Effects of T. gondii ME-49 on Jurkat T-cell and Molt-4 T-cell proliferation and apoptosis in different concentration tachyzoites. a Tunel assay was used to detect the effect of T. gondii ME-49 on apoptosis of Jurkat T-cells and Molt-4 T-cells. b, c Effects of T. gondii ME-49 (5 × 106 cells/ml) on Jurkat T-cell and Molt-4 T-cell proliferation. d, e Flow cytograms of cell apoptosis of cells infected with T. gondii ME-49 (5 × 106 cells/ml). Q4, early apoptosis; Q2, late apoptosis. Values are presented as the mean ± SD (n = 3). *P < 0.05 vs the control group
