Interests
Pulmonary fibrosis encompasses several fatal environmental and occupational lung diseases for which there is currently no effective treatment strategy. More subtle fibrotic reactions also contribute to chronic airway remodeling observed in individuals with asthma, bronchitis, and chronic obstructive pulmonary disease (COPD). A common theme in the progression of fibrosis is the emergence of fibroblasts, connective tissue cells which proliferate and deposit collagen to define the fibrotic lesion.
 
Our laboratory studies the cellular and molecular mechanisms through which toxic environmental agents such as particles, nanoparticles, and metals cause fibroblast growth or matrix production resulting in fibrosis. Using a variety of molecular techniques, genomics and transgenic mouse models we have identified intracellular signaling pathways and novel genes that contribute to the progression of fibrosis. Our research has focused mainly on two families of cell surface growth factor receptor tyrosine kinases (RTK) that mediate these cellular responses: the platelet-derived growth factor receptor family (PDGFR) and the epidermal growth factor receptor family (EGFR). We have identified these RTKs as potentially important targets for therapeutic intervention of pulmonary fibrosis.


The emerging field of nanotechnology has prompted new initiatives aimed at understanding the possible health effects of manufactured nanomaterials (carbon nanotubes and nano-sized metal catalysts). Our goal is to determine the physico-chemical properties of nanomaterials that trigger fibrotic reactions in the lung in order to provide information for the design of safer nanomaterials. Of particular interest is determining the fibrotic potential of nanomaterials in mouse models of pre-existing lung disease such as asthma, viral infection, and bacterial endotoxin-induced inflammation.
