This review introduces an integrated view of hair follicle behavior, highlighting a Yin Yang model of regulation and suggesting glycans as key elements in hair follicle growth control, without reporting new clinical findings.

This review identifies shared interferon gamma-driven immune pathways in vitiligo and alopecia areata, revealing potential targets for new treatments, but reports no clinical results.

This study identified the Arabidopsis cation chloride cotransporter CCC1 as essential for regulating pH and function in the trans-Golgi network/early endosome, with its absence causing significant growth and stress response defects.

This article explores how extrafollicular environments and stem cell configurations influence hair and feather regeneration but provides no new experimental results.

This review summarizes the current understanding of microRNAs in skin biology, highlighting their roles in processes like wound-healing and aging, without presenting any new experimental results.

This study found that upper-bulge epidermal stem cells in mouse hair follicles are specialized for nerve interactions, crucial for forming tactile sensory units, and influence touch responses via EGFL6 and αv integrin pathways.

In this study, cosyntropin-induced cortisol spikes did not affect hair cortisol concentration in captive grizzly bears, contrasting with stress responses observed in free-ranging bears during capture.

This Mendelian randomization study reports that lifelong increased free testosterone in males was associated with improved bone mineral density and body composition but increased risks of prostate cancer, hypertension, and several other conditions.

This study found that a combination of four transcription factors can transform mouse fibroblasts into cells resembling inner ear hair cells, potentially aiding research into hearing loss treatments.

This study found that the protein Formin 2 helps regulate cell-to-cell transport in thale cress by stabilizing actin filaments at plasmodesmata, with its absence leading to increased permeability and vulnerability to viral infections.

This study uncovered how Staphylococcus hominis transports an odor precursor molecule, potentially leading to new ways to control body odor production in humans.

This study found that the Lim-homeodomain transcription factor Lhx2 regulates Sonic Hedgehog signaling during early retinal neurogenesis in mice by controlling the expression of pathway genes in retinal progenitor cells.

This study observed that nevus melanocytes do not exhibit signs of senescence, suggesting that their growth arrest is due to cell interactions and not directly caused by BRAF activation.

This study found that IL18 signaling plays a crucial role in the homing and retention of mature regulatory T cells in the mouse thymus, primarily by upregulating the chemokine receptor CCR6.

This study found that type XVII collagen (COL17) regulates interfollicular epidermis proliferation in both neonatal and aged mice through Wnt signaling, suggesting its potential as a target for anti-aging skin strategies.

This study found that loss of the DNA methyltransferase Dnmt3a, but not Dnmt3b, increased carcinogen-induced squamous tumors in murine epidermis, with combined deletion leading to more aggressive and metastatic carcinomas.

Defective protein folding due to a mutation is key in ANE syndrome.

This review suggests that understanding the biological and molecular reasons for more severe COVID-19 in men, particularly those at risk for prostate cancer, could improve management of these patients, but reports no new results.

This study found that Plakophilin 1 regulates innate immune responses in keratinocytes by controlling RNA helicase activity, balancing inflammation during epidermal immune challenges.

In this study, researchers identified a specific T cell receptor associated with carbamazepine-induced severe cutaneous adverse reactions, demonstrating its potential for therapeutic development in patients with the HLA-B*15:02 genotype.

This review discusses genome maintenance mechanisms critical for preventing age-related diseases by preserving stem and progenitor cell potential, but reports no new empirical findings.

Hair can regrow after certain stem cells are lost because other stem cells can take over their role.

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 review summarizes recent findings on the role of lactylation, a novel post-translational modification, in skin diseases, suggesting its potential as a therapeutic target by linking metabolism, epigenetic regulation, and inflammatory processes.

This review discusses how inflammation influences hair follicle stem cell activities like wound healing and follicle cycling and suggests a potential link between inflammation, stem cell activation, and programmed cell death.

This study found that dengue virus infection caused inflammation and cell death in human hair-follicle dermal papilla cells, which may contribute to increased hair shedding observed during the epidemic in Taiwan.

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 study found diverse responses to the androgen dihydrotestosterone in rodent tissues, with most androgen-regulated processes being specific to particular tissues.

This study found that in stretch-mediated tissue expansion, fibroblasts adopt an embryonic-like, low-collagen state that enhances epidermal stem cell renewal, supporting coordinated skin expansion crucial for reconstructive surgeries.

This study provides a framework for understanding different types of alopecias based on immune privilege collapse at specific follicular sites, revealing distinct patterns in immune effector programs and stromal influences depending on the alopecia type.
