CD44-chondroitin sulfate interactions mediate leukocyte rolling under physiological flow conditions.

Abstract

CD44 on leukocytes binds to its glycosaminoglycan (GAG) ligand, hyaluronic acid, and mediates the rolling of leukocytes on vascular endothelial cells. We previously reported that the recombinant CD44 protein binds to other GAGs, including chondroitin sulfates (CS), although the physiological significance of this interaction has remained unclear. Here we… (More)
