Our lab focuses on the mechanisms of microvascular endothelial dysfunction across two lung diseases with high morbidity and mortality: Acute Lung Injury (ALI) and Pulmonary Arterial Hypertension (PAH). Using endothelial cells (ECs) isolated from humans, mice and rats, as well as animal models of ALI and PAH, we investigate the role of elevated reactive oxygen species (ROS) and intracellular calcium in regulating disease-specific abnormalities in EC function. In ALI, we study signaling pathways governing formation of paracellular gaps between endothelial cells, which clinically leads to alveolar flooding and hypoxemia. For PAH, we study the effect of ROS and calcium signaling on EC migration and proliferation as it relates to formation of vaso-occlusive lesions in the distal arterioles of the lung, a known contributor to elevations in pulmonary artery pressures in this disease.
