title: Histamine in brain development and tumors.
abstract: Histamine is found in developing mammalian brain in both neurons and mast cells. Under normal conditions, histamine H1 and H2 receptors are found in neural, glial and endothelial cells, and H3 receptors at least on neurons. Experimental brain tumors display both H1 and H2 receptors, and histamine increases permeability in the tumors and in the neighboring areas. Many studies have addressed histaminergic signalling mechanisms in cell lines originating from brain tumors. However, the role of histamine in normal development of brain structures, proliferation and differentiation of neurons and glial cells, and growth of malignant tumors in situ is still poorly understood.
