    Baricitinib, a Janus kinase inhibitor, demonstrated efficacy in achieving scalp hair regrowth in severe alopecia areata (AA). While short-term real-world data on its efficacy have been reported, long-term data remain limited. This retrospective observational study spanning 104 weeks analyzed clinical trajectories of 51 severe AA patients treated with baricitinib. Among them, 36 continued treatment for 104 weeks, with 55.6% achieving a SALT score of ≤ 20 and 72.2% achieving ≥ 30% improvement from baseline in SALT score (SALT30). Multivariate analysis identified female sex and disease duration < 4 years as significant predictors of response. Furthermore, patients with eyebrow or eyelash regrowth at 52 weeks had a higher likelihood of achieving long-term scalp hair regrowth. We identified a subgroup of markedly slow responders who achieved SALT30 between 52 and 104 weeks, many of whom had eyebrow or eyelash regrowth at 52 weeks. Baricitinib was well tolerated throughout the study period, with no serious long-term adverse effects. Our findings supported baricitinib's long-term efficacy and safety and suggested predictive factors for treatment responses in severe AA.

    Alopecia areata (AA) is a chronic, autoimmune skin disease characterized by non-scarring hair loss. Baricitinib, a Janus kinase inhibitor (JAKi), prevents hair loss and promotes hair regrowth by inhibiting the inflammatory Janus kinase-signal transducer and activator of transcription (JAK-STAT) signaling pathway involved in cytotoxic T cell responses targeting hair follicles. The introduction of JAKi has transformed treatment against severe AA. However, treatment responses to JAKi are highly variable among patients, and the predictors of responsiveness remain insufficiently elucidated. This study aimed to identify independent predictive factors for the efficacy of baricitinib in patients with severe AA using multivariate analyses. A retrospective study was conducted on 70 severe AA patients who started baricitinib treatment at Tohoku University Hospital between July 2022 and August 2023. The primary outcome was the percentage of patients achieving a Severity of Alopecia Tool (SALT) score of ≤20 after 9 months of baricitinib treatment. Multivariate analysis assessed potential predictors of baricitinib treatment responses, including AA type, sex, age, disease duration, history of atopic dermatitis, intravenous methylprednisolone pulse (IVMP) therapy, and Clinician-Reported Outcome (ClinRO) measures for eyebrows and eyelashes. Achievement of a SALT score of ≤20 and SALT score improvement rates were used as objective variables in the multivariate analyses. Among the 70 patients completing 9 months of baricitinib treatment, 41% achieved a SALT score of ≤20. Multivariate analyses identified several independent predictors for positive outcomes, including shorter disease duration (≤4 years), history of IVMP, therapy SALT score of ≤95 at baricitinib initiation, and female sex. Further, we found differential response patterns based on AA type and sex. Specifically, AA type significantly influenced treatment responses, with ophiasis alopecia (OA) associated with the poorest improvement rate. In summary, the response to baricitinib in AA is significantly influenced by sex, AA type, disease duration, history of IVMP, and pre-treatment SALT score.

    Systemic sclerosis (SSc) is characterised by immune dysregulation, vasculopathy and fibrosis, driven by genetic and environmental factors. S100 proteins, which constitute a unique class of calcium-binding proteins, have been shown to be critically implicated in various inflammatory and fibrotic conditions. In this study, we investigated the possible involvement of S100A11 in SSc by examining its cutaneous expression and systemic serum levels, correlating them with key clinical parameters. First, we performed immunohistochemical (IHC) staining to examine S100A11 localisation in skin specimens from SSc patients and controls, and found that S100A11 was robustly expressed in SSc dermal fibroblasts. Analysis on the publicly available single-cell RNA-sequencing (scRNA-seq) data of SSc skin samples further confirmed that S100A11 was highly expressed in SSc dermal fibroblasts along with several key genes associated with cellular senescence. Finally, we evaluated serum levels of S100A11 in SSc patients and HCs using enzyme-linked immunosorbent assay (ELISA), and found that serum S100A11 levels were significantly elevated in diffuse cutaneous SSc (dcSSc) patients compared to controls. S100A11 serum levels in SSc patients were significantly correlated with modified Rodnan total skin thickness score and key parameters of SSc-related interstitial lung disease. Our data collectively suggested a potential pathophysiological role of S100A11 in the cutaneous and lung fibrosis associated with SSc, warranting further investigation into its functional roles in this disease.

