During infection or injury, white blood cells (leukocytes) must exit from the circulation to reach sites in the tissue where they are needed to mount an immune response. My lab's focus is on the neutrophil, a type of innate immune cell that is the first to mobilize from the circulation to mount the inflammatory response. The recruitment of neutrophils occurs by a cascade of interactions with the endothelial cell lining of the blood vessel wall that precedes their migration into the tissue. We use biophysical and molecular engineering methods to dissect the mechanisms of leukocyte capture, rolling, arrest, adhesion stabilization and intravascular migration. Our research also uses CRISPR-based gene editing to identify novel aspects of neutrophil function and thereby develop strategies for combating drug-resistant bacterial and fungal infections.
