Mouse hair cells respond to male hormones by growing less, and this can be stopped by certain blockers.

In this study, researchers found that alopecia areata is linked to immune cell activation against hair follicle autoantigens and is associated with heart changes and cardiac marker alterations in humans and mice.

The document suggests a bacteria plays a significant role in acne rosacea and that white hair can regain color after transplant, meriting more research on reversing grey hair.

This study demonstrated that AIRE-deficient rats exhibit key symptoms of APECED, making them a relevant model for exploring potential treatments.

This review explores the autoimmune hypothesis of alopecia areata and the possible genetic and melanogenesis-associated autoantigens, but reports no new clinical findings.

This review discusses the challenges in identifying specific hair follicle antigens involved in initiating alopecia areata and highlights the need for further research to understand its etiopathogenesis, reporting no new results.

This study found that hairless mice with homozygous mutations developed significantly more aggressive basal cell carcinomas and a heightened inflammatory response to UVB exposure compared to their haired littermates.

This study found that stem cell transplantation effectively reduced acute inflammation-induced testicular damage, suggesting potential for cell-based therapies in addressing male infertility.

The study emphasizes that telomere shortening is identified as the sole cause of aging among the twelve hallmarks and suggests that increasing telomere and rDNA array length in adult stem cells might effectively reverse aging and extend lifespan.

This research highlights that engineered mice lacking the vitamin D receptor show multiple health issues similar to human vitamin D deficiency, underscoring the widespread impacts of the vitamin D endocrine system.

This article reviews the clinical presentation and histopathologic features of alopecia areata and proposes a hypothesis for its development, but it reports no new clinical results.

This review discusses genetic and environmental factors contributing to autoimmunity in alopecia areata and reports no new clinical findings, emphasizing the need for further study on its aetiology and pathophysiology.

This study observed that alopecia areata can be induced and serially transferred in C3H/HeJ mice using skin grafts, providing a useful model for studying the disease in humans.

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 review discusses the dual role of tissue-resident memory T cells in providing immune protection against infections and cancer and contributing to autoimmune skin disease pathology, without presenting new experimental results.

This article discusses the etiology, clinical features, diagnosis, histopathology, and treatment of alopecia areata but reports no new clinical findings; it emphasizes the palliative nature of current treatments.

This study showed that in C3H/HeJ mice, focal follicular inflammation starts before overt hair loss, with inflammation severity possibly reaching a threshold causing hair follicle dystrophy prior to visible hair loss.

This review highlights similarities in the development of thymus and skin epidermis, reporting no new results; the authors emphasize shared molecular mechanisms despite different embryonic origins.

In this study, alopecia areata patients treated with diphencyprone showed a significant increase in CD8 lymphocytes around hair bulbs, which may be associated with hair regrowth.

In this study, melatonin administration enhanced various cellular and structural features of the scrotal skin in Soay rams, including increased thickness, cell count, and gland activity.

This study found that injecting interferon gamma into C3H/HeJ mice did not alter the frequency or onset of alopecia areata, suggesting the protein alone does not trigger the disease.

This review discusses the mechanisms underlying immune tolerance failure in alopecia areata and highlights potential therapeutic avenues for restoring hair growth and achieving sustained remission, but reports no new clinical results.

In this case report, a 20-year-old male with folliculitis decalvans experienced remission of scalp lesions after treatment with doxycycline and topical ozenoxacin.

This review reports that hair follicles are dynamic neuro-immuno-endocrine organs with intrinsic signaling pathways, which play a crucial role in hair disorders like alopecia. It highlights emerging regenerative approaches targeting these pathways for hair restoration.

This review explores the potential of mesenchymal stem cells in skin regeneration and rejuvenation, highlighting their ability to modulate immune response and enhance extracellular matrix strength but does not provide new clinical evidence.

This study found that inhibiting the Mitochondrial Pyruvate Carrier in human scalp hair follicles caused metabolic stress that halted cell proliferation and disrupted key signaling pathways, with these effects partially reversed by an integrated stress response inhibitor.

In this study, the activation of Notch1 signaling in keratinocytes was found to play a key role in recruiting immune cells and facilitating skin repair after injury.

Ets2 gene is crucial for placental development in mice.

This study observed that baricitinib treatment led to significant improvement in a patient's alopecia areata symptoms and suggests further clinical trials to explore its potential as a treatment.

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