Description of Research Expertise

The lung has an immunoprotective, hyporesponsive environment that helps prevent inappropriate immune and inflammatory responses to inhaled toxic, infectious or allergenic material. The long-term goal of my research is to unravel the the mechanisms that impair the innate and adaptive immune crosstalk during development of allergic and infectious inflammatory changes in the lung. To investigate T-cell related pathologies such as the allergic airway response my laboratory has established various in vitro and in vivo (rodent) model systems suitable to study pulmonary inflammation as well as the resulting changes in lung physiology. My laboratory is one of the few that study the importance of the pulmonary surfactant and in particular, the lung collectins, (SP-A and SP-D), in asthma and chronic obstructive pulmonary disease. Our observations support the novel concept that these lectin-like innate immune molecules play an essential protective regulatory role during inflammatory changes. Our studies are important because they may provide unique, novel therapeutical opportunities to control and manipulate the immune system in the lung.

Description of Itmat Expertise

My laboratory was one of the few that originally raised the importance of lung collectins (SP-A and SP-D) in innate immune regulation of the inflammatory airway response in asthma and the one that discovered a feedback regulatory circuit between Th2 cytokines and SP-D. SP-D has a potent immunoprotective function and maybe used for therapeutic purposes in disease conditions such as COPD and cystic fibrosis where low SP-D levels worsen the outcome. We study the effects of air pollution (ozone exposure) on lung physiology and innate immune regulation of airway inflammation in asthma, COPD and influenza A virus infection. We are interested in the role of Fas ligand (death receptor) in apoptosis and of RELM-(resistin-like molecule) beta in extra cellular matrix deposition. We model social stress and cigarette smoke exposure in mice in vivo and study the alterations in lung epithelial and immune cell signaling networks, including glucocorticoid receptor related pathways.
