摘要：

Background and Aims. There is an imbalance between Th1 and Th2 in the development and progression of atherosclerosis and in patients with acute coronary syndrome (ACS) including acute myocardial infarction (AMI) and unstable angina. T helper cell type 3 (Th3), which primarily secretes transforming growth factor beta-1 (TGF-beta 1), has been shown to inhibit both Th1 and Th2 cells. The present study was designed to investigate whether TO cells are involved in plaque destabilization and the onset of ACS. Methods. Ninety one patients who underwent diagnostic catheterization were classified into four groups (AMI group, unstable angina group, stable angina group and chest pain syndrome group). The cell frequencies of Th1, Th2 and Th3 were detected using flow cytometry, and the concentrations of their related cytokines IFN-gamma, IL-4 and TGF-beta 1 were studied by ELISA. Results. Apart from the imbalance between Th1 and Th2, results revealed a significant decrease in peripheral TO number and levels of TGF-beta 1 in patients with ACS as compared with those in patients with stable angina and chest pain syndrome (p<0.01). Conclusions. Downregulation of Th3 cells in patients with ACS may play a potential role in plaque destabilization and the onset of ACS. (C) 2009 IMSS. Published by Elsevier Inc.
