Research Interest

Calcium as a second messenger Ion channels Exocytosis in mast cells The structure and function of the receptor for immunoglobulin E Cell activation and signal transduction BRIEF DESCRIPTON OF RESEARCH: The role of calcium in stimulus-response coupling. Elucidation of the mechanisms by which receptors in the immune system transduce signals. Biophysical, biochemical and pharmacological approaches have been used to study the receptor for immunoglobulin E on mast cells and the mechanisms by which activation of this receptor leads to an increase in intracellular calcium and the release of mediators of immediate hypersensitivity. Techniques included using fluorescent and luminescent probes to measure intracellular Ca2+ and membrane potential, fluorescence imaging of intracellular Ca2+ in individual cells, patch clamp electrophysiology, single cell amperometry and radioactive ion flux assays.
