This study was aimed to investigate the effects of cannabidiol on melanogenesis and its mechanisms of action in human epidermal melanocytes. WebFollicular melanocytes show cyclical activation, and “melanogenesis” (to produce melanin) is coupled with anagen in so-called anagen-coupled melanogenesis [25]. During the telogen phase, no melanin pigment is actively synthesized, with undetectable levels of tyrosinase and 5,6-dihydroxyindole-2-carboxylic acid oxidase [tyrosinase-related protein 1 (TRP-1)].
WebMelanization is initiated by proteases that cleave the zymogen prophenoloxidase (proPO) into active PO, which in turn oxidizes tyrosine derivatives into quinones that polymerize to form melanin. In Drosophila, crystal cells play a role in activating the melanotic response.
