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 mis-regulated 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.