    An active form of cathelicidin antimicrobial peptide, LL-37, has immunomodulatory and stimulatory effects, though the specific pathways are not clear. The purpose of this study was to identify the cellular pathways by which LL-37 amplifies the inflammation induced by damage-associated molecular patterns (DAMPs). We performed DNA microarray, reverse transcription polymerase chain reaction, immunoblotting, and proximity ligation assays using cultured keratinocytes treated with LL-37 and/or the DAMP poly(I:C), a synthetic double-stranded RNA. In contrast to the combination of LL-37 and poly(I:C), LL-37 alone induced genes related to biological metabolic processes such as VEGFA and PTGS2 (COX-2). Inhibition of FPR2, a known receptor for cathelicidin, partially suppressed the induction of VEGFA and PTGS2. Importantly, VEGFA and PTGS2 induced by LL-37 alone were diminished by the knockdown of scavenger receptors including SCARB1 (SR-B1), OLR1 (SR-E1), and AGER (SR-J1). Moreover, LL-37 alone, as well as the combination of LL-37 and poly(I:C), showed proximity to the scavenger receptors, indicating that LL-37 acts via scavenger receptors and intermediates between them and poly(I:C). These results showed that the broad function of cathelicidin is generally dependent on scavenger receptors. Therefore, inhibitors of scavenger receptors or non-functional mock cathelicidin peptides may serve as new anti-inflammatory and immunosuppressive agents.

    Psoriasis is a chronic disease centered on tumor necrosis factor (TNF), interleukin (IL)-23, and IL-17 axis. While psoriasis patients benefit from biologics targeting TNF, IL-17s, and IL-23 nowadays, suppression of these molecules could modulate the balances of immune systems. However, the incidence of autoimmune disease and T-helper 2 reaction during biologic treatments for psoriasis patients is not well documented. We retrospectively examined antinuclear antibody (ANA), eosinophil counts, and immunoglobulin E (IgE) levels for psoriasis patients who underwent biologic treatments in our dermatology clinic from June 10, 2010 to January 29, 2020. A cumulative total of 199 biologic treatments were performed for a total of 128 psoriasis patients. Compared to the non-biologic group of 109 psoriasis patients who received non-biologic treatment, patients treated with infliximab showed more incidents of high ANA (14%, p = 0.039) and high eosinophils (14%, p = 0.021). The use of brodalumab increased incidents of high eosinophils (21%, p = 0.005) but did not affect increase in ANA and IgE. The increase in high IgE level was observed significantly more during the use of risankizumab (15%, p = 0.011). Methotrexate was the most frequently used concomitant systemic treatment, but methotrexate did not affect ANA, eosinophil counts, and IgE levels. Since the biologics for psoriasis treatment modulate the balance of T-helper cells, careful observation is required to detect unexpected changes of systemic immune conditions under biologic treatments.

    Biologics has had a great impact on psoriasis treatment as well as the life of psoriasis patients. Infliximab (IFX), one of the biologics targeting tumor necrosis factor (TNF), is the first of the biologics introduced to Japanese psoriasis patients. Many patients had benefits of IFX from initial applications and sustained remission of skin lesions and arthritis. Some, however, fall into so-called secondary failure, in which patients become less responsive to IFX when the treatment is repeated. The mechanism of secondary failure and the background of patients with secondary failure have not been completely elucidated. To address this issue, we retrospectively evaluated psoriasis patients treated with IFX in our department. In this retrospective, single-center, case-control study based on the clinical record, a total of 34 patients were enrolled. We excluded 7 patients who discontinued IFX because of adverse events of IFX. We divided other 27 patients into two groups; 16 patients who kept using IFX (Continuance group); and 11 patients who switched to other treatments (Discontinuance group). Among various clinical features, body mass index (BMI), HbA1c, and serum CRP level were significantly higher in the Discontinuance group than the Continuance group. The results indicated that these three clinical features of BMI, HbA1c and serum CRP level before treatment are the predictors of successful IFX treatment and suggest that improvement of metabolic conditions contributes to avoiding secondary failure and discontinuance of IFX.

