KDR and parasitic infectious disease: To further verify the inhibitory effect of SU11248 on the expression of angiogenesis-related factors after parasite infection, we added different concentrations of SU11248 (0.04 μM, 0.1 μM, and 0.5 μM) into the liver cell/protoscolex co-culture system, and the expression of VEGFA, VEGFR2, and p-VEGFR2 was detected by RT-qPCR, western blotting, and ELISA.
