This study suggests that label-retaining cells in the hair follicle contribute to follicular renewal, indicating a specific role in the hair cycle by proliferating during the late telogen phase.

This case report describes a 12-year-old boy with severe skin scaling due to novel compound heterozygous null truncation mutations in the TGM1 gene, resulting in loss of transglutaminase 1 activity.

This study identified a new cytokeratin, mK6irs, specifically expressed in the inner root sheath of mouse hair follicles, distinguishing it as a member of the type II cytokeratin family.

This article reports a case of linear lichen planus developing along the lines of Blaschko during intramuscular triamcinolone acetonide therapy for alopecia areata multiplex.

In this study, researchers noted that while Poly-L-lactic acid dermal fillers boost collagen synthesis to add volume and reduce wrinkles, there is no established link between these fillers and hair loss according to existing literature.

This study introduces a novel image enhancement method that significantly improves the visual quality of low-light sports images by utilizing improved bilateral filtering and the CLAHE algorithm, achieving a 65.24% improvement in color and edge detail preservation compared to state-of-the-art methods on the LOL dataset.

This study analyzed the molecular evolution and functional divergence of the Dkk gene family, finding accelerated evolution in Aves and Reptilia and identifying functional differences that may impact hair follicle development via Wnt signaling inhibition.

Keratin 79 cells help form and regenerate hair canals.

This study found that Meth-A cells induced alopecia in mice, but this effect was blocked by a protein kinase inhibitor, suggesting immunological mechanisms involving lymphokine-activated killer cells.

This report describes a case of epidermolytic hyperkeratosis in a newborn and her mother, both possessing a specific KRT1 gene mutation known to cause this skin disorder.

In this pilot study, PDLLA scalp microinjections showed improvement in physician-rated Global Aesthetic Improvement Scale scores over 12-24 weeks for 90% of patients with non-scarring alopecia, with no serious adverse events reported, although findings remain preliminary due to methodological limitations.

This study found that VE-cadherin and Alk1, traditionally linked to vascular functions, also play crucial roles in maintaining nerve homeostasis in mice during hair growth cycles by modulating certain cell populations.

In this study, repeated pregnancies in a murine model of systemic lupus erythematosus altered skin inflammation and cytokine expression but worsened kidney function and survival compared to controls.

This study found that low molecular weight collagen peptide from fish may promote hair growth in both human cells and mice by activating the Wnt/β-catenin signaling pathway.

This study suggests that sirolimus and propranolol may reduce abnormal lymphatic endothelial cell proliferation in lymphatic malformations, potentially improving vessel function and patient outcomes.

This preliminary study found that Melandrium firmum extract may promote hair growth and inhibit 5α-reductase, suggesting potential as a candidate for treating androgenetic alopecia.

This study reports the first known case of linear lichen planopilaris following Blaschko's lines in a nonfacial region.

This study observed that mesenchymal stem cell-conditioned medium accelerated burn wound healing in rats by enhancing epidermal growth factor presence, improving wound closure, collagen density, and re-epithelialization compared to the control.

New mutations in hair keratin genes cause the rare hair disorder monilethrix.

This study found that the Plcd3(mNab) mutation in mice worsens the alopecia caused by Plcd1 loss, suggesting synergistic effects between Plcd1 and Plcd3 on hair follicle health.

This study found that in lichen planopilaris, the basement membrane zone of the hair follicles exhibited disrupted and discontinuous staining patterns, potentially contributing to scarring and irreversible hair loss.

This study found that MPZL3 plays a crucial role in regulating the hair cycle clock in mice, with its absence leading to accelerated hair follicle cycling and suggesting potential therapeutic pathways for alopecia treatment.

This article discusses the use of low-level laser therapy for hair regrowth in men and women but reports no new clinical results; it reviews types of lasers and evidence from animal and human studies.

In this study, PP-PTKL exhibited antioxidant, anti-inflammatory, and pro-melanogenic effects in laboratory settings, suggesting its potential role in preventing or treating hair greying. Further animal and human studies are needed to verify these findings.

This study suggests that BLMP-1 is important for timely molting and oscillatory gene expression in C. elegans, indicating a potentially conserved mechanism for rhythmic skin regeneration.

This study concluded that dilated cardiomyopathy in Ctsl-deficient mice is mainly due to the lack of cathepsin L in cardiomyocytes, with additional heart stress from the fur defect.

This study found that the mutation Glu402Lys in keratin hHb6 may be associated with monilethrix, and homozygous patients in a consanguineous family exhibited more severe symptoms.

This study suggests that Mrp3 may play a role in both wound healing and the hair follicle cycle as a growth factor and/or angiogenesis factor.
