KDR and infection: In Figure 2A and B, we demonstrate that at seven days post-TMEV infection, there is significantly increased expression of flk-1 mRNA in the hippocampus (n = 4 for both sham and TMEV infected animals, P = 0.016) and striatum (n = 4 for both sham and TMEV infected animals; P = 0.025) when compared to sham controls, in which sterile PBS is intracranially administered to the brain.
