This study suggests that both the central biosynthesis and metabolism of progesterone to 3α,5α‐THP in the ventral tegmental area are crucial for facilitating lordosis in female rats.

This study suggests that Merkel cell polyomavirus T antigen-positive cells resembling Merkel cell carcinoma may originate from epithelial cells in human hair follicles, potentially informing future transgenic mouse models for this cancer.

This study suggests that an immune response to trichohyalin and keratin 16 may contribute to the pathogenesis of alopecia areata.

This study observed hair-specific transcription of a reporter gene in transgenic mice, with increased expression after dexamethasone and ultraviolet B treatment.

This study found that lymphatic vessels promote hair follicle growth in mice and may represent new therapeutic targets for hair loss conditions.

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

The LTF gene may help predict and manage nonspecific orbital inflammation.

This review discusses the unique properties, design, and fabrication of peptide hydrogels for biomedical applications, focusing on advances in drug delivery, gene therapy, and regenerative medicine; it reports no new clinical results.

This study found that trichohyalin is expressed in various normal and pathological epithelia beyond hair follicle cells, where it is uniquely associated with filaggrin, suggesting a specific role in aggregating K6/K16-containing intermediate filaments.

This study found that Epstein-Barr virus infection upregulated a truncated variant of human basic hair keratin 1 (hHb1-ΔN) in gastric carcinoma cell lines, suggesting a possible link to carcinoma differentiation.

This study found that marine-derived collagen peptides slightly promoted hair matrix proliferation and prolonged hair growth phase in human hair follicles ex vivo, suggesting potential benefits for hair loss treatment.

This case study suggests that autoimmunity involving cytotoxic CD8+ T cells may link alopecia areata and human T-cell lymphotropic virus-1-associated myelopathy in adult T-cell leukemia/lymphoma patients.

Biomimetic peptides improved hair growth and increased growth factors in hair follicles for hair loss patients.

In this study, both VEPA and ML-Y1 treatment regimens for older patients with non-Hodgkin's lymphoma showed similar response and survival rates, but neither was sufficient, indicating the need for a more effective approach.

FOL-005 peptide may help treat excessive hair growth safely.

The authors concluded that newly synthesized N-acyl-L-tryptophanyl-isoleucine amides showed high anxiolytic activity in animal models, comparable to diazepam, through interaction with the TSPO receptor.

Human hair follicles have their own thyroid hormone system.

This study found that transgenic mice expressing cgVEGF164 had increased hair follicle diameter and density, potentially linked to higher phosphorylation levels of ERK1/2, AKT1, and LEF1 proteins.

This study found that thymic stromal lymphopoietin (TSLP) promotes hair growth after skin injury by enhancing the proliferation of specific stem cells in hair follicles.

This study detailed the structure and amino acid composition of sheep trichohyalin, noting its presence in various tissues and suggesting a possible functional role beyond structural support in hair follicles.

In this mouse study, researchers found that orally administered low-molecular-weight fish collagen peptides significantly improved hair regrowth by both enhancing growth-promoting pathways and reducing inhibitory mechanisms.

This study demonstrated that both HR isoforms are expressed in keratinocytes, but HRDelta1072-1126 lacks corepressor activity and may act as a coactivator by inhibiting HDAC recruitment to the VDR transcriptional complex.

This study identified a monoclonal antibody, HKN-2, that recognizes specific cells in human skin and may indicate a common antigenic determinant between hair and other skin epithelial tissues.

This study describes a patient with hereditary vitamin D resistant rickets (HVDRR) who, despite having a truncated vitamin D receptor, did not exhibit typical hair or skin abnormalities, suggesting possible compensation via interactions with other proteins.

TRIV-509 quickly improves skin barrier and cell health in atopic dermatitis.

This study identified a specific LIPH gene mutation (736T>A) as common in Japanese patients with autosomal recessive woolly hair/hypotrichosis, potentially indicating its role in the condition's manifestation within this population.

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 a novel nonsynonymous genetic variant in the hHb1 gene of a family with monilethrix, which differs from ten previously reported pathogenic mutations.

This study identified a novel G207E STING mutation causing a distinct phenotype involving alopecia, photosensitivity, and thyroid dysfunction, and suggests that common polymorphisms in TMEM173 and IFIH1 may influence disease presentation.
