Thrombolytic therapy on function of Th17 and Treg in patients with myocardial infarction / 中国免疫学杂志

ABSTRACT

Objective:To investigate Th17,Treg and related factors before and after myocardial infarction ,and explore the cor-relations among them.Methods:Extracted mononuclear cell in peripheral blood ,and used fluorescence-activated cell sorting analysis to detect the contect of Th17 and Treg.Enzyme-linked immunosorbent assay was used to detect cytokine production of IL-17 and TGF-β;real-time PCR was used to detect the contect of RORγT and Foxp3.Results: Compared with the control group , experimental group (both before and after thrombolysis) had increased expressions of Th17,IL-17 and RORγT(P<0.05);the expressions of Treg,TGF-βand Foxp3 had decreased(P<0.05).Compared with the group of before thrombolysis ,the group of after thrombolysis 7 d had decreased expressions of Th17,IL-17 and RORγT(P<0.05);increased expressions of Treg,TGF-βand Foxp3(P<0.05).Conclusion:Compared with the control group,patients with myocardial infarction have the high levels of Th 17 and the related factors,the decreased levels of Treg and the related factors.Thrombolytic therapy can decrease the levels of Th 17 and the related factors,and increase levels of Treg and the related factors.
