Research Description

Our laboratory employs transgenic and knockout mouse models, lineage tracing, isolated human cardiac and vascular tissue, fluorescent and high-resolution imaging techniques, RNA-seq, spatial transcriptomics, and a wide variety of other molecular and biochemical tools to better understand how arterial and venous diseases develop. A major area of focus in the laboratory is to determine the signaling mechanisms regulating macropinocytosis and its role in cardiovascular and other pathologies. We developed a number of animal models, imaging techniques and novel pharmacological and genetic approaches to better understand how this unique endocytic process participates in cardiovascular diseases. Our experiments are conducted in close collaboration with physician-scientists and involve an integrative approach consisting of a wide range of physiological, pharmacological and molecular tools, human cells and tissue and genetically engineered mouse models.

1. To investigate the role of macropinocytosis in macrophage foam cell formation in atherosclerotic arteries.
2. To determine the role of LDL macropinocytosis in phenotypic modulation of vascular smooth muscle cells in atherosclerotic arteries.
3. To examine exosome-mediated intercellular communication between endothelial cells and neutrophils in the development of abdominal aortic aneurysms.
4. To study the mechanisms by which matricellular proteins regulate lymphangiogenesis.
5. To investigate venous smooth muscle cell reprogramming in cardiovascular diseases.
