Research Interests

My laboratory studies lung vascular biology and immuno-pathogenesis of acute lung injury. Our research focuses on the mechanism of respiratory virus-induced lung vascular injury and signals between endothelial cells and immune cells during the innate and adaptive immune response. The SARS-CoV-2 and H1N1-induced acute lung injury models are two major animal models used in the laboratory. We are also interested in lung vascular regeneration and mechanisms of transcriptional regulation in the vasculature. By understanding the mechanisms which regulate the balance between inflammatory injury and regeneration in viral lung injury, we will be able to develop new therapies that minimize inflammatory injury, maximize tissue repair and reduce patient mortality.

Projects

Project 1: To explore endothelial antigen presentation to T cells as a pathogenic mechanism in influenza-induced acute lung injury.

This NIH funded project is to explore the potential pathogenic roles of endothelial antigen presentation to T cells as well as the interplay between regenerative and inflammatory mechanisms in the lung endothelium.

Project 2: To elaborate the mechanism of novel engineered high affinity ACE2 peptides for distinct SARS-CoV-2 variants-induced acute lung injury and long COVID.

The emergence of SARS-CoV-2 variants of concern escaping vaccine-induced immune responses highlight the urgency for novel COVID-19 therapeutics. Novel engineered ACE2 peptides have been proved to be especially efficacious against multiple variants. Its dual mechanisms of action: direct blocking of viral S and turnover of ACE2 substrates associated with lung injury and inflammation will be further elaborated using the animal models of SARSC-CoV-2-induced acute lung injury and long COVID.

Project 3: To investigate the pathogenic role of lung microvascular endothelial cells in long COVID.

Long COVID or post-acute sequelae of SARS-CoV-2 infection is a condition that the COVID-19 patients with severe COVID19 or mild COVID-19 develop a variety of symptoms and clinical findings 4 or more weeks after infection. The pathophysiology drivers of Long COVID are completely unknown. This project investigates the pathophysiology drivers by focusing on lung microvascular endothelial cells and its signal interactions with macrophages and fibroblasts to induce the long COVID.
