To determine the specific thrombotic and inflammatory contributions of platelet-expressed CD40 ligand (CD40L) during the progression of atherosclerosis.
Assessed in vitro aggregation and thrombus stability using CD40L-deficient (Cd40l−/−) platelets.
Injected activated wild-type or Cd40l−/− platelets repeatedly into atherosclerosis-prone Apoe−/− mice to evaluate vascular adhesion, plasma CCL2 levels, and lesion formation.
Measured regulatory T-cell (Treg) populations and evaluated the effects of experimental Treg depletion on lesion development.
Cd40l−/− platelets exhibited impaired aggregation, reduced thrombus stability, and an inability to form proinflammatory platelet-leukocyte aggregates.
Injections of Cd40l−/− platelets into Apoe−/− mice markedly reduced endothelial platelet and leukocyte adhesion, decreased plasma CCL2 levels, and prevented lesion formation compared to wild-type platelets.
Wild-type platelets transiently reduced blood and splenic Tregs, and antibody-mediated Treg depletion eliminated the athero-protective benefit seen with Cd40l−/− platelets.