    We have reported that the IL-2 Luc assay can detect the effects of chemicals on IL-2 promoter activity by using a dual reporter cell line, 2H4 cells that measure IL-2 promoter-driven luciferase activity (IL2LA) and GAPDH promoter-driven luciferase activity (GAPLA). Since the IL-2 Luc assay cannot detect immunosuppressive drugs that are antimitotic towards rapidly proliferating cells, we attempted to establish a new assay to detect these chemicals by taking advantage of the dual reporter cell properties of 2H4 cells. We first determined the optimal incubation time with drugs and the seeding cell density, and confirmed that the change in GAPLA and IL2LA levels reflects the change in cell count and IL-2 production of 2H4 cells after drug treatment. We designed the IL-2 luciferase lymphotoxicity test (IL-2 Luc LTT) to detect the antimitotic effects of chemicals by modifying the protocol and criteria of the IL-2 Luc assay. To determine the performance of the IL-2 Luc LTT and that of the combination of the IL-2 Luc LTT and the IL-2 Luc assay, we examined 46 drugs: 19 immunosuppressive drugs with different mechanisms of action, 12 anti-cancer drugs, and 15 non-immunosuppressive drugs. The performances of the IL-2 Luc LTT, the IL-2 Luc assay and their combination were 43.3%, 61.3%, and 93.3%, respectively, for sensitivity, 84.6%, 53.3%, and 50.0%, respectively, for specificity, and 55.8%, 58.7%, and 79.5%, respectively, for accuracy. These results demonstrated that the combination of these two assays is promising for the detection of immunosuppressive drugs with different mechanisms of action.

    A 66-year-old man with a 2-year history of suspected scalp eczema with excessive dandruff developed painful swollen joints in the extremities. Four months after developing polyarthritis and polydactylitis, eczema gradually spread to the face. He was referred to our hospital for intractable scalp and facial eczema and polyarthritis. Based on the appearance of the head and facial skin lesions, psoriasis was suspected. Treatment with apremilast (a phosphodiesterase-4-inhibitor) was initiated, which swiftly alleviated the skin lesions. The joint deformities persisted, but the pain in the joints disappeared. This case implies that psoriatic arthritis should be suspected even if psoriatic skin lesions are localized to the scalp.

    Psoriasis is a systemic inflammatory disease caused by crosstalk between various cells such as T cells, neutrophils, dendritic cells, and keratinocytes. Antimicrobial peptides (AMPs) such as β-defensin, S100, and cathelicidin are secreted from these cells and activate the innate immune system through various mechanisms to induce inflammation, thus participating in the pathogenesis of psoriasis. In particular, these antimicrobial peptides enhance the binding of damage-associated molecular patterns such as self-DNA and self-RNA to their receptors and promote the secretion of interferon from activated plasmacytoid dendritic cells and keratinocytes to promote inflammation in psoriasis. Neutrophil extracellular traps (NETs), complexes of self-DNA and proteins including LL-37 released from neutrophils in psoriatic skin, induce Th17. Activated myeloid dendritic cells secrete a mass of inflammatory cytokines such as IL-12 and IL-23 in psoriasis, which is indispensable for the proliferation and survival of T cells that produce IL-17. AMPs enhance the production of some of Th17 and Th1 cytokines and modulate receptors and cellular signaling in psoriasis. Inflammation induced by DAMPs, including self-DNA and RNA released due to microinjuries or scratches, and the enhanced recognition of DAMPs by AMPs, may be involved in the mechanism underlying the Köbner phenomenon in psoriasis.

