This study provides evidence for K1 and K10 derivatives' presence in the inner root sheath and hair cuticle, suggesting that these hair follicle parts may follow familiar keratinization principles.

Oxidized trichocyte keratin has a helical dislocation in its structure.

A method was developed to grow hair follicles in a lab for research on hair growth and health.

This study observed that applying a pulling force to hair follicles led to significant compression of nuclei in certain cell layers and distinct collagen changes at different follicle depths.

In this review, researchers examined the molecular diversity and expression patterns of major skin appendage proteins, like keratins and EDC proteins, in tetrapods, highlighting recent findings in reptiles and birds and identifying knowledge gaps for future research.

This study found that scaffolds made from human hair proteins supported better cell growth and interactions than control surfaces, indicating potential use in tissue engineering.

This study used ultrahigh-resolution optical coherence tomography to observe hair shaft structures, finding melanin granules absent only in white hair, which may explain color differences between black and white hair.

This research describes a two-step culture system for pluripotent mouse ES cells that produces hair follicle-like structures, providing a valuable model to study stem cell differentiation in vitro.

In this study, the ablation of Tet2/Tet3 genes in mouse skin epithelial cells led to altered hair shape and length, highlighting their role in regulating hair follicle gene expression and chromatin structure.

This study found that lentiviral vector tropism in three-dimensional skin tissue is distinct from keratinocytes in culture and is influenced by complex extracellular interactions.

This research found that a monoclonal antibody (MAb 17) specifically reacts with certain subunits of trichocyte keratin in rats, and discovered that trichocyte keratin expression in hair and whiskers begins at different embryonic stages.

This study's molecular dynamics simulations suggest that electrostatic interactions mainly stabilize peptide binding to human hair keratin, with the protein's dielectric constant significantly affecting free energy calculations.

This review discusses the role of keratins in epithelial cell stress protection and cancer, highlighting their potential as multifunctional regulators and diagnostic markers, without presenting new research findings.

This study reports promising preliminary results for using monoclonal antibodies to identify cashmere fibers, highlighting observed immunological differences from wool keratins.

This study demonstrated that molecular dynamics simulations of keratin could effectively model the mechanical properties of hair, aligning well with experimental data, especially when conducted in vacuum conditions.

This study suggests that human keratin fiber matrix has a well-defined nano-scale grainy structure rather than being amorphous, with grain size influenced by chemical treatments, temperature, humidity, and follicle-level factors.

This study found that keratin film from human hair samples responded to damage from UV, bleaching, perming, and thermal treatments, making it a useful model for evaluating hair damage in product development.

This study explored a keratin, sodium alginate, and carboxymethyl chitosan hydrogel modified with tannic acid and found it to have promising wound-healing qualities, including similar elasticity to human skin, antimicrobial and antioxidant properties, and effective water retention. These attributes suggest potential applications in biomedical engineering.

In this study, researchers found that a polyphenolic extract from Annurca apples, high in procyanidin B2, increased hair growth, density, and keratin content in healthy subjects after 2 months of use, and stimulated keratin biosynthesis in vitro.

This study presents computational modeling and experimental analysis of the HGT protein KAP8.1, identifying key structural features that may influence hair's response to environmental conditions.

This study identified a missense mutation in the keratin 71 gene as the cause of autosomal dominant woolly hair/hypotrichosis in a Japanese family, marking the first human mutation in KRT71 linked to a hair disorder.
