Endocannabinoid system receptor distribution in the body
The Endocannabinoid System (ECS) is an endogenous multifunctional pro-homeostatic signaling system being almost ubiquitously distributed within the body.
The system is generally recognized to consist of three main parts:
(1) receptors: Cannabinoid receptor 1 (CB1R) and 2 (CB2R)
(2) Endocannabinoids: the body’s own signaling molecules regulating the ECS through the cannabinoid receptors, including N-arachidonylethanolamine (aka Anandamide, The Bliss Molecule) and 2-arachidonoylglycerol (2-AG) and
(3) the enzymes: responsible for the metabolism and regulation of endocannabinoids available at a given time.
In general, CB1Rs are primarily expressed within brain regions and the nervous system, especially in the central nervous system, and to a lesser extent at other sites of the body.
CB2Rs are primarily expressed within cells related to the immune system and peripheral body tissues.
