋細胞系、擬似的運動刺激系、伸展刺激系の開発に成功した。これらのモデルは、生体筋でみられる運動効果やストレッチ効果を少なくとも一部再現しており、特に運動効果やストレッチ効果を正あるいは負に制御する新規物質の探索など、様々な分野に有用な生体材料・医用材料であることが強く示唆された。

    筋肉の主要なエネルギー源であるグルコースの取り込みに関わるGLUT4が、筋収縮活動やインスリンの刺激によってどのような分子挙動制御を受けるかについて、収縮能力を獲得した培養筋細胞と蛍光ナノ粒子(Qdot)を用いて1分子レベルで解析することを目的としている。 【計画】Qdotで標識可能なGLUT4分子(myc-GLUT4-ECFP)を恒常発現するマウスC2C12筋芽細胞を作製し、人為的な電気パルス刺激により収縮能力(サルコメア構造)を発達させることにより、本研究に最適化した条件を確立する。さらに、サルコメア構造の発達(有無)によりGLUT4分子挙動制御がどのように変化するのか調べることを目的とした。 【実績】サルコメア構造の発達した収縮型培養筋細胞を作製し、GLUT4分子をQdotにて特異的に標識することに成功した。独自に構築した共焦点顕微鏡を用いてGLUT4分子挙動を解析したところ、刺激のない状態ではGLUT4は何らかの機構により停留されており挙動が著しく制限されていた。一方、インスリンの刺激は、この停留機構を解除することにより、より活発に挙動できる分子群の総数を有意に増加させることが明らかとなった。この停留-解除の強度は、サルコメア構造の発達構築とともに変動することが観察されていることから、アクチン細胞骨格系の規則的な構築体がGLUT4の挙動制御に関与していることが示唆された。 【まとめ】生体筋では解析が難しかったGLUT4分子の挙動解析を、独自に開発した高度発達型の培養筋細胞を利用することによりはじめて可能した。筋構造の発達によりGLUT4の分子(およびGLUT4小胞)の挙動制御は大きく変化することが明らかとなった。

    蛍光ナノ粒子Q-dotで標識可能な遺伝子改変型GLUT4 (myc-GLUT4-ECFP)を恒常的に発現する培養脂肪細胞を用いて、Q-dotによりGLUT4分子を標識し、インスリン刺激に依存したGLUT4分子挙動の変化を1分子レベルで正確にとらえ生物物理学的に解析した。 共焦点顕微鏡を用いて、GLUT4貯蔵エンドソームからの運搬過程について、インスリンの効果と細胞分化に伴う変化を解析した。 【実績1】(1)インスリン刺激がないとGLUT4分子自体が「何らかの未知の機構」によりGLUT4貯蔵エンドソームに抑留されていること。(2)一方インスリン刺激により、活発に挙動するGLUT4分子(およびGLUT4含有小胞)が増加すること(GLUT4分子の抑留からの解放)。(3)そして、これらのGLUT4分子挙動制御系は細胞分化に伴い成熟していくこと(インスリン反応性ナノシステムの細胞分化に伴う成熟)をはじめて明らかにした。 全反射顕微鏡をもちいて、GLUT4小胞が最終的に膜融合する過程について、インスリンの効果を解析した。 【実績2】インスリンの刺激により、(1)GLUT4小胞の細胞膜への接近の確率が約3.75倍に増加すること、(2)さらに飛来したGLUT4小胞が細胞膜直下(あるいは細胞膜に)停留する時間が数倍に延長されることを明らかにした。これまでとらえることができなかった微細な生命反応(GLUT4分子挙動の制御)を最先端のナノ材料と視覚化技術により高精度で解析することに成功した。そして、インスリン受容体シグナルの作用点として、少なくとも2カ所(GLUT4貯蔵庫からの放出と開口放出前の繋ぎ止め過程)存在することをはじめて明らかにした。

    電気パルス刺激により培養筋細胞に収縮活動を負荷できる特殊培養系を作製し、代謝能の研究に適した高度発達型培養筋管細胞系を確立することを目的としている。昨年度までの成果をさらに発展させ、電気パルスにより誘導されるサルコメア構造の新規構築の分子機構と細胞内カルシウムの影響について基礎的な検討を行うことを本年度の目的とした。 【実績1】電気パルス刺激に完全に依存して細胞内カルシウム濃度が変動(Ca2+オシレーション)することを確認し、このCa2+オシレーションの周期(周波数)がサルコメア構造の新規構築に重要な役割を果たすことを明らかにした。さらに、Ca2+オシレーションにより、カルシウム依存性蛋白分解酵素であるカルパインの活性化が誘導され、このカルパインの活性化がサルコメア構造の新規構築に必須であることを明らかにした。この過程において、活性化されたカルパインは、細胞膜のIntegrinとアクチン細胞骨格を連結する役割を果たすTALINを分解すること、integrinを修飾するコラーゲン添加によりサルコメア構築が影響受けることから、筋管細胞の細胞接着班様領域を構成する蛋白複合体のCa2+-カルパイン依存性の分解と再構築が、新規サルコメア構造の形成に関与していることが示唆された。 【実績2】本特殊培養系で作製された収縮型培養筋管細胞では、収縮に伴い(1)エネルギー代謝の亢進(2)糖の取り込み亢進(3)インスリン反応性GLUT4膜移行の改善が確認され、生体に非常に近似な高度発達型培養細胞系を確立することに成功した。

