Endocannabinoids Modulate Human Epidermal Keratinocyte Proliferation and Survival via the Sequential Engagement of Cannabinoid Receptor-1 and Transient Receptor Potential Vanilloid-1

We have recently shown that lipid mediators of the emerging endocannabinoid system (ECS) are key players of growth control of the human pilosebaceous unit. In this study, we asked whether the prototypic endocannabinoid anandamide (N-arachidonoylethanolamine, AEA) has a role in growth and survival of epidermal keratinocytes (KCs).

Cannabinoids inhibit human keratinocyte proliferation through a non-CB1/CB2 mechanism and have a potential therapeutic value in the treatment of psoriasis

Cannabinoids from cannabis (Cannabis sativa) are anti-inflammatory and have inhibitory effects on the proliferation of a number of tumorigenic cell lines, some of which are mediated via cannabinoid receptors. Cannabinoid (CB) receptors are present in human skin and anandamide, an endogenous CB receptor ligand, inhibits epidermal keratinocyte differentiation. Psoriasis is an inflammatory disease also characterised in part by epidermal keratinocyte hyper-proliferation.

The endocannabinoid system of the skin in health and disease: novel perspectives and therapeutic opportunities

The newly discovered endocannabinoid system (ECS; comprising the endogenous lipid mediators endocanna- binoids present in virtually all tissues, their G-protein- coupled cannabinoid receptors, biosynthetic pathways and metabolizing enzymes) has been implicated in multiple regulatory functions both in health and disease.

Perceptions and recommendation behaviors of dermatologists for medical cannabis: A pilot survey

Authors: Samuel Yeroushalmi, Kamaria Nelsona, Andrew Sparks, Adam Friedman Published in Complementary Therapies in Medicine September 2020 Abstract Objectives Evidence suggests that cannabinoids may provide therapeutic benefit to patients with dermatologic conditions. The recommendation behaviors of dermatologists with regards to recommending medical cannabis are unknown. We administered a pilot survey to evaluate dermatologists’ recommendation behaviors…
