T Lymphocyte-Derived Exosomes Transport MEK1/2 and ERK1/2 and Induce NOX4-Dependent Oxidative Stress in Cardiac Microvascular Endothelial Cells

Figure 9

Schematic presentation of proposed mechanism. Activated T lymphocytes shed exosomes containing ERK1/2 and MEK1/2 kinases. These exosomes taken up by endothelial cells cause upregulation of NOX4 leading to oxidative stress and enhanced proliferation.
