Application

Histamine has been used:
  • to stimulate regulated cellular secretion
  • in reaction mixture to activate blood for assaying thrombin (factor iia) activity by fluorimetry
  • to fill the luminal side of the chamber to investigate its effects on the TJ-related barrier and the expression of TJ (tight junction) markers in the vocal fold epithelium

Biochem/physiol Actions

Endogenous H1 and H2 histamine receptor agonist; H1 activation mobilizes Ca2+; H2 activation stimulates adenylate cyclase activity in neurons; activates nitric oxide synthetase; potent vasodilator.
Endogenous H1 and H2 histamine receptor agonist; activates nitric oxide synthetase; potent vasodilator.
Histamine participates in innate and acquired immune response, mediating allergy and inflammation. It helps in intestinal muscle contraction. During anaphylactic shock histamine causes bronchial constriction. Histamine is also involved in gastric acid secretion, epithelial and endothelial barrier control.

General description

Histamine is a neurotransmitter produced by neurons of the posterior hypothalamus. In the brain, histamine is predominantly present in the gray matter.
