OBJECTIVE: Atherosclerotic plaque development is closely associated with the hemodynamic forces applied to endothelial cells (EC). Among these, shear stress (SS) plays a key role in disease development since changes in flow intensity and direction could stimulate an atheroprone or athero...

Lymphatic valves are specialized units regularly distributed along collecting vessels that allow unidirectional forward propulsion of the lymph, and its efficient transport from tissues to the bloodstream. Lymphatic endothelial cells that cover lymphatic valve sinuses are subjected to complex flow p...

The mechanisms by which oscillatory shear (OS) induces, while high laminar shear stress (LS) prevents, atherosclerosis are still unclear. Here, we examined the hypothesis that OS induces inflammatory response, a critical atherogenic event, in endothelial cells by a miRNA-dependent mechanism. In part...

Oscillatory shear stress induced extracellular vesicles mediate valvular endothelial-interstitial cell crosstalk exacerbating aortic valve calcification
Endothelial cells (EC) are key regulators in vascular homeostasis, and their physiological state depends on hemodynamic forces produced by the blood flow. Laminar shear stress (LSS) maintains endothelial integrity, whereas oscillatory shear stress (OSS) leads to endothelial dysfunction and subsequen...

G3BP2 in Oscillatory Shear Stress-induced Atherosclerosis
Atherosclerosis is an important pathological factor in the development of cardiovascular diseases. In addition to increased plasma lipid concentrations, irregular/oscillatory shear stress and inflammatory processes trigger pathophysiological changes. Inhibitors of the transcription modulatory bromo-...

HUVECs transfected with siRNA targeting Neuropilin 1(NRP1) (si-NRP1) or a control non-targeting sequence (si-control) and exposed to unidirectional shear stress (20dyns/cm2), oscillatory flow (5dyn/cm2) or kept in absence of flow.
