WEBMay 1, 2023 · Modulation of histamine’s effect occurs through four types of receptors: H1, H2, H3, and H4. Histamine receptors are G-protein coupled receptors, which are 7-transmembrane chain proteins that mediate the effect of several molecules. H1 receptors are Gq coupled receptors.
Histamine receptor - Wikipedia
WEBHistamine receptors are proteins that bind with histamine, a neurotransmitter involved in various physiological processes. There are four main types: H1, H2, H3, and H4. H1 receptors are linked to allergic responses, H2 to gastric acid regulation, H3 to neurotransmitter release modulation, and H4 to immune system function.
