270-300 / 1000+ resultsresearch Structural changes in trichocyte keratin intermediate filaments during keratinization
Keratin structure changes during keratinization, but the exact model remains uncertain.
research Ultrastructural characteristics of trichilemmal cysts: report of two cases
Trichilemmal cysts may form from hair follicle outer root sheath growth.
research 1412 “Telescope model” for coordinated organ morphogenesis and stem cell formation
Developing hair follicles form from ring-shaped patterns, with future stem cells originating from the outer ring, not the upper layers, as previously thought.
research Organization of microfibrils in keratin fibers studied by X-ray scattering
The study improved understanding of keratin fiber structure by showing consistent microfibril diameter but varying distances and electron density profiles.
research Azimuthal Scattering from Elliptical Hair Fibers
Light scatters differently from elliptical hair fibers than from circular ones, and a new model better predicts this behavior, especially for shiny highlights.
research In vivo formation steps of the hard α-keratin intermediate filament along a hair follicle: Evidence for structural polymorphism
Hair follicles form hard α-keratin filaments in four steps, showing structural differences.
research Sequence analyses of Type I and Type II chains in human hair and epithelial keratin intermediate filaments: Promiscuous obligate heterodimers, Type II template for molecule formation and a rationale for heterodimer formation
Type I and Type II keratin chains can form heterodimers despite sequence differences.
research Cryo-Electron Microscopy of Trichocyte (Hard α-Keratin) Intermediate Filaments Reveals a Low-Density Core
Trichocyte filaments have a low-density core and may include proteins for hair structure.
research Three-dimensional architecture of macrofibrils in the human scalp hair cortex
Human hair has a complex, variable structure with a consistent matrix and double-twist pattern.
research Characteristic microstructure of curved human hair
Curved human hair has different structures on its convex and concave sides.
research Isolation of intermediate filament assemblies from human hair follicles.
Researchers isolated and identified structural components of human hair follicles, providing a model for studying hair formation.
research Identification of the C-terminal tail domain of AHF/trichohyalin as the critical site for modulation of the keratin filamentous meshwork in the keratinocyte
The C-terminal tail of AHF/trichohyalin is essential for organizing keratin filaments in keratinocytes.
research The structure of human trichohyalin : potential multiple roles as a functional ef-hand-like calcium-binding protein, a cornified cell envelope precursor, and an intermediate filament-associated (cross-linking) protein
Trichohyalin is a versatile protein involved in hair and skin structure.
research How a Bird Gets Its Feathers: Insights from Chromatin Looping
Feather patterns are influenced by enhancers and chromatin looping, and the structure of protein complexes important for hair growth has been detailed.
research Insights on the mechanical behavior of keratin fibrils
Keratin's mechanical properties are influenced by hydrogen bonds and secondary structure, and can be improved with the SPD-2 peptide.
research Structure and Mechanical Properties of Human Trichocyte Keratin Intermediate Filament Protein
Disulfide bonds make keratin in hair stronger and tougher.
research The Arrector Pili Muscle and the Follicular Unit of the Scalp: A Microscopic Anatomy Study
The study found that hair follicles are above muscle connections in the scalp, which may help protect stem cell areas.
research The cycling hair follicle as an ideal systems biology research model
The hair follicle is a great model for research to improve hair growth treatments.
research Structural Stability of Wild Type and Mutated α-Keratin Fragments: Molecular Dynamics and Free Energy Calculations
The Glu413Lys mutation in keratin affects hair stability, while Glu413Asp does not.
research Modeling of ionizing radiation induced hair follicle regenerative dynamics
Hair follicles can regenerate after radiation damage but not during a specific growth phase.
