A subset of integrins (LFA-1, Mac-1, and VLA-4) are expressed on immune cells and play a major role in regulating recruitment of immuno-competent cells to normal or damaged and infected tissues. Under a wide range of pathologic conditions such as autoimmune disease, chronic inflammation, and transplantation rejection, integrin activations are misregulated resulting in abnormal leukocyte trafficking, and direct damage to the vasculature and the underlying host tissue.

Understanding how T cells and neutrophils home to and migrate within tissues is a major focus of our research.
