Atherosclerosis, the major cause of death and illness in industrialized nations, develops in regions of arteries in which fluid flow patterns are disturbed and endothelial cells fail to align in the direction of flow. In contrast, regions of laminar flow in which cells are aligned are protected. The current work shows that the transmembrane proteoglycan syndecan 4 is required for endothelial cell alignment in the direction of flow and for the protective effect of high laminar flow, yet other flow responses are intact. The data therefore identify a role for syndecan 4 in flow direction sensing, show that sensing flow direction is separable from sensing flow magnitude, and provide new support for the key role of cell alignment in atheroprotection.
