This study found that silencing clock genes BMAL1 or PER1 in human hair follicles increased melanin content and melanocyte activity, suggesting these genes influence pigmentation.

This article reviews central centrifugal cicatricial alopecia in African-descent females, discussing possible causes, associated styling habits, and potential treatments, but reports no new clinical findings; the authors call for further research.

This review discusses the JAK-STAT pathway and the use of FDA-approved JAK inhibitors for autoimmune and inflammatory diseases but reports no new research findings.

This study introduced a novel in vitro assay for tracking melanosome transfer between melanocytes and keratinocytes, facilitating the quantification of melanin transfer and supporting the role of filopodia as a conduit.

This study found that in thin cutaneous melanomas, tumor regression is associated with a higher risk of sentinel lymph node involvement.

Fibroblasts can be turned into melanocytes for potential skin treatments.

This review discusses the efficacy and safety of topical JAK inhibitors for inflammatory skin conditions, reporting modest benefits in psoriasis and atopic dermatitis but mixed results for vitiligo and inconclusive data for alopecia areata.
