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 type XVII collagen is crucial for regulating epidermal cells' proliferation in mice and may be a promising target for anti-aging skin treatments.

This case report found that the most likely cause of the patient's seizures and brain tumor was prior radiation exposure, with seizures managed effectively using intravenous lorazepam and subsequent treatment for the brain mass.

This narrative review examines the interactions between skin stem cells and their niches, finding new insights from advancements in genetic and imaging tools but reporting no new experimental results.

The research found that hair follicle–derived cytokines, particularly IL-15 and IL-7, regulate skin-resident memory T cells and their role in both immune homeostasis and lymphoma in the skin.

This study found that Myc activation in mouse epidermis impairs keratinocyte adhesion and motility by downregulating extracellular matrix and cytoskeleton proteins, affecting hair lineage differentiation.

This study found that the transcription factor Gata6 regulates the sebaceous duct lineage identity and plays a crucial role in epidermal wound healing by enabling dedifferentiation and broader lineage capabilities in post-mitotic cells.

The Dfl mutation in mice causes poor sebaceous gland function and complete hair loss.

This review discusses the unique advantages and challenges of microneedle arrays for vaccine and immunotherapy delivery but reports no new clinical results.

This review discusses allergic reactions to pollen in dogs, cats, and horses and suggests that these animals' spontaneous allergies could serve as models for translational clinical studies applicable to human allergies.

This study found that loss of the ACER1 gene in mice led to increased ceramide levels and progressive hair loss, highlighting ACER1's role in maintaining hair follicle stem cell homeostasis.

This study found that coactivating LIN28B and follistatin enhances cochlear supporting cells' ability to regenerate hair cells in neonatal mice by reprogramming them into progenitor-like cells.

In this study, researchers found that Dicer, but not Tarbp2, plays a crucial role in regulating the growth phase of hair follicles in post-natal mice.

This study found that transgenic mice with keratinocyte-specific overexpression of CtBP1 exhibited abnormal hair follicle development, suggesting CtBP1 may play a pathogenic role in hair morphogenesis.

In this study, researchers observed that acute stress increased levels of the enzyme 5αR2 in the medial prefrontal cortex of male rats, affecting stress reactivity, but this effect was not seen in females.

In this study, researchers identified Tenascin-C as a marker for touch dome keratinocytes, which maintain themselves and can develop into Merkel cells following injury, showing they share molecular traits with various epidermal keratinocytes.

This review evaluates traditional uses, phytochemical profiles, and pharmacological activities of Mediterranean Erica species, revealing the wide range of bioactive compounds and highlighting their antioxidant, anti-inflammatory, and antimicrobial activities. Further studies are suggested to fully understand their medicinal potential.

This study found that genetic variation in the KRTAP21-2 gene among crossbred Merino lambs was associated with differences in wool traits, particularly mean staple length.

This study found that ablation of Tet2/Tet3 genes in skin epithelial cells altered hair shape and length, leading to hair loss, by affecting chromatin accessibility and gene expression related to hair follicle regulation.

This review evaluates the traditional uses, phytochemical profiles, and pharmacological potential of Mediterranean Erica species and reports no new clinical results, highlighting the need for further studies.

This genetic study identified four new keratin-associated protein genes in sheep, revealing significant sequence variation and suggesting complex evolutionary dynamics, with unique variants in some sheep breeds linking them to Romanov sheep ancestry.

This study found that dietary serine levels influence hair follicle stem cells' ability to balance hair regeneration and wound repair, offering insights for potential interventions to accelerate wound healing.

In this study, hemp seed-derived exosomes (E40) showed potential for counteracting DHT-induced inhibition of feather follicle development in chicken embryos by modulating critical signaling pathways, suggesting a therapeutic approach for alopecia.

In this study, grape seed oil was found to be the most effective herbal oil for improving gloss and reducing fractures in various hair types.
