Cannabinoid receptors are specialized proteins found in the body that interact with compounds called cannabinoids. These receptors are part of the endocannabinoid system, which helps regulate various physiological processes, including mood, pain, and appetite. The two main types of cannabinoid receptors are CB1 and CB2. CB1 receptors are primarily located in the brain and central nervous system, influencing memory, coordination, and perception of pain. In contrast, CB2 receptors are mainly found in the immune system and peripheral tissues, playing a role in inflammation and immune response. Together, these receptors help maintain balance in the body.
