Chromaffine zellen. Enterochromaffin cell

, Bernhard, Basel Schedlowski, Prof. 368, 1—94 1971. Upon activation, EC cells release to act upon serotonin receptors on ENS neurons. : Evidence for adrenergic nerve terminals and synapses in sympathetic ganglia. The proenkephalin then moves into the Golgi region and is enclosed in chromaffin vesicles, where proteolytic enzymes process it to yield free enkephalins. In exocytosis they the move to the cell surface, fuse with the plasma membrane and discharge their contents.

They reside alongside the lining the lumen of the digestive tract and play a crucial role in gastrointestinal regulation, particularly intestinal motility and secretion.

Secretion ensues.

The reaction proceeds in two stages with an initial rate limiting step involving the conversion of L-tryptophan to 5-hydroxytryptophan 5-HTP.

Es wurde jedoch kein Einfluss auf die Gesamt-Exozytose oder die Anzahl der dead-end Vesikel festgestellt.

Abnormal concentrations of serotonin have been associated with IBS, predominantly increased concentrations intensifying gastrointestinal motility and mucosal secretions from the gut mucosa.
