CNR2 (Cannabinoid Receptor 2): CNR2 is a G protein-coupled receptor that binds cannabinoids and is mainly expressed in the immune system. It plays a key role in regulating immune responses, inflammation, and pain. Activation of CNR2 can produce anti-inflammatory and immunosuppressive effects, making it an important 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 diseases.
