Serum levels of soluble Fas soluble Fas ligand and soluble IL-2 receptor in patients with coronary heart disease / 浙江大学学报·医学版

ABSTRACT

OBJECTIVE: To evaluate the relationship between serum levels of soluble Fas(sFas), soluble Fas li gand(sFasL), soluble IL-2 receptor(sIL-2R) and coronary heart disease (CHD). METHODS: With enzyme-linked immunosorbent assay (ELISA) tests, sFas, sFasL and sIL-2R were measured in the sera from 30 patients with CHD and 26 subjects without CHD as controls. RESTULTS Mean level of sFas was significantly higher in patients with CHD than in controls [(1 583.41+/-174.46)ng/L compared with (1 374.55+/-142.42)ng/L, P<0.01]. Compared with the controls, the mean level of sIL-2R was significantly higher in patients with CHD [(944.50+/-395.59)ng/L compared with (652.45+/-163.36)ng/L P<0.01]. Moreover, in patients with CHD sFas and sIL-2R were positively correlated (r=0.418 P<0.05). Whereas no such difference was found between both groups in sFasL (P<0.05). CONCLUSION: High levels of serum sFas and sIL-2R were associated with CHD, and elevation of sFas may inhibit apoptosis in activated T cells, leading to coronary events.
