This study observed that in wild snowshoe hares, gene expression patterns during seasonal coat color change show a consistent lag between gene expression and visible coat color changes.

This review examines the challenges of hair follicle regeneration and outlines strategies for bioengineering human hair follicle models, without presenting new experimental results.

This study found that glucose starvation and hypoxia are physiological triggers of ER stress in in vitro differentiated adipocytes, rather than high concentrations of saturated fatty acids, cholesterol, or proinflammatory cytokines.

This study found that their novel 3D-imaging method, ASAXA-μCT, identified shrinkage of sweat glands as a key factor in skin aging, which leads to dermal defects, decreased elasticity, and increased wrinkling and sagging.

In this study, the novel ASAXA-μCT imaging method identified that the shrinkage of sweat glands with aging causes dermal defects, reducing skin elasticity and contributing to wrinkling and sagging.

This study found that although mature neutrophils and NETs are stimulated by a pro-regenerative cue, their presence actually hinders wound-induced hair follicle regeneration.

In this study, researchers identified a highly reactive, isozyme-specific sequence for TGase 3, contributing to understanding its distinct functional role and activity distribution in the mouse epidermis.

FGF18 helps keep hair in its resting phase, affecting hair growth cycles.

This study reported that the NUDT15 R139C genetic variant was significantly associated with thiopurine-induced leukocytopenia in Japanese inflammatory bowel disease patients, independent of 6-thioguanine nucleotide levels.

This study found that solid basal cell epitheliomas and the outer root sheath of human hair follicles display nearly identical cytokeratin profiles, suggesting a potential origin connection.

This study found that minoxidil increased 17ß-hydroxysteroid dehydrogenase activity by nearly 40% in dermal papilla cells from balding scalps but not in nonbalding scalp cells or dermal fibroblasts.

This retrospective study found that serum hormone levels and MRI detection of ovarian nodules contributed to distinguishing virilizing ovarian tumors from ovarian stromal hyperthecosis in postmenopausal women, though histopathology remains crucial for diagnosis.

This study found that protease nexin-1 mRNA is expressed in human dermal papilla cells and is downregulated by dihydrotestosterone in balding scalp, suggesting a role in male-pattern baldness progression.

This study found that treating neonatal mice with the neurotoxin 6-OHDA resulted in temporary hair loss and thinner skin compared to control mice, linking sympathetic neurons to hair growth and skin thickness.

This study presents a bioprinter-based method for creating scalable, automated hair-inductive tissue grafts that showed improved hair shaft sprouting in mice by using suture guides to control orientation.

This case study reports that the topical application of mometasone furoate ointment successfully reduced eruptions and promoted hair regrowth in a patient with amicrobial pustulosis.

This study found that activating the PI3K/Akt signaling pathway in dermal papilla cells enhances their hair-inducing capabilities, suggesting potential strategies for hair regenerative medicine.

In this study, long-term normalization of testosterone levels in postmenopausal women with hyperandrogenism did not improve body mass index, glucose, or lipid metabolism.

In this study, researchers found that thrombin may influence cyclic hair growth through its receptor PAR-1, although it does not seem to stimulate dermal papilla cell proliferation physiologically.

This study found that the keratin expression in basal cell carcinoma resembles that of the pilosebaceous apparatus, with uniform presence of certain keratins in all cases.

This report details a rare case of favus in Japan, identifying Trichophyton schoenleinii in a 63-year-old woman through DNA sequencing, who was successfully treated with oral terbinafine and topical luliconazole.

This study examined the expression patterns of various cytokeratins in the outer root sheath of human anagen hair follicles, noting distinct differentiation patterns and localization of keratin markers.

This study presents a novel, scalable method for preparing highly hair-inductive tissue grafts using a bioprinter, which enhances hair follicle regeneration in mice, although most hair shafts remained beneath the skin.

This study observed that mature neutrophils and their extracellular traps inhibit wound-induced hair follicle neogenesis in mice, despite being stimulated by pro-regenerative cues.

This study found that alopecia areata patients who responded poorly to topical immunotherapy had impaired peripheral blood mononuclear cell responses to T-cell stimulants.

This study found that peptidylarginine deiminase type III and trichohyalin are coincidentally expressed in the infant rat hair follicle, but trichohyalin deimination occurs after their expression during development.

This research overview provides insights into current in vitro models for drug testing in hair loss treatments, highlighting the limitations of traditional models and the progress in developing three-dimensional culture platforms for more effective screening of potential therapies.

FGF18 controls hair growth rest phase.

In this study, the ethanol extract of Tridax procumbens leaves exhibited antimicrobial activity against both Gram-positive and Gram-negative bacteria, with specific active compounds identified through GC-MS analysis that may contribute to its therapeutic potential.

In this study, researchers successfully generated hair follicle organoids using human induced pluripotent stem cells (hiPSCs) with collagen I as a microenvironment, demonstrating potential applications in hair regeneration, though fully human organoids require additional approaches.
