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 lead to anti-inflammatory and immunosuppressive effects, making it an important target for treating inflammatory diseases, pain, and conditions requiring immune modulation. Understanding the function of CNR2 offers promising therapeutic potential for autoimmune disorders, chronic pain, and other related ailments.
