The evidence shows that endothelial glycocalyx exerts an important role in inflammation and atherosclerosis. We previously demonstrated that hydrodynamic force such as shear stress induces the remodeling of the major component of glycocalyx including glypican-1 with attached heparan sulfate, and that sphingosine-1-phosphate (S1P) protects the glycocalyx against syndecan-1 ectodomain shedding and induces the synthesis of HS. Actually, both shear stress and S1P imposed significant influence on inflammatory disease such as atherosclerosis. Therefore, it can be concluded that glycocalyx is a critical signaling platform for determining the fate of endothelial cells and atherosclerosis. This review integrated our current understanding of shear stress, S1P and glycocalyx, and also provided new insight/issues into the role of the glycocalyx in the process of forming and developing atherosclerosis.
