The National Heart, Lung, and Blood Institute (NHLBI) awarded a 5-year Project Grant totaling $551,863 to The University of Iowa to conduct research on the "Receptor-Mediated Control of Pulmonary Ionocytes" under the Cardiovascular Diseases Research program (CFDA 93.837). The research aims to define the mechanism by which prostaglandin E2 (PGE2) regulates the balance between airway epithelial chloride absorption and secretion to maintain appropriate airway surface liquid volume, a crucial function for respiratory health. The study will pursue specific aims to understand how PGE2 modulates the activity of cystic fibrosis transmembrane conductance regulator (CFTR) channels in ionocytes and secretory cells to control airway liquid dynamics. This innovative research is expected to identify new therapeutic targets for pulmonary diseases.
