Created by histidine decarboxylase, FTP, name this vasoactive amine whose actions are inhibited by Benadryl and are responsible for allergic reactions.
The turberomammillary nucleus of the hypothalamus releases this compound as a neurotransmitter, and it acts upon the medial forebrain bundle to cause arousal and vigilance. One receptor for this compound is found on the parietal cells of the stomach, where it triggers the release of HCl, and it is also stored in the enterochromaffin-like cells there. It is destroyed by the action of diamine oxidase and its namesake N-methyltransferase. Most commonly, it is released when the Fc-epsilon-RI receptor binds to immunoglobulin E, causing degranulation of mast cells.
