Regulation of the macrophage inflammatory phenotype in ARDS
In this proposed research, we will examine the role of NFAT on EV lipid and protein content and their role in mediating permeability pulmonary edema (ARDS) in the clinically relevant mouse models. Our supportive data show that NFATc3 regulates expression of cytoplasmic phospholipase A-2 (cPLA2) and cyclooxygenase-1 (COX-2) that are associated with changes in the lipid content of EVs and that NFATc3 dependent proteins and lipids disrupt the permeability barrier in culture pulmonary microvascular endothelial cells.
