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.

New findings on hair keratin, wound healing, and skin blistering were presented.

In this study, a rare case of a trichilemmal cyst in a 6-year-old's upper eyelid was observed; it was identified through histopathological examination after excision, highlighting the importance of considering trichilemmal cysts in atypical pediatric eyelid swellings.

This study found that murine vibrissa hair follicle stem cells can be differentiated into corneal epithelial-like cells in vitro using limbus-specific microenvironmental factors, suggesting a potential therapeutic source for ocular surface disorders.

In this study, hydrolyzed keratin supplementation using KeraGLO® significantly improved skin parameters such as wrinkle depth, smoothness, moisture, and firmness, as well as hair health, in healthy adult females over a 90-day period at both 500mg and 1000mg doses.

This study observed an association between intense itching in anterior chest keloids and an increased density of nerve fibers in the epidermis, alongside elevated expression of the pruritus mediator substance P, though no difference was found in Langerhans cells related to pruritus, location, or region.

This review discusses the biological roles and diagnostic significance of keratins in mammalian colon epithelial cells and reports no new clinical results.

This study found that in mouse pancreatic β-cells, the disruption of keratin filaments due to a specific mutation in keratin 18 resulted in altered GLUT2 localization, with less GLUT2 present on the plasma membrane compared to cells with normal keratin.

This study found that keratin genes in the epidermis of aquatic mammals like cetaceans have evolved to replace stress-inducible keratins K1 and K10 with constitutively expressed K6 and K17, suggesting adaptations to their environment.

This study describes trichilemmal keratinization as a distinct process of hair follicle keratinization that occurs in specific areas of the outer root sheath, illustrated using electron microscopy on dog hair.

Calretinin identifies the companion cell layer in human hair follicles.

Cornification evolved from keratinization in vertebrates, with differences between mammals and sauropsids.

In this study, researchers found that the curliness of human hair is associated with an asymmetric structure at the cellular level, particularly in the differentiation of the precortex.

In this case report, a 27-year-old woman with a swelling on her neck was initially misdiagnosed with squamous cell carcinoma, but was later identified as having pilomatrix carcinoma with lymph node metastasis, highlighting the importance of accurate diagnosis for effective treatment and prognosis improvement.

This study suggests that human keratin fiber matrix has a well-defined nano-scale grainy structure rather than being amorphous, with grain size influenced by chemical treatments, temperature, humidity, and follicle-level factors.

In this retrospective chart review, researchers found that keratinocyte carcinomas on the scalp and forehead of non-alopecic women occurred more frequently in the part line of the scalp, with basal cell carcinoma being more common than squamous cell carcinoma.

This case report highlights the successful treatment of Kaposi varicelliform eruption in a pemphigus vulgaris patient using intravenous acyclovir, alongside antibiotics, resulting in healing of skin lesions with scarring.

This product description promotes Kerablak Calcium Pantothenate Tablets for improving hair strength and reducing hair fall, but it provides no new clinical study findings.

In this case study, the researchers reported that surgical debridement combined with targeted dermatological and antimicrobial therapy effectively managed chronic lower-limb wounds in a patient with keratitis-ichthyosis-deafness syndrome, underscoring the importance of a multidisciplinary approach in treating this rare condition.

This study reported that K14 expression patterns and keratin filament organization in human skin's hair follicles differ from those in the epidermis, indicating distinct differentiation programs.

This study identified 53 keratins in the yak genome, predicting diverse phosphorylation sites and subcellular localizations, and highlighted strong gene expression correlations during the yak hair follicle development cycle.

This case report describes an 18-year-old man with pili annulati, characterized by a "shagreened" appearance of the hair shaft with alternate bright and dark bands and wide holes throughout the cortex.

This case report suggests a successful outcome with intralesional cidofovir for SCC, although surgical excision remains the preferred treatment.

This report describes a case of secondary cutis verticis gyrata due to a cerebriform intradermal nevus, highlighting clinical management and screening guidelines.

This study on Indian dromedary camel breeds investigated the KRTAP7 protein, finding all four breeds shared an identical gene sequence, with 13 phosphorylation and glycosylation sites influencing hair characteristics, alongside predicted interactions with other biosynthesis-related proteins.
