CNR2 (Cannabinoid Receptor 2): CNR2 is a G protein-coupled receptor that binds cannabinoids and is primarily expressed in the immune system. It plays a crucial role in regulating immune responses, inflammation, and pain. Activation of CNR2 can produce anti-inflammatory and immunosuppressive effects, making it a significant target for treating inflammatory diseases, pain, and conditions requiring immune modulation. Understanding CNR2’s function offers promising therapeutic potential for autoimmune disorders, chronic pain, and other related conditions.
