Cyanidin-3-o-β-glucoside Inhibits THP-1 Cells Migration Mediated by Platelet Derived Chemotactic Factor
摘要
Abstract
[Objective]To evaluate the effects of anthocyanin cyanidin-3-o-β-glucoside(Cy-3-g)on monocyte migra-tion mediated by platelet derived factors in vitro.[Methods]Thrombin-activated human gel-filtered platelets were incubated with different concentrations(0,0.5,5 or 50 μmol/L)of Cy-3-g.The level of TGF-β1,β-TG,CCL5 in platelet superna-tant was determined by ELISA.The peripheral venous blood from healthy volunteers were incubated with different concentra-tions of Cy-3-g. The expression of CCR5 on leukocytes was detected by flow cytometer. Calcein AM labeled THP-1 cells were incubated with the releasates of Cy-3-g-treated gel-filtered platelets for 120 min,and then the number of the THP-1 cells were counted by a microscope.Moreover,THP-1 cells were pre-incubated with different concentrations of Cy-3-g with or without CCR5 inhibitor maraviroc(200 μmol/L)for 60 min,then treated with recombinant CCL5(100 nmol/L)for 120 min.The number of the THP-1 cells were counted as well.[Results]Cy-3-g significantly inhibited platelet TGF-β1,β-TG,CCL5 secretion and decreased CCR5 expression of leukocytes compared with the control(P<0.05).Moreover,the sig-nificant inhibitory effects of Cy-3-g on THP-1 cell migration toward the releasates of Cy-3-g-treated platelets were also ob-served(P<0.05). In addition,THP-1 cell migration toward recombinant CCL5 was significantly suppressed by Cy-3-g.[Conclusions]Anthocyanin Cy-3-g inhibited inflammation of atherosclerosis by platelet TGF-β1,β-TG,CCL5 secretion and CCL5-mediated monocyte migration.Our results provided new ideas for prevention and treatment of atherosclerosis.关键词