    細胞増殖にはカルシウムイオンの流入が増加することが必須で,これが抑制されると増殖因子はその増殖促進作用を発揮することが出来ない。細胞周期を進行させるプログレッション因子はカルシウム透過性チャネルを活性化して持続的なカルシウム流入増加を惹起するが,そのチャネルの分子実体はこれまでまったく明らかではなかった。本研究ではPCRを用いたクローニング法によりインスリン様成長因子(IGF-I)によって活性化されるカルシウム透過性チャネルの遺伝子クローニングを行いそのチャネルの調節機構について検討を行った。クローニングされたチャネルGRC(growth factor-regulated channel)は756個のアミノ酸からなる膜貫通蛋白で,疎水性の検討から6個の膜貫通部位を持つものと推定された。 その一次構造はTRPに類似し,とくにVR-1とはアミノ酸レベルで40%の相同性を示した。GRCをCHO細胞に発現させるとカルシウム透過性チャネルとして機能した。生理的なカルシウムが存在する場合には,このチャネルは主にカルシウムなど二価陽イオンを透過した。GRCは非刺激時には細胞内プールに存在するが,IGF-Iにより細胞膜上にトランスローケーションした。IGF-Iを除去するとGRCチャネルは再びエンドサイトーシスにより細胞内プールにもどった。このようにGRCチャネルはその細胞内局在が変化することによって調節されるというまったく新しい調節機構をもっていた。

    昨年度の検討により、マウス胸腺cDNAライブラリーから新規チャネル様蛋白の遺伝子の単離に成功し、その機能解析を遺伝子工学的、電気生理学的手法を用いて行った。 この遺伝子は全長2268bpで、アミノ酸756残基からなり細胞膜を6回貫通する新規チャネル様蛋白をコードしていた。trp familyに属するカプサイシン受容体(VRl)と約43%の相同性が認められた。ノーザン解析により種々の組織でその発現が認められ、特に胸腺、肺、脳で強く発現していた。発現ベクターにcDNAを組み込みCHO細胞などに強制発現させたところ、インスリン様成長因子-1(IGF-I)に反応し細胞内カルシウム濃度が著明に増加した。C末端に対する抗体を作製し細胞内における局在、各組織におけるこの蛋白の発現についても検討した。IGF-I刺激によりこのチャネル蛋白の細胞内から細胞膜上へのトランスローケションが惹起されることが免疫染色により確認された。。電気生理学的検討から、IGF-Iで前処理した強制発現細胞では陽イオンの透過性が大きく増加しており、このチャネル蛋白がnon-selective Ca2+透過性チャネルとして機能することが確認された。 結論:増殖因子作動性の新規カルシウム透過性チャネルを同定した。

    Augmentation of liver regeneration, with an artificial support to maintain liver function necessary for survival, would be beneficial for the treatment of fulminant hepatic failure caused by viral infection and hepatic toxins. As well, massive hepatectomy to resect liver tumors can be performed safely if the growth of the remnant liver is promoted effectively. Recently, the roles of various growth factors in the regulation of hepatocyte growth have been elucidated. Activin A which belongs to the transforming growth factor beta super gene family is a potent autocrine growth inhibitor in hepatocytes. Activin A is induced in vivo after partial hepatectomy. Low levels of the messenger RNA for the betaA-subunit of activin are markedly increased 20 hours after hepatectomy. When follistatin, which binds activin and blocks its action, is infused into the portal vein immediately after hepatectomy of 70%, DNA is synthesized several hours earlier than in control rats and liver regeneration is significantly augmented. Follistatin provides a potential therapeutic approach to promoting liver regeneration because it specifically blocks autocrine growth inhibitor. The results were reported in Gastroenterology (vol 108 : 1136-1142,1195). Then, we obtained the results that the intravenous administration of follistatin effectively promoted liver regeneration after partial hepatectomy. These were reported in Hepatology (vol : 24 : 361-366,1996). We then investigated the effects of follistation on liver regeneration under more critical condition, 90% hepatectomy in rats and obtained the results that follistatin was quite effective in promothing liver regeneration. In this project we made four kinds of analog follistatin to select the amino acid sequence which were expected to express the effects of follistatin (1.heparin binding side, 2.3.follistatin module, 4.c-terminal), and made two types of follistatin which were constructed with 288 and 315 of amino acids. We are investigating the effects of these analog follistatins on liver regeneration.

    増殖因子の作用発現においてカルシウムイオンは必須の役割を果たしているが,その流入経路すなわちカルシウムチャネルの本体は不明で,その活性調節機構も明らかでない.本研究では細胞増殖に関与することが確かめられたカルシウムチャネル分子CD20を遺伝子導入により過剰発現させたBalb/c3T3細胞を作製し,今まで解析が困難であった増殖因子受容体によるチャネル活性化の分子機構を分子生物学的および電気生理学的手法を用いて明らかにすることを目的とした. その結果,CD20チャネルはインスリン様増殖因子-1(IGF-1)によって活性化されそのカルシウム透過性が亢進するが百日咳毒素(PTX)処理によりこのIGF-1の活性化作用は完全に消失すること,一方GTP結合蛋白を直接的に活性化するマストパランやconstitutively active G蛋白変異体であるGip2の共発現によりこのチャネルが強く活性化されることなどから,CD20がPTX感受性GTP結合蛋白を介して活性化されていることを明らかにした(Kanzaki et al. J.Biol. Chem. 272:4964-4969).またIGF-1によるCD20チャネルの活性化には細胞内にGTP,Mg2+に加えATPが必要であるが,一方GTP結合蛋白を直接活性化するマストパランやconstitutively active変異体Gip2の共発現によるCD20の活性化にはATPは必要でなかった.これらのことからATPはIGF-1受容体がGTP結合蛋白を活性化するステップに重要であることを明らかにした.またこのATPは非水解性ATPアナログであるAMP-PNPによって置き換えることができることから蛋白のリン酸化は関与しないと考えられた(投稿中).
