12 Feb 2008
Abstract excerpt
Cutaneous pigmentation is the major photoprotective mechanism against the carcinogenic and aging effects of UV. Epidermal melanocytes synthesize the pigment melanin, in the form of eumelanin or pheomelanin. Synthesis of the photoprotective eumelanin by human melanocytes is regulated mainly by the melanocortins alpha-melanocortin (alpha-MSH) and adrenocorticotropic hormone (ACTH), which bind the melanocortin 1...
