TLDR Activating cannabinoid receptor 1 reduces certain keratin levels, potentially aiding psoriasis treatment.
The study explored the role of cannabinoid receptor 1 (CB1) in regulating keratin expression in human skin, particularly focusing on keratins K6 and K16, which are up-regulated in psoriasis. Researchers found that activating CB1 with the agonist ACEA reduced the expression of K6 and K16 in human skin and cultured keratinocytes, effects that were partially reversed by the CB1 antagonist AM251. This reduction in keratin expression was independent of CB1's anti-proliferative effects on keratinocytes. The findings suggested that CB1-mediated signaling could be a novel mechanism for controlling keratin expression, with potential implications for psoriasis treatment and wound healing.
