Signaling of endothelial cytoprotection in transplantation

Abstract : A better knowledge of the processes by which endothelium can resist to cell death and adapt to injury by specific intracellular signaling pathways and dedicated protein regulation is a key step to understand how vascular inflammation/injury develops and how it is regulated. This review focuses on signaling pathways and molecular effectors that trigger the balance between endothelial cell activation and dys-function. In addition to the canonical nuclear factor-jB (NF-jB), phosphatidyl inositol 3-kinase (PI-3K) and mitogen-activated protein kinases (MAPK) that orchestrated the inflammatory response and its termination we report here additive pathways such as Notch pathway and protein C/protease activated receptor (PAR) pathway that have been also reported to play a role in the control of EC activation and apoptosis. This review also provides an update of the characteristics of some established and novel protective molecules for the endothelium, identified in transplantation.