    代表的なDamage-associated molecular patterns (DAMPs)を抗菌ペプチドLL-37とともにヒト培養角化細胞に加えたところ、乾癬の病態形成に重要な炎症性サイトカインが誘導された。またこれらの誘導は、スカベンジャー受容体(SR)の阻害により抑制された。これはLL-37がこれらのDAMPsと結合し、SRから細胞内に取り込まれ、炎症を誘導することを示す。 また、乾癬患者皮疹部の組織標本を用いた免疫染色では、真皮にLL-37陽性細胞がみられる症例でのみ、表皮でIL-36γが観察され、生体内でLL-37により表皮角化細胞からのIL-36γ産生が促される可能性が示された。

    代表的なDamage-associated molecular patterns (DAMPs)であり、スカベンジャー受容体のリガンドとして知られるmock dsDNAやhigh mobility groupbox 1 proteinを活性型カセリサイディン(LL-37)とともにヒト培養角化細胞に加えたところ,単独に比べIL-6,TNF-αといったサイトカインが強く誘導された.また,乾癬患者病変部皮膚を用いた免疫組織化学法では、LL-37陽性角化細胞を多数認める症例でのみ,乾癬の病態形成に重要であるとされるIL-36γが表皮で陽性だった。

    血管肉腫組織におけるmTOR経路とオートファジー機構関連分子の発現確認を免疫組織学的に検討した。mTOR経路関連分子では、血管肉腫において、mTORの発現増強を確認し、PI3K, AKT, TSC1, TSC2の発現が血管肉腫組織内に確認された。オートファジー経路関連分子では、ATG14とATG8 (LC3-I/LC3-III)の発現が増強している血管肉腫組織を確認した。発現は組織辺縁に強く、組織中央部においてはATG8 (LC3-I/LC3-III)の発現は乏しかった。これらの結果は、細胞増殖・分裂が多く起こっている腫瘍辺縁の領域においてオートファジー径路が働いている可能性を示唆した。 血管内皮細胞を用いたmTOR経路とオートファジー機構関連分子の強発現・抑制による細胞動向の検討を行った。オートファジー経路の抑制化合物を添加した後に細胞増殖をMTT法にて検討したところ、血管内皮細胞の細胞死の比率が高くなったことが確認された。すなわち、オートファジー径路は血管内皮細胞の増殖維持に正に働き、その抑制は細胞死を誘導することを示唆した。また、オートファジー経路の抑制化合物を添加した条件下では、mTOR経路関連分子とオートファジー機構関連分子の遺伝子発現が誘導されていた。以上のことから血管系細胞では、mTOR経路関連分子とオートファジー機構関連分子が、腫瘍組織・細胞の増殖に関連しており、mTOR経路関連分子とオートファジー機構関連分子のフィードバック機構の存在が想起された。

    オートファジー関連分子であるLC3Bの表皮、皮膚付属器への発現が確認された。また乾癬やアトピー性皮膚炎といった疾患において、表皮顆粒層でのLC3Bの発現がより強くみられ、表皮肥厚による顆粒合成の亢進を反映していると考えた。またヒト培養表皮角化細胞を用いた実験では、LC3Bについて、TLR9リガンドで細胞を刺激した際に発現が増強する傾向が見られた。 これらの結果は、オートファジーが皮膚での様々な物質合成に関与すること、細菌感染によりオートファジー及びそれに続く表皮過形成が誘導されることを示唆するものであるが、その機序を明らかにするには至らなかった。

    本研究の目的は今なお予後不良な疾患である血管肉腫の分子病態機構を調べることとし、そのなかでもmTOR経路とオートファジー機構の関与を調べることを主目的とする。平成24年度は、血管肉腫組織での関連分子の発現を免疫組織学的に検討したところ、正常血管内皮に比して強発現していることを確認し、特にオートファジー系経路が恒常的に活性化されていることが示唆された。血管肉腫細胞の培養系では、mTOR経路の阻害剤とオートファジー阻害剤を用いたところ、腫瘍細胞のアポトーシス誘導が確認できた。平成25年度は正常皮膚での両経路の発現を確認した。これらの結果は両経路の阻害が血管肉腫の新たな治療になる可能性を示唆した。
