μ Opioid Receptors

The μ opioid receptor, (also known as OP3, MOP, MOR), is a member of the opioid family of G-protein-coupled receptors that also includes κ, δ and NOP receptors. Three splice variants of the receptor (designated μ1, μ2 and μ3) have been characterized.

The μ opioid receptor, (also known as OP3, MOP, MOR), is a member of the opioid family of G-protein-coupled receptors that also includes κ, δ and NOP receptors. Three variants of the receptor (designated μ1, μ2 and μ3) have been characterized, arising from the alternative splicing of the this gene.

μ Opioid receptors are distributed throughout the neuraxis (neocortex, thalamus, nucleus accumbens, hippocampus, amygdala) and in the peripheral nervous system (myenteric neurons and vas deferens). μ opioid receptors have been implicated in respiration, cardiovascular functions, feeding, learning and memory, intestinal transit, locomotor activity, thermoregulation, hormone secretion and immune functions. The human gene encoding the μ opioid receptor has been localized to chromosome 6 (6q24-q25).

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.
