The International Union of Pharmacology (IUPHAR) has established a Nomenclature Committee comprised of sub-committees of experts to evaluate types and subtypes of receptors and ion channels in an effort to establish universally accepted nomenclature [Vanhoutte, P.M., Barnard, E.A., Cosmides, G.J., Humphrey, P.P., Spedding, M., Godfraind, T., 1994. International Union of Pharmacology Committee on Receptor Nomenclature and Drug Classification. Pharmacological Reviews 46, 111-116]. This overview cites the reports of the IUPHAR subcommittees and other prominent review articles in an effort to compile receptors for lipid mediators that bind to and evoke their pharmacological responses via seven-transmembrane spanning, G-protein-coupled receptors.
