Research Interests
Pulmonary Inflammation and Host Defense
The primary focus of my laboratory is to understand the role of
receptor-mediated signaling upon binding of bacteria and/or their products
in the pathogenesis of inflammatory diseases in the lung. In particular,
we are interested in determining the role of Toll-like receptors (TLRs)
and their adaptors in the development of innate immune response in the
lung in a murine model. We use LPS-derived from bacteria to induce acute
lung injury and use Klebsiella pneumoniae, Streptococcus
pneumoniae, Escherichia coli, Pseudomonas aeruginosa,
and Legionella pneumophila to induce pneumonia. Another focus of my
laboratory is to delineate the role of a neutrophil chemokine CXCL5 in
lung inflammation and host defense. Appropriate gene-deficient mice
and human and murine primary cells are being used. The goal of this research is to resolve the mechanisms by
which these bacteria and/or their products cause inflammation in the lung,
and ultimately to design novel treatment and prevention strategies to
attenuate excessive inflammation.
