Sialyl-Lewis is important in leukocyte tethering and rolling. Leukocytes move through the blood stream and then tether themselves to the endothelial wall and roll along the endothelial tissue to determine if they want to leave the bloodstream to get to necessary tissue. Sialyl-Lewis is a necessary partner for the three selectins that bind the leukocyte and endothelial cells.
