This review discusses the properties and extraction methods of keratins from natural fibers and highlights their promising applications in fields such as biomedicine, bioengineering, and forensic science, but reports no new experimental results.

This study demonstrated that keratin derived from human hair can improve axon extension and alleviate motor deficits from sciatic nerve injuries, highlighting its potential as a promising biomaterial for peripheral nerve regeneration.

This review discusses the genetic factors involved in hair follicle morphogenesis and cycling and reports no new clinical results; it emphasizes the role of genes in hereditary hair diseases.

This case report identifies a new type of hair matrix tumor called "rippled pattern trichomatricoma," distinguished by its unique cell arrangement and differentiation features.

This case study describes a young girl with sparse, brittle scalp hair and multiple keratotic papules, but no systemic or familial abnormalities were found.

This study found that epithelial keratin K 6 is associated with hyperkeratotic and ulcerated changes in the gastric pars oesophagea of pigs, suggesting epithelial proliferation plays a role in ulcer development.

This case report documents a 10-year-old girl with keratosis follicularis spinulosa decalvans, highlighting its rarity, particularly in females, and noting limited treatment success.

This study found that keratin biomaterials derived from human hair promoted significant motor function recovery and neuromuscular regeneration in animal models of peripheral nerve injuries.

This case report highlights the rare co-occurrence of Pili Annulati and Trichorrhexis Nodosa in a Syrian woman, underlining the need for further research into their relationship and treatment.

This study suggests that congenital atrichia with papular lesions may be more common than previously thought and proposes diagnostic criteria including the observation of hypopigmented whitish streaks on the scalp.

This study found that while the KRTAP gene family is unique to mammals, humans have a similar number of these hair gene types as other primates despite having less body hair.

This study found that hair follicle-specific keratins can form different structural assemblies depending on ionic conditions, with hair cortex keratins requiring physiological salt conditions to form intermediate filaments.

This case report indicates that trichoscopy may significantly improve the diagnosis of Netherton syndrome by noninvasively identifying typical hair abnormalities without the need to pull hair.

This case report describes a 5-year-old girl with atrichia with papular lesions, whose diagnosis was confirmed through genetic testing identifying mutations in the hairless gene.

This study identified a new 65 kD and 48 kD keratin pair expressed in specific mouse epithelial sites, suggesting a unique evolutionary branch of hair-related keratins.

A mutation in the KRT74 gene causes woolly hair by affecting hair texture.

A mutation in the KRT74 gene causes tightly curled hair.

This article reviews multiple noncutaneous manifestations of pityriasis rubra pilaris, such as subungual hyperkeratosis and hair loss, but reports no new clinical results.

This review discusses recent advancements in understanding neuroendocrine regulation of keratin biology and highlights the potential of neurohormones to treat skin disorders, but it reports no new clinical results.

This study identified WNT10A as crucial for adult epithelial cell proliferation and differentiation, suggesting β-catenin pathway activation may help address regenerative defects in WNT10A mutation patients.

This review discusses the history, structure, and biological significance of keratins, including the crystal structure of a keratin helical segment, without reporting new experimental results.

This study found that sphynx cats exhibit hair follicle dysplasia with abnormal hair shaft production, but without a reduction in the number of follicles, similar to murine KRT 71 mutants.

This review discusses the pathogenesis and challenges in treating primary cicatricial alopecia, highlighting the need to understand immune protection collapse in hair follicle stem cells; it reports no new clinical results.

In this study, researchers presented cases of cellular neurothekeoma in three male family members with early-onset in infancy, suggesting a potential genetic component and inheritance pattern, which deviates from the typical presentation seen mostly in women between 20–30 years.

This study suggests that the mechanical robustness of hair may be enhanced by the binding interactions of keratin-associated proteins, particularly KAP8.1, with intermediate filament proteins.

This paper reviews several dermatological studies, including findings on hair growth, skin damage, bullous pemphigoid, and psoriasis treatments, and reports no new clinical results.

This paper discusses the multipotency of cyst cells and proposes that understanding molecular circuits in cyst formation could enable engineering of desired stem cell culture phenotypes, but reports no new experimental outcomes.

This study observed that the catagen phase in hairless mice displayed a slower shortening of the mutant epithelial column, resulting in longer total follicle length and abnormalities in the connective tissue sheath and glassy membrane.
