TRPV1 is part of the transient receptor potential family and is one of the non-GPCR cannabinoid receptors. TRPV1 is involved in thermoregulation and pain detection (nociception).

GPR18 is involved in apoptosis, microglial migration in the CNS and other immune responses.

CB2 is primarily expressed in the immune cells and tissues of the body. Like CB1, CB2 is a G protein-coupled receptor which inhibits adenylyl cyclase and consequently lowers cAMP upon activation. This, in turn, regulates many second messenger pathways.
