The expression profiles of key Nrf2 pathway components, including Nrf2, xCT, and GPX4, were decreased at both the transcript (NFE2L2, p = 0.009681, xCT, p = 0.000055, and GPX4, p = 0.040776, Figure 2(C)) and protein levels (p < 0.05 or p < 0.01, Figure 2(D)) in the infection group compared to the control group. This evidence concerns the gene GPX4 and infection.
