Relative mRNA expression profiles of IL-1β, TNF-α, IL-6, COX-2, and iNOS in the hippocampus. The deficiency of PKR had minimal effect on inflammatory gene expression in the hippocampus after E. coli challenge. n = 7–8 per group at 4 h, n = 6–8 per group at 48 h, and n = 9–11 per group at 120 h. *p < 0.05, **p < 0.01, ***p < 0.001
