Histamine Definition:
One important inflammatory signaling molecule is histamine, which is stored in densely packed vesicles of mast cells, found in connective tissue.

Histamine Notes:
Histamine is an organic nitrogenous compound involved in local immune responses, as well as regulating physiological function in the gut and acting as a neurotransmitter for spinal cord and brain. Histamine is involved in the inflammatory response and has a central role as a mediator of itching. Histamine increases the permeability of the capillaries to white blood cells and some proteins, to allow them to engage pathogens in the infected tissues. As part of an immune response to foreign pathogens, histamine is produced by basophils and by mast cells found in nearby connective tissues.
