Effect of the calcium ionophore A23187 and aspirin on histamine release in vitro from leukocytes of aspirin-intolerant donors. 1984

B S Bochner, and L L Thomas, and L Godnik, and M Samter

In vitro histamine release from leukocytes of 10 aspirin-intolerant donors in response to the calcium ionophore A23187 and aspirin was compared to that of controls. Incubation with A23187 induced a concentration-dependent histamine release from leukocytes of all donors. At 0.1 and 0.2 micrograms/ml A23187, release from leukocytes of aspirin-intolerant donors was significantly less (p less than 0.01) than that of controls. Preincubation with aspirin failed to alter spontaneous or A23187-stimulated histamine release. Leukocytes of aspirin-intolerant donors do not demonstrate an enhanced sensitivity to histamine release stimulated by aspirin or A23187.

D006636 Histamine Release The secretion of histamine from mast cell and basophil granules by exocytosis. This can be initiated by a number of factors, all of which involve binding of IgE, cross-linked by antigen, to the mast cell or basophil's Fc receptors. Once released, histamine binds to a number of different target cell receptors and exerts a wide variety of effects. Histamine Liberation,Histamine Liberations,Histamine Releases

D000001 Calcimycin An ionophorous, polyether antibiotic from Streptomyces chartreusensis. It binds and transports CALCIUM and other divalent cations across membranes and uncouples oxidative phosphorylation while inhibiting ATPase of rat liver mitochondria.
