Bradykinin is a potent vasoactive nonapeptide. It elicits a rise in cytosolic Ca(2+) (Ca(2+))(i) in endothelial cells, resulting in Ca(2+)-dependent synthesis and release of endothelial vasodilators. In the present study, we investigated the mechanism of bradykinin-induced Ca(2+) influx in primary cultured rat aortic endothelial cells and in a mouse heart(More)
A compound that can enhance the apparent synthesis of acetylcholine in cultured explants of the medial septal nucleus has been purified from rat brain and identified as phosphoethanolamine. Acetylcholine synthesis is stimulated two- to threefold in cultures grown for 5 days in the presence of phosphoethanolamine, ethanolamine, or cytidine(More)
Natural killer T cells with invariant αβ-T cell receptors (TCRs) (iNKT cells) constitute a lipid-responsive arm of the innate immune system that has been implicated in the regulation or promotion of various immune, infectious and neoplastic processes. Contact sensitivity (CS), also known as contact hypersensitivity or allergic contact dermatitis, is one(More)
Calcium is a crucial regulator of many physiological processes such as cell growth, division, differentiation, cell death and apoptosis. In this study, we examined the effect of cGMP on agonist-induced [Ca(2+)](i) transient in isolated rat aortic endothelial cells. 100 microM ATP was applied to the cells bathed in a Ca(2+)-free physiological solution to(More)
