Figure 2. Temporal differences in hippocampal cytokine expression following an LPS injection.

Figure 2

Adult male Sprague-Dawley rats were injected with LPS (100 ug/kg) at either ZT6 or ZT16 and hippocampal tissue was collected after 3 or 24 h to evaluate (A) IL1β, (E) TNFα, (C) IL6, (D) IL10 mRNA expression and (E) IL1β, (F) TNFα, (G) IL6, (H) IL10 protein concentrations (n=4). Data are expressed as mean ± SEM. *p<0.05 between ZT16 and ZT6, †p<0.05 between LPS and saline.
