This case report describes a 77-year-old woman with female pattern hair loss and elevated testosterone levels, who showed no improvement with minoxidil and lacked adrenal tumors on imaging.

This study found that testosterone and dihydrotestosterone can induce growth factors from dermal fibroblasts, promoting keratinocyte proliferation and differentiation, which may contribute to sex hormone-related acne development.

In this study, researchers identified IL18R+ thymus-resident regulatory T cells in mice, demonstrating their unique molecular features and resistance to age- and stress-induced thymus involution, highlighting IL18 signaling's role in Treg migration and retention.

OR101 may effectively treat atopic dermatitis and similar skin conditions.

This review highlights the possible role of T regulatory cells in the immune-related mechanisms of alopecia areata but reports no new clinical findings.

This study reported that IL-15 promotes human hair growth and protects hair follicle immune privilege, potentially stabilizing alopecia areata treatment outcomes when selectively stimulating IL-15Rα signaling.

This review discusses the role of the long form of thymic stromal lymphopoietin in cutaneous immune-mediated diseases and reports no new results.

OX40-targeted therapies may help treat skin diseases by reducing inflammation and balancing immune responses.

In ex vivo organ culture of human scalp hair follicles, this study found that IL-9 signaling inhibits hair growth, reduces progenitor cell generation, and disrupts immune privilege.

This review discusses the role of regulatory T cells in skin, including their impact on hair follicle regeneration, wound healing, and immune tolerance, without presenting new clinical findings.

This study found that H-Ras activation in aged mouse skin leads to increased dysplasia and progression to in situ squamous cell carcinoma, highlighting an age-linked connection between immune changes, senescence, and cancer risk.

This study found that deleting Stim1 and Stim2 in mature T regulatory cells disrupts Ca 2+ signaling, preventing their differentiation and leading to severe autoimmune disorders in mice.

In this study, researchers using a Treg-specific HuR-deficient mouse model found that the RNA-binding protein HuR is crucial for stabilizing Foxp3 mRNA, affecting Treg function and immune regulation, with HuR disruption leading to impaired Foxp3 expression and potential autoimmune dysfunction.

The congress showed that psychological therapy can help skin condition patients, social media affects acne stigma, education improves atopic dermatitis, and patient satisfaction in dermatology is high, especially with good doctor engagement.

Different cells affect hair follicle blood vessels, endothelial cells react differently to inflammation and oxidized fats, and prasugrel better protects heart vessels during a procedure than clopidogrel.

Prasugrel is better than clopidogrel at preventing heart damage and improving blood flow in small heart vessels during heart artery procedures.

This study found a direct correlation between IL6 and insulin, glucose, and cholesterol serum levels in patients with oral lichen planus, suggesting a potential increased cardiovascular risk.

This study reports that CD200R expression is significantly reduced in a mouse model of scarring alopecia, suggesting a potential role for this pathway in immune regulation and hair follicle protection.

This study found that PX-12 inhibited the NLRP3 inflammasome and reduced psoriasis-like symptoms in a mouse model, suggesting its potential as a treatment for psoriasis.

This study found that the IL-33/ST2 axis may protect against skin carcinogenesis by promoting cross-talk between epithelial cells and regulatory T cells to minimize mutations and contain tissue damage.

This study suggests that rather than inhibiting IL-15, selectively stimulating IL-15Ra-mediated signaling could be beneficial for managing alopecia areata and possibly other inflammatory hair loss conditions, as IL-15 promoted hair growth and maintained immune privilege in human hair follicles.

This study found that IL-6 knockout mice exhibited increased wound-induced hair neogenesis compared to wild-type mice, likely due to enhanced STAT3 activation facilitated by compensatory cytokine activity.

This study found that RNase L acts as a regeneration repressor gene in mammals, as seen in Rnasel-/- mice which showed increased regenerative capacity and elevated Wound Induced Hair Neogenesis through enhanced IL-36α signaling, suggesting a tradeoff between regeneration and immune regulation.

This study reviewed recent theories on alopecia areata's pathogenesis, highlighting its autoimmune nature due to immune privilege disruption in hair follicles, and noted current treatments have limited efficacy with high relapse rates, underscoring the need for further research into its mechanisms for better therapies.

This review discusses alopecia areata as a model for studying tissue-directed autoimmune diseases and reports no new clinical findings.

This review discusses the pathogenesis, clinical presentation, diagnosis, and treatment of cutaneous lupus erythematosus, reporting no new clinical findings.

This review outlines the advancements in organ and tissue transplantation since the discovery of the human MHC and reports no new clinical results.

This review discusses the role of the JAK-STAT pathway in autoimmune skin diseases and suggests potential therapeutic benefits of JAK inhibitors, but reports no new experimental results.

This paper reviews the use of interferons, particularly alfa interferon, in treating cutaneous T-cell lymphoma, noting its substantial efficacy both alone and in combination therapies with predictable, generally well-tolerated side effects.

This review noted that alopecia areata is an autoimmune disease impacting hair follicles and offered insights into its complex pathogenesis involving immune responses, while highlighting ongoing research into new treatments such as Janus kinase inhibitors and other immunomodulatory drugs.
