| Research Abstract |
Development of atherosclerosis and unstable plaque, which cause acute coronary syndrome(ACS), are highly associated with chronic inflammation and immunological mechanisms. In this study we found that, (1) in unstable plaque, there are abundant TRAIL-positive CD4 T cells, DR5-positive vascular smooth muscle cells and endothelial cells, and apoptosis of target cells induced through the TRAIL/DR5 pathway, (2) inflammatory cytokine TNFαproduced by CD4 T cells increase DR5 and destabilizes plaque, (3) monitoring of soluble TRAIL in peripheral blood is a potential immunological biomarker for assessing plaque stability and disease severity.
