This review discusses the potential role of oxidative stress in hair graying and age-related alopecia, emphasizing the need for new strategies to counteract these effects, but reports no new results.

This article explores the dynamic and energy-efficient nature of telogen hair follicles, challenging the notion of dormancy, and highlights their potential in advancing treatments for hair growth disorders.

The AUTS2 gene is linked to neurological disorders and may affect human brain development and cognition.

This study shows that macrophage-induced TNF signaling can activate hair follicle stem cells and promote new hair follicle formation after wounding by regulating AKT/β-catenin pathways.

Scientists turned rat thymus cells into stem cells that can help repair skin and hair.

This study found that PDGFA is critical for the proliferation and maintenance of adipocyte stem cells in skin but not other white adipose tissues, highlighting unique regulatory mechanisms in different tissue depots.

This review examines current knowledge on human epithelial hair follicle stem cells, their markers, and outlines challenges in translating findings from murine studies to human research, but does not report new experimental results.

This review discusses the possible impacts of prolactin on skin conditions like psoriasis, alopecia, and stress-related dermatoses, emphasizing the need for further research to explore its therapeutic potential.

This review discusses various stem cell compartments in adult murine and human epidermis, examining their expressed markers and characterization assays, and reports no new experimental results.

This study found that epidermal Wnt production is crucial for forming the skin's spinous layer through a BMP-FGF signaling cascade, although Wnt from basal cells is not needed for their differentiation.

This review discusses the roles of αβ and γδ T cells in skin health and disease and reports no new clinical results; the authors highlight potential therapeutic developments.

The TGF-β family helps control how cells change and move, affecting skin, hair, and organ development.

This review explores animal models of alopecia areata, particularly focusing on the insights they've provided into the disease's immune mechanisms and potential treatment approaches, without reporting new experimental data.

This study found that FLCN deficiency in mice muscles led to increased mitochondrial biogenesis and a metabolic shift towards oxidative phosphorylation, with a similar advantage observed in FLCN-null kidney cancer cells.

In this study, increased corticosterone from chronic stress prolonged hair follicle stem cell quiescence in mice, inhibiting regeneration, but restoring Gas6 expression overcame this inhibition.

This review examines the role of Hairless, a nuclear receptor corepressor, in regulating Wnt signaling during hair cycling and reports no new clinical results.

This study found that blue light at a wavelength of 453 nm promoted hair growth ex vivo, potentially through interacting with OPN3 receptors in human hair follicles.

This paper argues that the cycling hair follicle serves as a valuable model for systems biology research, highlighting its potential for translational medicine.

This paper discusses the hypothesis that anti-acne agents may work by reducing FGFR2 signaling, and emphasizes FGFR2's potential role in acne pathogenesis, but it reports no new experimental findings.

This study found that activating Nrf2 in human hair follicles significantly reduced oxidative stress, lipid peroxidation, and protected against hair growth inhibition, suggesting a protective role for Nrf2 against redox insult in this context.

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 observed that in hormone-starved prostate cancer cells, the androgen 5alpha-dihydrotestosterone rapidly induces matriptase activation and shedding, which involves androgen receptor signaling and requires both transcription and protein synthesis.

This study found that the antiandrogen drug enzalutamide reduced TMPRSS2 levels and significantly decreased SARS-CoV-2 entry and infection in lung cells, supporting further clinical trials for COVID-19 treatment.

This study found that self-noncoding dsRNA activates TLR3 to stimulate intrinsic retinoic acid synthesis, promoting new hair follicle formation in wounded mice and showing similar gene expression changes in humans treated with rejuvenation lasers.

This study suggests that women with polycystic ovary syndrome may have a distinct metabolomic profile, differing in levels of amino acids, organic acids, and lipids compared to controls.

This review explores the role of Eph receptors and ephrins in skin cell processes, discussing their potential for therapeutic targeting in dermatological disorders, but it presents no new research findings.

The researchers reported that in mice, prolactin signaling in the skin epithelium inhibits hair follicle stem cell activation, promoting quiescence during periods of high serum prolactin like pregnancy and lactation.

This study found that Ldh activity in hair follicle stem cell-mediated squamous cell carcinoma is not necessary for tumorigenesis, as its modulation did not affect the cancer's development or characteristics.

This study suggests that ROXYs and reactive oxygen species are likely involved in the signaling pathways plants use to respond to nitrate deprivation.

This study found that sweat gland stem cells primarily maintain sweat gland homeostasis but can trans-differentiate to aid in epidermal healing and regenerate diverse skin structures under certain conditions.
