Figure 2From: Toxoplasma gondii prevalent in China induce weaker apoptosis of neural stem cells C17.2 via endoplasmic reticulum stress (ERS) signaling pathways Apoptosis detected by flow cytometry. (A) The C17.2 cells were co-cultured with 5 × 105 TgCtwh3 tachyzoites, heat-inactivated tachyzoites or Apopida (apoptosis inducer A) for 6 h, 12 h, and 24 h; (B) The C17.2 cells were co-cultured with various doses of TgCtwh3 tachyzoites (2 × 104, 1 × 105 and 5 × 105) for 24 h. The cells were then collected, stained with Annexin V/PI, and analyzed by FCM. The plots are from a representative measurement and the graphics represent the mean and S.D. on three different assays (n = 3). * P < 0.05; ** P < 0.01 vs. Negative controls.Back to article page
