Importance of shear stress
WitrynaRecently, studies have shown that shear stress can regulate the ECs function through the SR-B1-eNOS signaling pathway, thereby influencing the progression of atherosclerosis (Zhang et al., 2016). Thus, regulation of EC SRs by flow shear stress may play a critical role in the formation of EC-derived foam cells. WitrynaShear stress (often denoted by τ (Greek: tau)) is the component of stress coplanar with a material cross section.It arises from the shear force, the component of force vector parallel to the material cross section. Normal stress, on the other hand, arises from the force vector component perpendicular to the material cross section on which it acts.
