This study used electron microscopy to identify a distinct dendritic cell in the human epidermis, similar to the melanocyte, with unique structural features and variable melanin content.

This study found that TNC + fibroblasts are crucial in neuro-immune interactions in various skin diseases, particularly inflammation and tumors, by engaging extensively with immune cells and overexpressing inflammatory genes, suggesting their significant role in skin abnormalities.

This study found that acne lesions and nonlesional skin in mild-to-moderate acne patients showed significant Th17-skewing and increased antimicrobials, suggesting systemic targets like IL-17/IL-23/IL-36 could be therapeutic.

This study found that C8/144B antibody exclusively binds to the hair follicle bulge and not the epidermal stratum basale, with cytokeratin 19 serving as a key marker of certain basal keratinocytes that decrease with age.

This study identified elevated CD25 on secreting CD4 regulatory T cells as a genetic risk factor for androgenetic alopecia, with certain plasma proteins acting as mediators in this causal relationship.

This study concluded that myositis in the reported case was caused by T-cell large granular lymphocytic leukemia, not dermatomyositis.

This review outlines the transition from simple hair follicle organoids to immune-competent microphysiological systems, addressing limitations in replicating native hair follicle immune features and discussing their applications in disease modeling and regenerative medicine.

This study describes vitiligo as an autoimmune disease marked by depigmented skin and mucosal patches, and reviews its complex pathogenesis and diagnostic features. Treatment aims for disease control and repigmentation through various topical and systemic therapies, phototherapy, and surgical options, emphasizing personalized, multimodal approaches.

This review highlights the promising potential of using nanomedicine-based immunotherapy in tissue regeneration, detailing recent advances in nanocomposite biomaterials and the modulation of immune responses to create optimal environments for tissue repair.

This study found that a spontaneous deletion in the Dsg3 gene of mice leads to hypomorphic desmoglein 3 expression, resulting in severe immunodeficiency, cyclic hair loss, and wasting disease, without causing the blistering typical of pemphigus vulgaris.

This study identified specific markers that can distinguish between stem cells in different regions of human scalp hair follicles, offering potential strategies for cell sorting and purification based on these markers.

Alopecia areata patients have more activated T cells in their blood, which may help in developing treatments.

This article discusses adverse immune-mediated skin reactions associated with TNF-alpha inhibitors, highlighting paradoxical reactions such as psoriasis that occur despite being treated with medications intended to alleviate the condition.

This study identified a distinct cytokine activation signature in alopecia areata, involving TH2, TH1, IL-23, and IL-9/TH9 pathways, suggesting potential targeting strategies similar to those in psoriasis and atopic dermatitis.

This review discusses the heterogeneity of Tregs in normal and tumor environments, emphasizing the complexity of targeting tumor-resident Tregs while maintaining systemic immune tolerance, but reports no new findings.

This review discusses how recent studies use models and experiments to understand immune system signaling, but it reports no new clinical findings; the authors suggest strategies for improving these models.

This study reviews potential immune targets within hair follicles in alopecia areata, suggesting they may be associated with keratinocytes or melanocytes, and notes possible induction triggers like viruses and infections.

This review highlights recent insights into how IL-15 influences T cell responses and contributes to immunopathogenesis in various diseases, suggesting its crucial role in TCR-independent activation and potential in optimizing therapeutic strategies.

In this study, TRPV3G568V mice exhibited periodic hair loss and immune cell infiltration in the dermis, without affecting hair follicle stem cell fate, suggesting a focus on dermal immune cells for future research.

This case study suggests that atrichia with papular lesions associated with common variable immunodeficiency may follow an autosomal-dominant inheritance pattern, differing from previous reports of autosomal recessive inheritance.

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, trichocytes were shown to have potential for alternative differentiation, with mesenchymal cell influences playing a critical role in determining this process.

This review discusses recent findings on the mechanisms driving bullous pemphigoid, highlighting epitope spreading and the roles of regulatory T cells, and reports no new experimental results.

This study found that onychomatricoma can fully mimic the nail unit and differentiate toward the nail bed and isthmus, distinguishing it from other pilar tumors.

In a preclinical mouse model, this study found that early treatment with the selective SYK inhibitor entospletinib significantly improved survival rates and clinical outcomes for graft-versus-host disease after hematopoietic stem cell transplantation compared to placebo.

This study found that patients with alopecia areata receiving combined therapy showed a significant reduction in proinflammatory cytokines and circulating immune complexes, along with increased IL-10 levels and phagocytic activity, suggesting an immunomodulatory effect that reduces inflammation and restores immune balance.

In this open-label trial, Tofacitinib was well tolerated and improved IFN and cytokine scores, as well as overall skin pathology, in individuals with Down syndrome and immune skin conditions.

This study found that DPCP immunotherapy effectively treats alopecia areata, identifying factors that influence treatment response and patient satisfaction, which may aid in standardizing the treatment for improved outcomes.

In this case report, a girl with autoimmune polyglandular syndrome type 1 experienced stabilized disease and reversal of alopecia universalis after treatment with glucocorticoids and methotrexate.
