Cannabinoid receptor type 2

Cannabinoid receptor type 2 (CB2) is a protein found mainly in immune system cells that help regulate immune responses and inflammation. It is part of the body's endocannabinoid system, which responds to natural chemicals called endocannabinoids, as well as compounds from cannabis. When activated, CB2 receptors can help reduce inflammation and modulate immune activity, playing a role in conditions like chronic pain, autoimmune diseases, and inflammation-related disorders. Unlike CB1 receptors in the brain that affect mood and cognition, CB2 receptors primarily influence immune health without causing psychoactive effects.
