This study found that involucrin likely plays a key role in forming the cornified material of the medulla and inner root sheath of human hair, contributing to its mechanical strength.

This study demonstrated that a keratin gel promotes nerve regeneration across critical defects in rabbit models, showing improved nerve conduction and muscle action potential compared to control treatments.

This study found that murine vibrissa hair follicle stem cells can differentiate into corneal epithelial-like cells in vitro when cultured with limbus-specific microenvironmental factors.

This research found that the microtubule catastrophe factor KIF18B plays a crucial role in promoting spindle orientation in keratinocytes, linking this process to cell fate decisions during hair follicle morphogenesis.

Vertebrate skin evolved to be more specialized and complex, especially in land animals.

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 review summarizes recent advances in understanding intermediate filament structure and their implications for pathological mutations and human diseases, but it reports no new experimental results.

This study suggests that pilomatricoma can differentiate towards various hair follicle structures, including hair matrix, hair cortex, follicular infundibulum, outer root sheath, and hair bulge.

This report describes a case of trichostasis spinulosa, a condition with pruritic, black papules on the face caused by keratotic plugs with embedded vellus hairs.

Keratin gene clusters in humans and marsupials are similarly organized.

This study identified and sequenced several keratin cDNA clones showing distinct expression patterns in mouse epithelia, with in situ hybridization highlighting differences in keratin distribution between normal and hyperproliferative tissues.

This case report describes a successful eyebrow reconstruction using hair follicle micrografts in a patient with dormant keratosis pilaris atrophicans, demonstrating potential for this technique in similar conditions.

This case report describes successful treatment of anaplasmosis in a Kintamani mix dog with doxycycline, ivermectin, vetadryl, and Livron b-plex, leading to improved activity, hair growth, appetite, and tick eradication.

This study observed that calcifying epithelioma of Malherbe is composed of tumor cells that differentiate into both hair cortex and outer root sheath, supporting its hair follicle origin.

This review discusses changes in keratin structure or gene expression that result in various skin disorders and reports no new clinical findings.

This study found that Trichosanthes kirilowii extract significantly enhances keratinocyte proliferation and wound healing in vitro and in vivo, suggesting its potential as a wound-healing component.

Feathers become harder as they develop due to a change in keratin type.

This study found that trichocytic cytokeratins, typically found in hair, are also present in nails, filiform papillae of the tongue, and the epithelial reticulum of the thymus.

This study found that different types of seborrheic keratosis demonstrate diverse differentiation patterns, highlighting its undifferentiated and hyperproliferative state with varying keratinization directions.

Hair proteins change location and structure as hair cells mature.

This case report describes a 30-year-old woman with keratosis pilaris treated with emollients and keratolytics, resulting in slight improvement.

This case report describes a 5-year-old girl with an extensive Microsporum canis scalp infection, highlighting griseofulvin as the preferred treatment and noting corticosteroids' benefit in severe inflammatory cases.

This study suggests that the expression patterns of keratin and filaggrin indicate milia may originate from the outermost cells of the hair bulge in the outer root sheath.

This study suggests that the epidermis of monotremes and marsupials exhibits a more primitive pattern of protein distribution compared to eutherian mammals, with differences in loricrin distribution and keratinocyte maturation.

This study found that both epithelial and hair keratins are expressed in beard hair medulla cells, exhibiting unique patterns and interactions distinct from other hair follicle and epithelial cells.
