The Histamine acts as a neurotransmitter, or autacoid, whose histaminergic neuronsthat remain active during night hours, depending on the type of receptor, may stimulate or inhibit the CNV or the peripheral nervous system in the stomach (Secretin cells), skin, lungs, or muscles.

1) complete deacylation of phospholipids, which means even though temporarily a disappearance of the glycerophospholipids, and then the remodeling of their fatty acids, 2) the fate of sn-2 fatty acids liberated is well known but that of sn-1 fatty acids is not clear, and 3) it does not produce lysophospholipids, which are thought to be cytotoxic in general, although lysophosphatidic acid is an autacoid (73) and lysoPAF is a precursor of PAF.
