In this study, a 5-year-old Angus bull experienced systemic granulomatous disease and vasculitis potentially associated with grazing on hairy vetch, but other bulls in the same pasture showed no symptoms, suggesting variability in disease manifestation from similar exposures.

The document explains various skin conditions and their treatments.

This study found that activation of Wnt/β-catenin signaling in mouse testes promotes spermatogonial differentiation and reduces the stem cell pool, with SHISA6 inhibiting this process and maintaining stem cell characteristics.

This article reviews the therapeutic use of interferons and other cytokines in various viral, tumorous, and inflammatory diseases, discussing their biological effects and potential future applications without presenting new experimental results.

Hidradenitis Suppurativa is a chronic skin condition best treated early with surgery for better outcomes and less recurrence.

This review summarizes how single-cell omics technologies have advanced understanding of cellular regulatory programs in sheep and goats, but highlights limitations in genomic annotation and integration with population genetics for molecular breeding.

This study identified CD28, GZMB, and CD1C as key immune regulators in alopecia areata, highlighting CD28 as a potential therapeutic target with a promising safety profile, using a proteome-anchored multi-omics approach to uncover actionable targets for this autoimmune hair-loss disorder.

This study identified Th22 cells as key effectors in hair regeneration driven by thymosin beta 15, suggesting they could be potential targets for hair regrowth therapies.

This study provides a detailed analysis of cell subpopulations in a mouse model of wound-induced hair follicle regeneration, revealing specific cellular dynamics and heterogeneity that may influence hair follicle neogenesis.

This study suggests that mNotch expression plays a significant role in hair follicle differentiation and cell fate selection within the follicle during development.

This study found that male pattern baldness in European males is strongly heritable and associated with genetic markers linked to earlier puberty, bone density, and pancreatic function.

This study suggests that while VDR is crucial for maintaining hair follicles in mice, their degeneration may be linked to impaired cell migration during hair growth phases rather than stem cell loss.

This study demonstrated that stress inhibited hair growth in mice, likely through substance P-dependent activation of immune cells, highlighting a brain-hair follicle connection.

This study found that local injections of interleukin-4 and neutralizing anti-interferon-γ antibody effectively treated alopecia in a mouse model, suggesting potential therapeutic pathways for human alopecia areata.

This case study describes a patient with rapidly progressing follicular mycosis fungoides, highlighting its unusual histology and challenges in diagnosing it against cutaneous B-cell lymphoma.

A kidney transplant patient on cyclosporin experienced unexpected severe hair loss, which improved with treatment adjustments.

This review discusses the distinctive non-infective skin presentations of HIV infection from a dermatological perspective and reports no new clinical findings.

This study suggests that STAT3 signaling in keratinocytes is crucial for maintaining skin homeostasis by regulating hair follicle-specific keratin genes, potentially impacting dermatitis development through microbe-triggered inflammatory responses.

This article reports on a partial regrowth of scalp hair in a patient treated with extracorporeal photochemotherapy and interferon α 2a, but provides no new clinical outcomes.

This article reviews various hair growth and hair loss treatments, noting limited new developments since FDA-approved drugs but highlights recent cosmetic surgery and potential cell-based therapies; it reports no original findings.

This review compiles existing data on frontal fibrosing alopecia and highlights the promise of 5-alpha reductase inhibitors as a treatment option, while noting the need for clarity on its cause and progression.

This case report details an occurrence of Vogt-Koyanagi-Harada disease during pegylated interferon-α2b and ribavirin therapy for chronic hepatitis C.

This study found that deleting Snai2 and Snai3 genes in mice disrupts immune cell development, resulting in severe autoimmunity and early death due to the loss of immune tolerance.

This study found that lineage-restricted loss of p63 in murine thymic epithelial cells resulted in severe thymic hypoplasia and absence of hair follicles, indicating p63's critical role in thymic and hair follicle development.

This synopsis reviews key dermatological advancements discussed at the British Association of Dermatologists meeting in 2011 and reports no new clinical results.

Aldesleukin can treat certain cancers and increase HIV patient CD4+ counts but often causes severe side effects.

This review discusses how tissue resident memory T cells contribute to autoimmune skin diseases like vitiligo and psoriasis, highlighting their role in continuous immune activation, and reports no new clinical results.

This article reviews the emerging non-inflammatory roles of regulatory T cells in the skin and reports no new clinical findings, suggesting broad biological influence beyond traditional immune functions.

This article reviews the epidemiology, clinical evaluation, and pathogenesis of alopecia areata and highlights recent advancements, but it does not report new clinical findings.
