NIH/NHLBI Protein Regulation and Cytoskeletal Dynamics of Pulmonary Endothelial Barrier Function
This project focuses on the characterization of a three cytoskeletal regulatory proteins, myosin light chain kinase, cortactin and the Arp 2/3 complex and their integrated role in generating endothelial cell membrane structures to ultimately determine barrier function. The goal of this research is to better understand the pathophysiologic mechanisms responsible for pulmonary vascular leak and recovery of barrier function in ARDS.

Role of NFATc3 in Altered Hypoxic Pulmonary Vasoconstriction during Acute Lung Injury
Lung inflammation and hypoxemia are major risk factors for mortality in acute respiratory distress syndrome (ARDS). Adequate blood oxygenation is dependent on effective matching of ventilation and perfusion in the lung microenvironment and, as an evolutionary mechanism, hypoxic pulmonary vasoconstriction is aimed at maintaining sufficient blood supply to the most effectively ventilated areas of the lung. The purpose of this proposal is to determine the mechanisms by which NFATc3 leads to impaired HPV during acute lung inflammation and injury.

NIH R01 1R01HL126852-01A1 (PI: Gye Young Park, 25% effort)
Role of alternatively activated macrophages in allergic asthma
3/1/16-12/31/20 3.1 cal months Annual direct costs $262,7290
The major goals of this project are to examine the details of the cellular and biochemical steps of inflammation in alveolar macrophage cells which are likely to be responsible for the chronic refractory asthma. The proposed study could lead to a better understanding of the pathogenesis of asthma, which will eventually improve management of asthma.
Respiratory Health Association Lung Cancer Research Award (PI: Gye Young Park, 5% effort)
Macrophage regulation of lung cancer progression
7/1/16-6/30/18 0.6 months Annual direct costs $62,500
The major goals of this proposed study will investigate a new approach of immunotherapy to transform tumor-associated macrophages (TAMs) into a new phenotype that is less favorable for tumor growth. In this proposed study, we want to examine a highly innovative hypothesis which could lead to the development of a new immunotherapy against lung cancer.

The Chicago Collaborative to Promote and Advance Cancer Health Equity
The presence of major cancer health inequities in Chicago is well-documented. This proposed 3 institutional partnership poses a strong and important approach for reducing deeply-engrained disparities. CCPACHE is a partnership in research, education, and community outreach aimed directly at building and fostering the next generation pipeline of students and faculty entering health-related careers, increasing the number of cancer health disparities researchers, and facilitating the translation of cancer research that is directly informed by, and relevant to, Chicagoland communities most impacted by cancer disparities.
