CB1 Receptors
The CB1 receptor, also known as the central cannabinoid receptor, is a member of the cannabinoid receptor group of G-protein-coupled receptors that also includes CB2 and GPR55. CB1 receptors are found mainly in the terminals of central and peripheral neurons.

The CB1 receptor, also known as the central cannabinoid receptor, is a member of the cannabinoid receptor group of G-protein-coupled receptors that also includes CB2 and GPR55. CB1 receptors are found mainly in the terminals of central and peripheral neurons, where they usually mediate inhibition of neurotransmitter release. They can also be present on some non-neuronal cells, including immune cells.
CB1 receptor antagonists are drugs that bind to the CB1 receptor and prevent its activation by endogenous cannabinoid receptor agonists (known as endocannabinoids). Some CB1 cannabinoidergic compounds, such as SR 141716A (Rimonabant), can produce inverse cannabimimetic effects when administered alone, they are known as CB1 receptor inverse agonists. CB1 receptor competitive antagonists, that lack any detectable ability to induce signs of inverse agonism, have also been developed.
The endocannabinoid system (endocannabinoids and their associated receptor proteins) is highly relevant in the control of metabolism and energy balance. Hyperactivity of the endocannabinoid system is associated with obesity; several CB1 receptor antagonists and inverse agonists have been developed in an attempt to reduce endocannabinoid signaling. Animal studies have shown that both food intake and body weight can be significantly reduced by blocking the CB1 receptor.

Addiction Poster
The key feature of drug addiction is the inability to stop using a drug despite clear evidence of harm. This poster describes the brain circuits associated with addiction, and provides an overview of the main classes of addictive drugs and the neurotransmitter systems that they target.
