Keratin heterodimers are preferred for their specific and structural advantages.

This article reports electron microscope studies on the structure of hair and wool, but it does not present new clinical findings.

This study identified two key pentapeptide quasi-repeats in human keratin-associated proteins, which are similar to motifs found in sheep wool.

In this case study, a 51-year-old Japanese man was diagnosed with desmoplastic trichoepithelioma after histological examination of surgically excised facial plaques.

The cuneate nucleus has two main neuron types: relay neurons and interneurons.

This study found that ephrin-A3 accelerates hair follicle development and increases hair follicle density in neonatal mice, suggesting its involvement in hair growth regulation.

This study found that mild-to-moderate COVID-19 was not associated with worsening in patients with pre-existing alopecia areata.

In this study, a keratin hydrogel improved survival rates and functional recovery in rats with spinal cord injuries, suggesting potential for SCI treatment that merits further investigation.

This review discusses Charnoly bodies as biomarkers of cell injury and potential therapeutic targets in neurodegenerative, cardiovascular, and cancer treatments but reports no new clinical results.

This study demonstrated that Gelfoam® histoculture supports extensive growth of both hair shafts and sensory nerves from isolated mouse whisker follicles over prolonged periods.

This article explores the complexity and significance of the hair follicle, emphasizing new insights into its biological roles and the involvement of p53 in follicular regression.

This study examined the use of keratin gel as a filler in nerve guides for peripheral nerve regeneration in a rat sciatic nerve injury model.

This article discusses multiple aspects of complex regional pain syndrome, including its diagnosis, pathogenesis, and treatment, but reports no new scientific findings.

In this study, researchers identified the ventral matrix as the primary source of nail plate formation, while the dorsal portion is generated by the apical matrix.

This study suggests that the absence of alpha5(IV)/alpha6(IV) chains in certain subepidermal basement membrane spots may relate to interactions with melanocytes in human skin.

This study found that asynchronous differentiation in human anagen hair follicles involves specific localization of c-Myc and interrelated genes Max and Bin1 along the inner root sheath.

This study suggests that typical skin lesions in Carney complex may originate from the pro-melanogenic activity of a specific dermal fibroblast population influenced by PKA signaling.

This study discovered a new region in the hair cortex where intermediate filaments are both aligned with the hair's axis and orientationally ordered, influenced by the cuticle boundary.

This study identified that the Wave complex proteins ABI1 and Wave2 play a crucial role in regulating epidermal shape and growth during skin development, notably influencing SOX9 expression and Wnt signaling pathways.

This study identified a cluster of genes on chromosome 17 related to hair keratin-associated proteins, including 37 genes forming seven multigene families, localized in the hair shaft's upper cortex.

The connective tissue around hair follicles changes structure throughout the hair cycle.

This review discusses the complex role of the EDA pathway in vertebrate skeletal development, emphasizing its interaction with other morphogenic pathways to influence skeletal diversity, but reports no new experimental results.

This study confirms that the proposed universal model for hard α-keratin structure applies to all known forms across various mammalian species.

This study introduces the term "hair matrix cyst" for a cyst with both pilomatricoma and epidermal cyst characteristics, highlighting its potential for misdiagnosis among similar skin conditions.

This study suggests that residues Val-889 and Arg-752 in the androgen receptor's steroid binding domain are crucial for NH2-/carboxyl-terminal interaction, affecting receptor stability and function.

This study found that keratins have evolutionarily conserved and domain-selectively enriched amino acids, which likely reflect their unique structural roles, with distinct patterns observed among epidermal, hair, and simple-type epithelial keratins.

This study suggests that specific combinations of human type I and II hair keratins, particularly K35-K85 and K36-K81, have distinct in vitro assembly properties that are significant for macrofibril formation.

In this study, two novel clusters of keratin-associated protein genes on human chromosome 11 were analyzed, suggesting their products are crucial for hair formation due to preferential expression in hair roots.

Hard α-keratin in hair has a unique, nonordered structure, different from other fibers.
