Research interests:

Research in Dr. Vazquez’s lab is focused on the role of non-selective cation channels, such as Transient Receptor Potential Canonical (TRPC) channels and nicotinic acetylcholine receptors, in molecular and cellular events of atherosclerosis. Atherosclerosis is a disease of the arterial wall with a dominant and maladaptive inflammatory response, and represents the leading cause of death in western societies, remaining as the main vascular complication of metabolic diseases such as diabetes, obesity and metabolic syndrome. Our group has recently discovered that endothelial TRPC3 channels are an obligatory component of the signaling underlying regulated expression of cell adhesion molecules and macrophage recruitment to endothelium, two critical events throughout all stages of atherosclerotic lesion development. We have also discovered a novel nicotinic acetylcholine receptor-dependent survival pathway in coronary endothelium. More recently, our lab has shown that TRPC3, through a mechanism not yet defined, is critical for macrophage survival and efferocytosis. To study this, our lab makes use of in vitro (primary and immortalized cell lines) and in vivo (global and conditional transgenic and knockout mice; bone marrow transplantation) models of endothelial and macrophage dysfunction, and a number of techniques (including patch-clamp electrophysiology, real-time camera-based fluorescence imaging, real-time amperometry, protein chemistry/molecular biology, morphometric and immunohistochemical analysis of atherosclerotic lesions in mice).
