Catestatin is a 21-amino acid peptide that is cleaved from its precursorchromogranin A. As a potent nicotinic cholinergic antagonist, Catestatin inhibitscatecholamine release from chromaffin cells and noradrenergic neurons. It also caninduce mast cell migration, degranulation and stimulate histamine release. It hasbeen suggested that early deficiency of Catestatin might play a pathogenic role inthe subsequent development of the hypertension. Catestatin also acts on innate immunity, and shows antibacterial activity againstGram-positive and Gram-negative bacteria.
