This study found that prolactin is a key regulator of keratin expression in human hair follicles, enhancing specific keratin types and influencing epithelial stem cell-associated keratins.

This study found that brain-derived neurotrophic factor (BDNF) inhibited hair shaft elongation and induced premature catagen development in cultured human hair follicles, partially through transforming growth factor β2.

This study observes the expression of mRNA for androgen receptor, 5α‐reductase, and 17β‐hydroxysteroid dehydrogenase in human dermal papilla cells.

This study found that 3D microtissue models of dermal papilla cells can enhance the ability to induce hair-follicle neogenesis in vivo, offering potential for controlled cell production in follicle regeneration.

This review summarizes the recent advances in molecular mechanisms influencing tissue sensitivity to glucocorticoids, emphasizing novel mutations and new information on the glucocorticoid receptor's circadian rhythm and ligand-induced repression, but reports no new results.

Hedgehog signaling helps keep hair follicle stem cells the same in both young and old human skin.

This study found that Notch-related genes, including Notch1 and Notch2, and their ligands and regulators, have distinct patterns of expression during mouse hair vibrissa follicle development and the adult hair cycle.

This study found that light stimulation of intrinsically photosensitive retinal ganglion cells in the eyes can activate hair follicle stem cells through a neural circuit involving the sympathetic nervous system.

This study established a new in vitro culture system that supports the growth and dynamic self-organization of hair follicle stem cells and their progeny, promoting a stable population equilibrium.

Certain fungi and bacteria help orchid seeds germinate and plants grow better.

This study found that overexpression of Wnt1a in bone marrow mesenchymal stem cells enhanced mouse hair follicle regeneration and promoted hair cycling.

This study found distinct gene expression profiles in alopecia areata-affected skin, suggesting T-cell mediated immune responses and unique gene profiles between different stages of the disease.

This review highlights the potential of near-infrared light therapy to improve metabolic, antioxidant, and cognitive functions without adverse effects, and supports its use for visual and neurological conditions through molecular and cellular mechanisms, as reported in this source.

This review discusses the role of peroxisome proliferator-activated receptors and their agonists in dermatology but reports no new clinical results.

This study found that the creation of hair follicle lumens in mice is driven by the outward migration of keratin 79-positive cells, suggesting a novel mechanism for generating hollow cores in hair follicles.

This study demonstrates that c-MYC overexpression in sebaceous glands affects differentiation via a regulatory axis involving the androgen receptor and p53, influencing carcinoma formation outcomes.

This study found that RANK-RANKL signaling regulates hair renewal and epidermal homeostasis in mice, revealing its role in initiating hair growth cycles and maintaining skin cell activity.

The researchers reported that during early embryogenesis and larval development in Silurana tropicalis, inhibiting steroidogenic enzymes cyp19 and srd5beta affects genes related to thyroid and reproductive systems.

This study suggests that a position effect disrupting TRPS1 expression may be linked to hypertrichosis in both Ambras syndrome in humans and a similar phenotype in Koa mice.

This study found that inhibiting PKC-β activity with bisindolylmaleimide reduces pigmentation in the skin and hair of guinea pigs and mice by preventing tyrosinase activation.

This study observed that in aged mouse skin, there was an increase in IL-17-expressing T helper cells, γδ T cells, and innate lymphoid cells, and blocking IL-17 signaling reduced skin inflammation and delayed age-related changes, suggesting it as a potential target to mitigate skin aging.
