90-120 / 1000+ resultsresearch Building Models for Keratin Disorders
Krt16-deficient mice help understand skin disorders like PC and FNEPPK.
research Microstructure of Defective Mink Guard Hair
Defective mink guard hairs have split tips and missing cuticle cells, causing a metallic sheen.
research Formation of surface membranes in developing mammalian hair fibres
Mature hair surfaces are formed by keratinized cells with developed layers, not just modified plasma membranes.
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 Fine structure and immunocytochemistry of monotreme hairs, with emphasis on the inner root sheath and trichohyalin‐based cornification during hair evolution
Monotreme hair structure and protein distribution are similar to other mammals, but their inner root sheath cornifies differently, suggesting a unique evolution from reptile skin.
research ‘Plica neuropathica’: Matting of Hair
A girl's severely tangled hair couldn't be fixed and had to be cut due to a rare condition called plica neuropathica.
research Skin and hair regeneration after calciphylaxis. Histologic changes during formation and shedding of the calciphylactic carapace of the rat
After calciphylaxis, rats showed incomplete skin and hair regeneration, resembling scar tissue with fewer hairs.
research The Rhino Mouse: Retinoid Effects on a Model of Keratin Accumulation
Retinoids can help reduce keratin buildup in skin conditions.
research Central trichoptilosis with onycholysis
Hair splitting and nail detachment are linked conditions.
research Plica neuropathica: Bird's nest under dermatoscope
Plica neuropathica is a tangled hair condition that may be caused by hair damage or psychiatric issues and is treated by cutting the hair and addressing mental health.
research Trachyonychia with juvenile pityriasis rubra pilaris
A young boy with a rare skin and nail condition improved significantly with simple topical treatments.
research Plica polonica: Trichoscopic findings with a brief literature review
Plica polonica is a rare condition where hair becomes irreversibly tangled, and the treatment is to cut the matted hair.

The harlequin ichthyosis mouse mutation causes thick skin and early death, resembling a human skin disorder.
research Functional redundancy of Frizzled 3 and Frizzled 6 in planar cell polarity control of mouse hair follicles
Frizzled 3 and Frizzled 6 together control the orientation of mouse hair follicles.
research A histochemical examination of the epidermis of the southern elephant seal (Mirounga leonina L.) during the telogen stage of hair growth
The southern elephant seal's skin layer helps waterproof the skin by being tightly connected to hair shafts.
research Rippled‐pattern trichomatricoma
A unique hair tumor with a rippled pattern was identified, showing incomplete differentiation and unusual cell arrangements.
research Pseudofolliculitis cutis: a vexing disorder of hair growth
Pseudofolliculitis cutis causes painful skin bumps and needs proper shaving and treatments to manage.
research Cyclic Alopecia and Abnormal Epidermal Cornification in Zdhhc13 -Deficient Mice Reveal the Importance of Palmitoylation in Hair and Skin Differentiation
The enzyme DHHC13 is essential for healthy hair and skin, and its deficiency leads to hair loss and skin problems.
research Cornification in reptilian epidermis occurs through the deposition of keratin‐associated beta‐proteins (beta‐keratins) onto a scaffold of intermediate filament keratins
Reptile skin hardens by layering beta-proteins on keratin.
