ABSTRACT
To investigate the role of anti-inflammatory cytokine in acute coronary syndrome (ACS), the effect of IL-10 on expression of tissue factor (TF) induced by IL-6 in peripheral blood mononuclear cells (PBMNC) were studied. PBMNC were allowed to culture with rhIL-10 before being stimulated by rhIL-6. One-step recalcification clotting time was used to evaluate procoagulant activity (PCA) of PBMNC. The expression and activity of TF protein were determined by ELISA and cell chromogenic substrate assay. The results showed that the expression of PCA, TF protein and its activity in PBMNC increased significantly after being stimulated by rhIL-6 (P < 0.01). In PBMNC, rhIL-6-induced PCA was regulated by rhIL-10 in different doses. This effect was associated with reduction of TF protein expression and activity by rhIL-10 (P < 0.01). In conclusion, IL-10 down-regulated expression PCA and TF in PBMNC, inhibitory effect of IL-10 on expression and activity of PBMNC TF may be important protective mechanism for ACS, regulation imbalance between inflammatory and anti-inflammatory cytokines may be important factor participating in coronary thrombosis.
