Studysummary The researchers observed that normal murine hair follicles are direct targets for melatonin, with receptor expression varying throughout the hair cycle, suggesting melatonin's role in hair cycle control. Our plain-language summary of this paper — not a Tressless recommendation.
The document discussed the expression and functional relevance of melatonin receptors in hair follicle biology, highlighting their role in hair growth regulation and potential use in treating hair loss conditions like alopecia. It provided evidence that melatonin receptors MT1, MT2, and RORα were present in murine hair follicles, with their expression varying according to the hair cycle. The study also noted that increased intracellular cAMP levels suppressed TGF-B-induced expression of extracellular matrix components in human dermal fibroblasts, suggesting that melatonin and related pathways could influence hair cycle dynamics and act as antagonists of fibrosis.
