Upper panel: Proposed translational strategy for improved anti-inflammatory therapy using CD40–CD40L-antagonizing approaches. Lower panel: Key mechanisms of inflammation, atherothrombosis, oxidative stress and endothelial dysfunction. Improvement of these adverse key mechanisms by CD40(L)/TRAF inhibition. siRNA, small interfering RNA; ASOs, antisense oligonucleotides; TRAF-STOPs, inhibitors of TNF receptor associated factor; ECs, endothelial cells; VSMCs, vascular smooth muscle cells; NOX2, phagocytic NADPH oxidase (gp91phox); NOS2, inducible nitric oxide synthase; AGE, advanced glycation end products; RAGE, receptor for AGE; LDL, low density lipoprotein; WBC, white blood cell.
