Proteostasis and resilience in the mechanically-stressed vascular endothelium

Abstract

Endothelial homeostasis is a central feature of vascular health. The vascular endothelium is under constant mechanical stress resulting from blood flow and, therefore, requires a high degree of resilience to adapt to stresses and resist development of disease. In this review, we discuss the molecular mechanisms by which the endothelium maintains proteostasis in response to haemodynamic forces by regulating three key areas: protein synthesis, recycling and degradation.
