Control of histidine decarboxylase gene expression in enterochromaffin-like cells.
The ability of histamine to stimulate gastric acid secretion was recognized over 75 years ago by Popielski [1]. The central importance of this action in the physiological regulation of acid secretion was established with the development of histamine H2 receptor antagonists by Black and colleagues in the early 1970s [2]. There has, however, been intense debate about the precise mechanisms of act...
متن کاملHistamine and histidine decarboxylase are correlated with mucosal repair in rat small intestine after ischemia-reperfusion.
The aim of this experiment was to demonstrate whether histamine and histidine decarboxylase (HDC) contribute to mucosal repair in small intestine subjected to ischemia-reperfusion (I/R). The superior mesenteric artery was occluded for 15 min followed by reperfusion. In jejunal mucosa, histamine content and HDC activity increased after I/R. Histamine output in mesenteric lymph was also elevated ...
متن کاملSurfactant-induced chronic pruritus: Role of L-histidine decarboxylase expression and histamine production in epidermis.
Shampoo and cleansers containing anionic surfactants including sodium dodecyl sulphate (SDS) often cause pruritus in humans. Daily application of 1-10% SDS for 4 days induced hind-paw scratching (an itch-related behaviour) in a concentration-dependent manner, and 10% SDS also caused dermatitis, skin dryness, barrier disruption, and an increase in skin surface pH in mice. SDS-induced scratching ...
متن کاملHistidine decarboxylase expression and histamine metabolism in gastric oxyntic mucosa during hypergastrinemia and carcinoid tumor formation.
Histamine is an important stimulator of gastric acid secretion. In experimental animals, inhibition of acid secretion by long term histamine2 receptor blockade causes hypergastrinemia, proliferation of enterochromaffin-like (ECL) cells, and formation of histamine-producing gastric carcinoids. The aim of this study was to examine the role of gastrin in histamine synthesis and metabolism of the o...
متن کاملEnhanced histamine production through the induction of histidine decarboxylase expression by phorbol ester in Jurkat cells
Histamine (HA), a mediator of inflammation, type I allergic responses and neurotransmission, is synthesized from L-histidine, the reaction of which is catalyzed by histidine decarboxylase (HDC). HDC has been reported to be induced by various stimuli, not only in mast cells and basophils, but also in T lymphocytes and macrophages. Although its mRNA...
