This review discusses the role of keratins in maintaining epidermal structure and function and reports no new results; the authors emphasize the lack of rational therapies for skin disorders linked to keratin mutations.

This study used bioinformatics to explore molecular differences in testicular and ovarian responses to SARS-CoV-2, identifying genes that could be associated with sex differences in infection outcomes.

This study observed that the NOTCH signaling pathway may contribute to the development of fibrosis in systemic sclerosis by affecting epithelial cell changes, and inhibiting this pathway could prevent fibrosis in experimental models.

This preliminary study observed that melanoblasts are preserved in the white hair follicles of segmental vitiligo lesions.

This study investigated single-cell changes in photoaged skin, revealing distinct cell clusters and increased activity in PD-L1 and PD-1 pathways in sun-exposed areas, enhancing understanding of UVA-induced skin damage and potential prevention targets for photoaging and UV-induced skin cancers.

This study suggests that keratinocytes derived from hair follicles of patients with atopic dermatitis provide a useful model for investigating AD-related inflammation, as they showed greater expression changes of AD markers when stimulated with type 2 cytokines compared to those from healthy donors.

This study found that hyperbaric oxygen treatment in rats led to structural changes in epidermis and dermis, including decreased E-cadherin expression and increased connective tissue.

This study found that skin-infiltrating neutrophils play a crucial role in triggering chronic itch in atopic dermatitis by promoting skin hyperinnervation and enhanced expression of itch signaling molecules in a mouse model.

In this study using mouse models, researchers found that elevated IL-17a in aged olfactory epithelium impairs olfactory function, while IL-17a inhibition promotes regeneration and mitigates age-related decline.

This study found that elevated STAT5 levels are linked to improved hair-inducing capabilities in human dermal papilla cells, and reducing STAT5 impairs hair follicle induction.

The document concludes that managing skin conditions during pregnancy is important and requires specialized care.

The researchers reported that DHT may reduce the inflammatory responses induced by C. acnes in androgen-sensitive human sebocyte cells, suggesting a potential link between androgens and infection in sebaceous disorders.

This paper discusses the role of steroid sulfatase in hormone-dependent tumors and highlights the development of potent inhibitors, noting the commencement of a phase I trial for one inhibitor in postmenopausal breast cancer patients.

This review explores recent findings on regulatory T cells, focusing on their unique functions in non-lymphoid tissues and new mechanisms of action, but presents no original clinical results.

In this study, researchers found that exposure to PM10 significantly increased inflammation and impaired collagen synthesis in human dermal fibroblasts, suggesting PM10 contributes to skin aging through these mechanisms.

This review discusses potential mechanisms contributing to higher COVID-19 mortality among men, particularly the roles of smoking, genetic factors, and reproductive hormones, without presenting new clinical findings.

This study found that testosterone and 5α-dihydrotestosterone induced apoptosis in dermal papilla cells from nonbalding scalp regions, suggesting a high androgen stimulus can trigger cell death related to androgenetic alopecia.

This study found that children with alopecia areata experienced more stressful life events and excreted higher levels of catecholamines compared to healthy siblings.

This study found that Schistosoma mansoni cercariae stimulate epidermal keratinocytes in mice, initiating pro-inflammatory responses and barrier repair mechanisms akin to those in wound healing.

In this study, topical tofacitinib significantly increased hair regrowth in mice compared to minoxidil or vehicle, potentially due to elevated VEGF levels and reduced inflammation.

In this study, researchers found that impaired cholesterol biosynthesis in hair follicles may trigger an inflammatory immune response linked to primary cicatricial alopecia, providing new insights into the disorder's pathogenesis.

This article reviews sebaceous immunobiology and highlights the complex role of sebaceous glands and sebocytes in skin barrier function and inflammation, particularly in acne pathogenesis, but reports no new results.

This study found that prostaglandin D2 promotes androgen receptor and AKT signaling in human dermal papilla cells through the DP2 receptor, potentially contributing to androgenetic alopecia.

This article compares the immunology of cancer and the placenta and suggests that immunotherapy for pregnant cancer patients could be feasible with careful exploration, though no new clinical results are reported.

This review discusses the importance of heme oxygenase in skin physiology and disease, but it reports no new clinical results; the authors highlight its potential as a treatment target for conditions like atopic dermatitis and psoriasis.

This study suggests that Eclipta prostrata may promote hair growth in mice and human dermal papilla cells through regulating FGF-7 and mTOR signaling.

This article reviews the role of keratins in epithelial function and structure, discussing their involvement in growth control, organelle functions, and pathomechanisms of disorders, but reports no new clinical results.

This study found that topical application of Astragalus membranaceus extract induced hair regrowth and reduced immune response markers in mice with natural hair loss.

This study reviewed the role of inflammasomes in autoimmune skin diseases, highlighting their contribution to the pathogenesis of conditions such as vitiligo, alopecia areata, and psoriasis, and suggesting that targeting inflammasome dysregulation may offer new therapeutic options.

This review discusses the impaired functionality of regulatory T cells in the pancreas during the development of Type 1 diabetes, highlighting their role in disease pathogenesis, potential of Treg-based therapies, and challenges in clinical applications.
