This study identified a group of dermal fibroblasts near hair follicle stem cells in mice that facilitate hair regeneration by creating a biomechanically compliant extracellular matrix, enhancing stem cell activation and promoting a positive feedback loop for tissue regeneration.

This study found that the lack of expression and deletion of specific hair keratin genes on chromosome 7q36 in Hirosaki hairless rats suggests the crucial role of these genes in hair growth.

Human hair follicles have their own thyroid hormone system.

This study identified a novel mutation, R430Q in the KRT86 gene, in a Han family with monilethrix, which may contribute to the disease's pathogenic mechanism.

Hairless protein helps control hair growth by regulating vitamin D receptor activity.

This study found that in lamivudine-resistant hepatitis B patients, tenofovir significantly reduced HBV DNA levels faster and more consistently than adefovir, reaching undetectable levels in all treated patients by 44 weeks.

In this case report, a 36-year-old patient undergoing secukinumab treatment for psoriasis experienced both hepatitis B reactivation and hair discoloration, suggesting a potential link between these effects, though further studies are needed to understand this relationship.

This study found that HMGB1 enhanced hair growth by stimulating PGE2 production in human dermal papilla cells, suggesting a potential therapeutic target for alopecia treatment.

This case report describes the first known association of hypertrichosis lanuginosa acquisita with autoimmune hepatitis, expanding the list of conditions linked to this rare disorder.

Human hair keratin genes hHa2 and hHb1 are located on chromosomes 17 and 12.

This review summarizes recent research and patents on 17β-HSD3, 17β-HSD5, and 3α-HSD3 inhibitors, suggesting their potential in treating androgen-dependent diseases, but reports no new clinical results.

This study reports that gastrointestinal problems, such as intractable diarrhea and enterocolitis, can dominate the clinical course of patients with Hoyeraal-Hreidarsson syndrome and may occur before hematological and immunological symptoms.

This proof-of-concept study reported that a new, ultra-fast, one-step immunohistochemistry method improved the interpretation of Mohs surgery slides, particularly for poorly differentiated tumors.

This study suggests that abnormal hair cycles in Hr mutant mice may be caused by HR protein overexpression, which down-regulates miR-31 and increases Tgf-β2 expression.

This study investigated the histogenetic relationship between basal cell carcinoma and hair follicles, revealing specific staining patterns of a monoclonal antibody in different skin tissues.

This study identified and characterized a murine type II hair keratin, demonstrating its presence in specific cells of hair and tongue tissues.

This review provides an overview of the hairless gene in mice and humans, discussing its structure, expression, and implications for understanding skin physiology and human disorders related to gene disruption, but it reports no new empirical findings.

This study found two recurrent missense mutations in the hHb6 gene associated with monilethrix in families from Russia and Colombia, supporting their role in this hair disorder worldwide.

This study found that preconditioning adipose-derived stem cells with HB-EGF enhanced their ability to promote hair growth in vivo by increasing their motility, paracrine effects, and survival.

This study identified a novel human type I hair keratin, hHa3-II, as an isoform of a previously described hHa3 keratin, with distinct sequence differences indicating separate gene encoding.

This study suggests that BBS7 is crucial for maintaining Sonic hedgehog signaling activity, which is essential for periodontal ligament homeostasis under occlusal hypofunction conditions.

In this study, a novel homozygous mutation in the STAT5B gene was identified in a 17-year-old boy with growth hormone-refractory growth failure, severe eczema, and autoimmune disease, suggesting a similarity to known STAT5B deficiency phenotypes.

This study observed that human hair keratin showed distinct morphological features depending on the dissolution speed, which could have potential applications in clinical settings for developing self-tendons.

This study found that a hypomorphic mutation in the Hr gene contributes to the development of diet-induced pruritic atopic skin in mice, particularly when combined with dietary deficiencies of polyunsaturated fatty acids and starch.

This study reports that the near-naked hairless mutation in mice is not an allele of the Hairless gene but may involve a mutation in a linked gene or a regulatory mutation.

This study found that human placenta hydrolysate effectively inhibited atopic dermatitis development in stimulated human cells and a mouse model, suggesting its potential as a therapeutic agent for related skin diseases.

This study found that BBS7 expression is crucial for maintaining Sonic hedgehog signaling activity and periodontal ligament homeostasis, suggesting its downregulation in occlusal hypofunction affects cell migration and angiogenesis.

This study found that BBS7 downregulation in occlusal hypofunctional PDL affects Sonic hedgehog signaling activity, impacting PDL homeostasis.

This study found that the loss of a functional hr gene in mice leads to premature and abnormal hair follicle regression, disrupting normal hair cycling and architecture.

This study found that the Bioengineered Exosomal Hair Growth Factors Complex (BEHC™) enhanced human follicle dermal papilla cell proliferation and reduced inflammatory markers in vitro, while significantly decreasing hair shedding and increasing hair density among participants with androgenetic alopecia in an open-label clinical study.
