Research Interests

Acute lung injury (ALI), a significant cause of morbidity and mortality in the critically ill patient population, affecting 200,000 patients per year in the US and poses a mortality risk of 29–42%. ALI is an acute inflammatory disorder that compromises the integrity of the vascular barrier and disturbs tissue fluid homeostasis. Cellular characteristics of ALI include loss of alveolar–capillary membrane integrity, excessive transendothelial neutrophil migration, and massive release of pro-inflammatory cytotoxic mediators from activated neutrophils and macrophages. I am currently investigating the role of macrophage plasticity in modulating acute lung injury response and signaling mechanism of PMN transmigration across vascular barrier in septic conditions in two different projects as described below:


1. We recently identified an important role of TNF-alpha stimulated-gene-6 (TSG6) in suppression of endotoxin induced lung vascular injury in switching a phenotypic shift in macrophages from pro-inflammatory to anti-inflammatory phenotype (PNAS, 2016). We are currently investigating if the TSG6 treated polarized macrophages with M2 phenotype could be used as a cell based therapy to treat endotoxin induced acute lung injury in mouse model.


2. The role of Calcium and ROS signaling in PMN transmigration in inflammatory conditions has been reported in a number of studies. However, the identity of the calcium channel in endothelial cells that mediate PMN transmigration remains elusive. By genetic approach, we have created an inducible endothelial cell specific knockout mouse model, where a ROS activated Trp melastatin channel-2 (Trpm2) could be deleted in the vascular beds by tamoxifen injection. These mice when subjected to endotoxin challenge exhibit impaired PMN transmigration and shows a significant survival advantage compared to the WT mice. By understanding the pathophysiology of TRPM2 channel in inflammatory disease conditions, we will be able to design novel inhibitors in future to combat PMN transmigration and reduce mortality occurring from sepsis.
