A biogenic amine is a biogenic substance with one or more amine groups. They are basic nitrogenous compounds formed mainly by decarboxylation of amino acids or by amination and transamination of aldehydes and ketones. Biogenic amines are organic bases with low molecular weight and are synthesized by microbial, vegetable and animal metabolisms ...
Biogenic amine receptor are a variety of neurotransmitter receptors that are sensitive to biogenic amine neurotransmitters. They mostly belong to the G protein-coupled receptor (GPCR) family of transmembrane receptors , specifically within GPCR "Family A" ( Rhodopsin -like receptors). [ 1 ]
MATs are located just outside the synaptic cleft (peri-synaptically), transporting monoamine transmitter overflow from the synaptic cleft back to the cytoplasm of the pre-synaptic neuron. [1] MAT regulation generally occurs through protein phosphorylation and post-translational modification . [ 2 ]
A phylogenetic tree showing how a number of monoamine receptors are related to each other. Monoamine neurotransmitter systems occur in virtually all vertebrates, where the evolvability of these systems has served to promote the adaptability of vertebrate species to different environments.
In mammals, histamine is an important biogenic amine with regulatory roles in neurotransmission, gastric acid secretion and immune response. [1] [2] Histidine decarboxylase is the sole member of the histamine synthesis pathway, producing histamine in a one-step reaction. Histamine cannot be generated by any other known enzyme.
Histamine, a biogenic amine, involves many physiological functions, including the immune response, gastric acid secretion, and neuromodulation. However, its rapid metabolism makes it challenging to measure histamine levels directly in plasma.

The vesicular monoamine transporter (VMAT) is a transport protein integrated into the membranes of synaptic vesicles of presynaptic neurons.It transports monoamine neurotransmitters – such as dopamine, serotonin, norepinephrine, epinephrine, and histamine – into the vesicles, which release the neurotransmitters into synapses, as chemical messages to postsynaptic neurons.
