I have been focused on defining the mechanisms that contribute to chronic lung inflammation and fibroproliferation in the absence of infection.

1.  Extracellular matrix and lung injury. My major research focus has been defining the role of the extracellular matrix glycosaminoglycan hyaluronan (HA) in lung inflammation. I was the first to show that HA could induce growth factors and identified a novel signaling pathway in macrophages. I showed that HA had to be modified by the inflammatory milieu to function as a signaling molecule. We then defined the role of the HA cell surface receptor CD44 in lung inflammation. CD44 is required to remove fragmented HA from injured lungs and prevent death from unremitting inflammation. We then showed that matrix could initiate innate immune responses when Toll-like receptors 2 and 4 were able to recognize fragmented HA in vivo. In addition we discovered that HA has different functions when interacting in a soluble form with macrophages or on the cell surface of lung epithelial cells where it is bound to TLR2 and TLR4. We were the first to show that cell surface HA on lung epithelial cells has a protective role against lung injury by interacting with TLR2 and TLR4 similar to how gut bacteria are protective against tissue injury. Our lab is using genetically modified mouse models in which hyaluronan synthases, hyaluronan degradation enzymes, and hyaluronan binding proteins have been knocked out or overexpressed.

2.  Role of chemokines and chemokine receptors in lung injury and repair. I was also the first to describe a critical role for interferon-gamma produced by NK cells in limiting tissue fibrosis following non-infectious lung injury. We are working the immunoregulatory and molecular roles of CXCL10, CXCR3, CXCL12, and CCL2 in lung injury and repair.

3.  Idiopathic Pulmonary Fibrosis.
