The IVPP study section reviews applications focused on endothelial cells, blood vessels and lymphatics and their role in normal physiology and disease. Cellular, biochemical, biophysical, immunological, genetic, pharmacological, and molecular biological approaches are typical. Basic and applied aspects of cardiovascular regulation are reviewed that focus on the physiology of blood pressure regulation, the pathogenesis of hypertension and the microcirculation, biology of the endothelium and vascular smooth muscle cells and vascular homeostasis and dysfunction in experimental models. Studies on cell surface receptors and signaling processes of various hormones, paracrines, and autocrines and their mechanisms of action as related to hypertension, integrated neural-humoral control of circulation, regional hemodynamics, lymphatic circulation, and microcirculation are also considered.
