Antiangiogenic Effect of Platelet P2Y12 Inhibitor in Ischemia-Induced Angiogenesis in Mice Hindlimb
Purpose. Postischemic inflammation induces angiogenesis, while platelet P2Y12 inhibitors can alleviate this inflammation. Therefore, we studied the potential effects of P2Y12 inhibitor, ticagrelor, on angiogenesis in a mouse model of hindlimb ischemia. Methods. Laser Doppler perfusion imaging and ca...

| Summary: | Purpose. Postischemic inflammation induces angiogenesis, while platelet P2Y12 inhibitors can alleviate this inflammation. Therefore, we studied the potential effects of P2Y12 inhibitor, ticagrelor, on angiogenesis in a mouse model of hindlimb ischemia. Methods. Laser Doppler perfusion imaging and capillary density measurement were used for angiogenesis quantified. Immunofluorescence was used to detect the level of CD31. The mice muscle was harvested for enzyme-linked immunosorbent (ELISA) assay of interleukin- (IL) 10 activity and Western blot determination of vascular endothelial growth factor (VEGF) production. Results. Ischemic hindlimb angiogenesis was sharply decreased in IL-10+/+ mice than IL-10-/- mice. Ticagrelor inhibited angiogenesis and blood reperfusion recovery significantly elevated the levels of IL-10 and decreased the expression of VEGF in the IL-10+/+ mouse ischemic hindlimb, which were abolished in IL-10-deficient (IL-10–/–) C57BL/6J mice. Conclusion. The study underscores that the effect of ticagrelor antiangiogenic function is related with the higher IL-10 expression. |
