Histamine is an organic nitrogen compound involved in local immune responses as well as regulating physiological function in the gut and acting as a neurotransmitter . [ 2 ] Histamine triggers the inflammatory response .
As part of an immune response to foreign pathogens , histamine is produced by basophils and by mast cells found in nearby connective tissues. Histamine increases the permeability of the capillaries to white blood cells and some proteins, to allow them to engage pathogens in the infected tissues. [ 3 ] Properties [ edit ] Histamine forms color hygroscopic crystals that melt at 84°C, and are easily dissolved in water or ethanol , but not in ether . Genetic Scientists Eliminate Schizophrenia Symptoms in Mice. A multinational group of geneticists writing in the journal Neuron has reversed schizophrenia-like symptoms in adult mice by restoring normal expression to a gene called Neuregulin-1 (NRG1 for short).
Roles of Neuregulin 1 in neural development. NRG1 is released from neurons to promote the formation and maintenance of radial glial cells. Tangential migration of γ-aminobutyric acid-ergic interneurons requires NRG1 in the cortical region. Logic.
