BAX and infection: The result showed that Bax (t-test: t(4) = 4.49, P = 0.0109) and caspase 3 (t-test: t(4) = 4.834, P = 0.0084) were enhanced, while Bcl-XL (t-test: t(4) = 6.743, P = 0.0025) was diminished, implying TgCtwh6 infection could provoke hippocampal cells, probably including neuron apoptosis (Fig. 2D–G).
