This study found that NK and CD8+ T cell infiltration may drive inflammation in androgenetic alopecia, suggesting that targeting IL-15 signaling could offer a new therapeutic approach for hair regeneration.

This study found that toll-like receptor 9 plays a previously unrecognized role in sensing skin injury and influencing tissue repair and regeneration in adult mice by modulating γδT cell migration.

Mindfulness reduces anxiety and depression in skin disease patients; dermatologists and psychiatrists often lack confidence in treating psychodermatological conditions.

This study found that selectively targeting HDAC4 and HDAC7 in mice can reduce Th17 cell-mediated intestinal inflammation, suggesting a potential treatment approach for Th17-related inflammatory diseases like ulcerative colitis.

This review discusses the genetic, autoinflammatory, and keratinization factors involved in hidradenitis suppurativa and presents the concept of classifying it as an autoinflammatory keratinization disease, but reports no new clinical results.

This study found that MDSC exosomes promoted partial hair regrowth and modulated immune responses in mice with alopecia areata, suggesting potential as a treatment for autoimmune diseases.

The conclusion is that CD90 is not a specific marker for fibroblast subtypes and better methods are needed to identify them.

This study, using multimodal profiling in mice, found that various tissues contain unique γδ T cell subsets adapted to their environment, revealing their functional diversity, lineage relationships, and similarities to CD8+ tissue-resident memory T cells.

This review discusses the hedgehog signaling pathway's role in cutaneous tumors and hematological disorders, highlighting its potential as a therapeutic target, but reports no new clinical findings.

This article offers a viewpoint on hidradenitis suppurativa pathogenesis, suggesting that impaired Notch signalling from γ-secretase mutations may drive inflammation and link the condition to other Th17-driven diseases.

This review summarizes existing evidence on the efficacy and safety of JAK inhibitors for treating alopecia areata and emphasizes the need for improved topical formulations.

This manuscript reviews the latest understanding of alopecia areata's pathogenesis, highlighting the roles of genetic, immunological, and environmental factors, with a focus on immune responses involving IFN-γ and cytotoxic CD8+ T-cells as key contributors to hair follicle inflammation and function disruption without follicle destruction.

This study found that certain T cell-associated genes were upregulated in dogs with Vogt-Koyanagi-Harada syndrome and vitiligo, suggesting a shared immunopathogenesis with humans.

This review analyzed literature on primary cutaneous lymphomas involving the scalp, finding that scalp involvement in these cases often leads to non-scarring focal alopecia and may indicate more aggressive disease.

This narrative review explored the complex interconnections between psoriasis and other dermatological conditions like vitiligo, alopecia areata, and atopic dermatitis, highlighting shared immune dysfunctions that complicate diagnosis and treatment, with implications for research and holistic patient care.

This study suggests that low-dose IL-2 and IL-15 may help restore immune tolerance in alopecia areata by maintaining Treg cell function, presenting a potential new treatment strategy.

This study found that D-peptide crosslinked MAP hydrogel accelerated material degradation in vivo but significantly enhanced skin regeneration, suggesting an adaptive immune response can drive regenerative healing even with rapid scaffold breakdown.

This study found that pediatric alopecia areata patients with atopic predisposition showed heightened immune and inflammatory responses, including significant immune cell infiltration, compared to adults and healthy controls.

The study investigated immune cell patterns around the hair follicle infundibulum in androgenetic alopecia, revealing significant differences in immune signatures between patients with AGA and control donors, specifically noting an enrichment of CD4 cells in the patient group.

This study suggests that MUC1 expression is significantly higher in follicular mucinoses compared to other dermal mucinoses, particularly in lymphoma-associated forms, indicating its potential as a target for immunotherapy.

This study identified four hub genes that are closely linked to the causative factors of androgenetic alopecia, suggesting potential diagnostic and therapeutic targets.

This study found that individuals with AA have a higher incidence of atopic and autoimmune conditions, suggesting both Th1 and Th2 immune responses may play a role in its development.

This article hypothesizes that thymoma with aplastic anemia may result from abnormal autoimmune CD8⁺ T lymphocytes produced by the thymoma, potentially leading to other cytotoxic T-cell-mediated autoimmune diseases.

This study found significant gene expression abnormalities in hair follicles affected by alopecia areata, suggesting persistent changes that may predispose to future relapses even after hair regrowth.

This report describes two cases of folliculotropic mycosis fungoides with syringotropism, highlighting indolent progression despite the disease's typically aggressive nature, suggesting aggressive treatment might not be necessary.

In this study, increased Treg cell activity indicated by IL-10 and IL-15 was identified as a feature of ADTA, distinguishing it from AA and potentially explaining ADTA's more favorable prognosis.

This study suggests that allogenic human mesenchymal stem cell treatments have potential therapeutic effects by inducing immune tolerance and anti-inflammatory effects in severe alopecia areata patients.

This study found that CD45RO+ cells, a subtype of T lymphocytes, were notably reduced in the ovarian follicles of women with PCOS, which may contribute to the condition's pathogenesis.

This review discusses the insights gained from single-cell RNA sequencing of fibroblasts in various cancers and wound healing, highlighting differences in gene expression and novel interactions.

This study provides a detailed cellular atlas of cutaneous squamous cell carcinoma, indicating that different fibroblast subtypes play roles in tumor progression and suppression, with potential biomarkers identified for HPV-related tumor growth.
