The histamine H3 receptor (H3R) was discovered in 1983 and was one of the last receptors that were discovered using conventional pharmacological methods. Its structure was discovered later as a part of an effort to identify a commonly expressed G-protein-coupled receptor (GPCR) in the central nervous system (CNS). The pharmacology of H3R is very complicated which has made drug development difficult. Many different functional isoforms of the H3R exist which means it co… WebJan 3, 2024 · H3 is the auto-receptor and activating it lowers histamine, as well as dopamine, GABA, noradrenaline and acetylcholine ( R ). Dopamine is created from the amino acids phenylalanine and tyrosine. Phenylalanine → tyrosine → L-Dopa → dopamine. Dopamine binds to 5 known receptors, namely D1 to D5.
