Molecular characterization of a peripheral receptor for cannabinoids

Munro, Sean, Thomas, Kerrie L., Abu-Shaar, Muna·1993·Nature

Abstract

The major active ingredient of marijuana, delta 9-tetrahydrocannabinol (delta 9-THC), has been used as a psychoactive agent for thousands of years. Marijuana, and delta 9-THC, also exert a wide range of other effects including analgesia, anti-inflammation, immunosuppression, anticonvulsion, alleviation of intraocular pressure in glaucoma, and attenuation of vomiting. The clinical application of cannabinoids has, however, been limited by their psychoactive effects, and this has led to interest in the biochemical bases of their action. Progress stemmed initially from the synthesis of potent derivatives of delta 9-THC, and more recently from the cloning of a gene encoding a G-protein-coupled receptor for cannabinoids. This receptor is expressed in the brain but not in the periphery, except for a low level in testes. It has been proposed that the nonpsychoactive effects of cannabinoids are either mediated centrally or through direct interaction with other, non-receptor proteins. Here we report the cloning of a receptor for cannabinoids that is not expressed in the brain but rather in macrophages in the marginal zone of spleen.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
