Serotonin antibody

Background of Serotonin antibody

Serotonin (5-hydroxytryptamine, or 5-HT) is a monoamine neurotransmitter synthesised in serotonergic neurons in the central nervous system and enterochromaffin cells in the gastrointestinal tract. Serotonin plays an important part in the biochemistry of depression, migraine, bipolar disorder and anxiety. It is also believed to be influential on sexuality and appetite. 5-HT is generally thought not to be released from synaptic terminal buttons in the manner of classical neurotransmission but from serotonergic varacosities into the extra neuronal space. From here it is free to diffuse over a relatively large region of space (>20µm) and activate 5-HT receptors located on the dendrites, cell bodies and presynaptic terminals of adjacent neurons. Serotonergic action is terminated primarily via uptake of 5-HT from the synapse. This is through the specific monoamine transporter for 5-HT, 5-HT reuptake transporter, on the presynaptic neuron. The pharmacology of 5-HT is extremely complex, with its actions being mediated by a large and diverse range of 5-HT receptors. Ab16007 may be a useful tool for characterization of carcinoids. In a study of 48 cases of adenomas and carcinoid tumours of the middle ear, the antibody labelled tumour cells in 12 cases (25%). In 1 case of carcinoid tumour of the middle ear, the antibody labelled tumour cells. In a study of 43 cases of bronchial carcinoid tumours, the antibody labelled tumour cells in 13 cases (30%). Cells labelled by the antibody display a cytoplasmic staining pattern.
