This study suggests that Keratin 6hf may be a potential marker of oral squamous cell carcinoma and could play a role in its progression, though further research is needed to understand its function.

This study found that conditional knockout of N-WASP in keratinocytes of mice led to skin barrier defects, increased immune cell infiltration, and hyperproliferation of keratinocytes, indicating its crucial role in skin homeostasis.

This study suggests that basal cell carcinoma and trichoblastoma may share differentiation toward the hair follicle, as indicated by strong positivity in CK 15, follistatin, and Bmi‐1 markers.

This study found that sulforaphane and its related compounds may promote hair follicle growth in mice, suggesting their potential as treatment agents for androgenic alopecia.

This study reports that androgenetic alopecia patients exhibit reduced CK15 and tropoelastin expression and increased cellular senescence markers, indicating tissue damage in affected hair follicles and surrounding structures.

This study discovered nine human type I hair keratin genes, including a transcribed pseudogene, in a 190 kbp genomic region, revealing three gene subclusters based on sequence homologies.

This study demonstrated immunological cross-reactivity between mycobacterial heat-shock protein 65 and human epidermal cytokeratin 1/2, suggesting that this cross-reactive epitope might play a role in skin diseases.

This study identified 12 new genes associated with the hair follicle and various stages of the hair cycle in mice, which could lead to novel targets for hair growth or depilation therapies.

This study found that activating CB1 receptor signaling in human hair follicles increased stem cell proliferation while reducing differentiated cell survival, suggesting CB1's role as a survival stimulus for epithelial stem cells.

In this study, rabies virus antigens were detected in the outer root sheath of the follicle-sinus complex in the muzzle skin of rabid dogs, suggesting its usefulness as an alternative diagnostic specimen.

This study found that the expression of CK 15 and CK 19 in vitiligo patients undergoing phototherapy was correlated with improved repigmentation, suggesting their potential as markers for stem cell stimulation.

This proof-of-concept study reported that a new, ultra-fast, one-step immunohistochemistry method improved the interpretation of Mohs surgery slides, particularly for poorly differentiated tumors.

Keratin 17 is important for hair and nail structure and affects pachyonychia congenita symptoms.

This study found that a newly identified gene, mK17n, may explain the lack of nail issues in mK17 null mice by compensating for mK17's function in the nail bed.

This study found that the CD44(+) ALDH(+) population of neonatal human keratinocytes exhibited enhanced stem cell properties, including significantly increased long-term epidermal regeneration and multipotency, compared to unfractionated cells.

This study found that C8/144B antibody exclusively binds to the hair follicle bulge and not the epidermal stratum basale, with cytokeratin 19 serving as a key marker of certain basal keratinocytes that decrease with age.

This study identified thyrotropin-releasing hormone (TRH) as a stimulant of wound healing in both frog and human skin models, suggesting it as a potential neuroendocrine wound repair promoter.

This study revealed that during fetal development, MITF and Mart-1 expressing melanocytes progress from the dermis to the epidermis and hair follicles, with MITF possibly marking follicular stem cells.

This study suggests that androgens enhance growth factor production in dermal fibroblasts, which in turn may alter keratinocyte differentiation and contribute to acne lesion formation.

This study found that mice lacking the type 3 IP(3) receptor in their hair follicles experienced repetitive hair loss and regrowth, indicating disrupted hair-cycle regulation potentially linked to specific signaling pathways.

Cytokeratin-15 loss is not specific to any single type of scarring alopecia.

In this study, transfection experiments showed that mutations in the K85 gene affect filament formation with K35, which may impact hair formation related to ectodermal dysplasia.

This study observed that cytokeratins are expressed at specific stages during human fetal hair follicle development, with early markers indicating cellular maturation and later markers appearing in more developed follicles.

This review discusses unspecific factors involved in the pathogenesis of skin diseases and potential ways cytokeratin changes might alleviate these conditions, but reports no new clinical results.

This study found that VEGFR-2 activation may play a role in hair follicle differentiation, proliferation, and apoptosis by co-expressing with several key proteins in normal human scalp skin.

The study found that CK15 expression, representing hair follicle stem cell activity, was reduced or absent in scarred primary cicatricial alopecia lesions, suggesting stem cell damage may contribute to the scarring process.

This study found that sulfated CCK octapeptide reduces psoriasis-like skin inflammation in mice, suggesting a new pathophysiological role for CCK in regulating epidermal inflammation.

This study highlights the evolving understanding of acne's pathophysiology and suggests that targeting pro-inflammatory cytokines such as IL-1β, IL-17, IL-23, and TNFα with biological antibodies may offer new treatment strategies for severe acne and its scars.

This review discusses recent advancements in understanding neuroendocrine regulation of keratin biology and highlights the potential of neurohormones to treat skin disorders, but it reports no new clinical results.

This study observed that gerbils exhibit a different wound healing mechanism compared to mice, with lower TGF-B1 expression and distinct tissue responses, yet achieve similar healing outcomes.
