This study identified molecular elements controlling the expression and stabilization of THH protein in hair follicle cells, revealing key mechanisms that support hair shaft development in mice.

This study developed a novel monoclonal antibody, TYHF-1, which specifically reacts with hair keratins but not with epidermal keratins or various other tissue cells.

This report describes a case of granulomatous reaction to injectable poly-L-lactic acid in the periorbital area and suggests surgical excision as an effective treatment for persistent nodules.

This study found that alkylation of kerateine cysteine residues created a cell-compatible method for controlling hydrogel erosion rates and therapeutic agent release in keratin-based systems.

In this study, a porous keratin hydrogel derived from wool hair demonstrated strong mechanical properties and supported the growth of various animal cells, indicating potential as a scaffold in tissue engineering.

This study suggests that keratoacanthomas may be distinguished from squamous cell carcinoma by identifying hair follicle structures, based on keratin expression and histological features observed in tumor samples.

The study examined cytokeratin expression in different bovine epithelial tissues, finding that hair follicles and nasolabial glands express both acidic and basic types, while other epithelia express only one type.

This study suggests that human hair follicles may operate their own Cori cycle, synthesizing glycogen from lactate under conditions of lactic acidosis.

This article reports on a typical case of lichen planopilaris with foreign-body granulomas around hair shaft material, suggesting these may be an additional criterion for diagnosing late-stage LPP/FFA.

This study found no evidence of increased keratinocyte proliferation in acne vulgaris, suggesting that other mechanisms may be responsible for hyperkeratinization in acne pathogenesis.

This study developed microneedles loaded with Platycladus orientalis leaf extract to treat androgenic alopecia, finding that they can effectively deliver active ingredients into the dermis, promote hair follicle growth by removing free radicals, and activate the Wnt/β-catenin pathway.

This study suggests that pilomatrixomas' maturation towards areas of shadow cells is linked to a gradual loss of differentiation-specific hair keratins, supporting a hair matrix origin for the tumor.

Junctional proteins stabilize the inner root sheath and connect the companion layer in human hair.

Keratins are crucial for cell structure, growth, and disease risk.

Trichohyalin in hair can trigger immune attacks in alopecia areata.

This paper reports on the structural characteristics of α-type filaments in the inner root sheath cells of guinea pig hair follicles without presenting new clinical findings.

This study found that in human hair bulbs, telomerase is present mainly in the nuclei of cells undergoing proliferation, particularly in the matrix epithelium during the anagen phase, and sparsely in the outer root sheath during late catagen and telogen phases.

This study successfully developed and characterized a monospecific monoclonal antibody, LHTric-1, that specifically localizes to the pre-cortical region of the hair follicle and can aid research on hair and nail formation.

In this study, the researchers found that optic atrophy 1 (OPA1) is involved in the transition between filamentous and rounded mitochondria in hair follicle dermal papilla cells, potentially influencing cellular energy dynamics.

This study found that human dermal papilla cells are surrounded by a basement membrane-like extracellular matrix, which maintains their aggregated structure without strong cell‒cell contacts.

This study concluded that the inner root sheath inhibits the expression of certain differentiation markers in hair bulbs, with calcium-induced changes paralleling those seen in hair follicle mid-segments.

This study identified distinctive trichoscopic features that may aid in diagnosing loose anagen hair syndrome, such as rectangular black granular structures, solitary yellow dots, and a predominance of follicular units with single hairs.

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 case report describes a black male newborn who developed bullae that healed with hypopigmentation, linked to collagenolysis and RER vacuoles potentially containing proteolytic enzymes.

This study found that human adult dermal fibroblasts can express markers typically associated with neural cells, suggesting potential pitfalls in relying on immunophenotyping alone for cell identity verification.

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.

Eye lens capsules are the best for growing human skin cells.

This study observed that keratose, derived from human hair, integrated well in mouse tissue and remodeled with collagen, suggesting potential as a non-toxic biomaterial for regenerative applications.

This case report details a 36-year-old man with atypical necrobiosis lipoidica on his face, characterized by annular lesions and prominent giant cells without clear granuloma formation.

This report documents the first diagnosed cases of canine eosinophilic granuloma in Korea, identified through histopathological examination of skin nodules in two dogs.
