research KERATINS AND SKIN DISORDERS
Changes in keratin affect skin health and can lead to skin disorders like blistering diseases and psoriasis.
research Keratin disorders: from gene to therapy
New treatments targeting specific genes show promise for treating keratin disorders.
research Keratin Promotes Differentiation of Keratinocytes Seeded on Collagen/Keratin Hydrogels
Keratin helps skin cells mature when added to a collagen mix, which could be important for skin and hair health.
research Keratinocyte differentiation in psoriatic scalp: morphology and expression of epithelial keratins
Psoriasis causes changes in certain keratins and shrinks sebaceous glands in the scalp.
research In this Issue
New findings on hair keratin, wound healing, and skin blistering were presented.
research Effect of Disulfide Bonds in Human Hair Fibers on the Melting Behavior of Their Crystalline Structure
Changing disulfide bonds in human hair affects its melting behavior and thermal stability.
research Keratin expression in mammalian skin, hair and nail [Abstract]
research Human hair proteins as natural reactive oxygen species scavengers for in vitro applications
Human hair proteins, especially keratins, can protect cells from oxidative stress in lab settings.
research The structure of the “amorphous” matrix of keratins
Human hair keratin fibers have a detailed nano-scale structure that changes with different conditions.
research Regulation of hard α-keratin mechanics via control of intermediate filament hydration: matrix squeeze revisited
Hard α-keratins stay stiff in water because the surrounding matrix keeps them dehydrated and strong.
research Disturbed Keratinocyte Differentiation in Transgenic Mice and Organotypic Keratinocyte Cultures as a Result of Spermidine/Spermine N1-Acetyltransferase Overexpression
Overexpression of SSAT causes hair loss and skin issues, but reducing putrescine can help.
research Outer root sheath keratinization in anagen and catagen of the mammalian hair follicle. A seventh distinct type of keratinization in the hair follicle: trichilemmal keratinization.
Trichilemmal keratinization is a unique process in hair follicles where the outer root sheath turns into keratin without a specific layer.
research Structure–property relationships of meta-kerateine biomaterials derived from human hair
Protein composition greatly affects the function of keratin biomaterials.
research Can be Hair-Keratin a Potent Biomaterial?
research The Binding of Small Molecules and Polymers to Keratin and Their Effects on the Physicochemical and Surface Properties of Hair Fibers
Certain small molecules and polymers can change hair's physical properties and how it feels by affecting the bonds within the hair.
research Suprabasal change and subsequent formation of disulfide-stabilized homo- and hetero-dimers of keratins during esophageal epithelial differentiation
Keratins K4 and K13 form stable dimers in mature esophageal cells, aiding cell stability.
research Analysis of structural change in keratin fibers resulting from chemical treatments using Raman spectroscopy
Chemical hair straightening changes hair proteins and mostly fixes broken bonds.
research Identification of two novel clusters of ultrahigh-sulfur keratin-associated protein genes on human chromosome 11
Two new gene clusters important for hair formation were found on human chromosome 11.
research IMMUNOHISTOCHEMICAL EXPRESSION OF KERATIN PROTEINS IN KERATOACANTHOMAS OF THE SKIN
Keratoacanthomas and squamous cell carcinomas have similar keratin patterns, making them hard to tell apart.
research Epidermal and hair follicle transglutaminases and crosslinking in skin
research Molecular modeling and structural characterization of a high glycine–tyrosine hair keratin associated protein
