18 RESEARCH SUMMARY
39d Our research focuses on the cellular and molecular mechanisms of angiotensin II (AngII) action in the brain. In particular, radioligand binding techniques, quantitative autoradiography, and immunocytochemistry are used to determine the localization of AngII receptors in the central nervous system, and biochemical techniques are then used to determine receptor coupling to ion channels and intracellular effectors such as adenylyl cyclase, nitric oxide syntase and phosphatidylinositol hydrolysis, in cultured neurons. Recent efforts include purification of neuronal AngII receptors, the development of receptor-directed polyclonal and monoclonal antibodies, as well as the cloning of the gene(s) which encode for these receptors. These molecular tools are then used to study the transcriptional and post-translational control of AngII receptor expression as it relates to the behavioral actions of this neuropeptide.
