In order to identify candidate molecules produced by T. gondii-infected human retinal pigment epithelial cells that might account for the induced proliferation of non-infected neighboring cells, we used RT-qPCR to interrogate ARPE-19 cells 4 and 24 h following infection with GT-1 strain tachyzoites for expression of molecules that are produced by and may impact retinal pigment epithelial cell growth: VEGF, vascular endothelial growth factor B (VEGFB), epidermal growth factor (EGF), IGF1, fibroblast growth factor 1 (FGF1), fibroblast growth factor 2 (FGF2), and TSP1 [16,20,21,22,23,24]. Here, FGF2 is linked to infection.
