Preferred Label : receptors, sigma;
MeSH definition : A class of cell surface receptors recognized by its pharmacological profile. Sigma
receptors were originally considered to be opioid receptors because they bind certain
synthetic opioids. However they also interact with a variety of other psychoactive
drugs, and their endogenous ligand is not known (although they can react to certain
endogenous steroids). Sigma receptors are found in the immune, endocrine, and nervous
systems, and in some peripheral tissues.;
