The expression of Uqcrq, Cox4i1, Ndufb8, Atp6v1g2 and Atp5b involved in oxidative phosphorylation was upregulated in CM-R mice on day 2 post-infection [see Additional file 2], suggesting that cerebral oxidative metabolism may be stimulated by PbA infection in CM-R mice. Here, COX4I1 is linked to infection.
