FIGURE 3.
Pro-inflammatory cytokine expression 24 h after inflammation-sensitized hypoxic-ischemic brain injury. (A) In the hippocampus pro-inflammatory genes of iNOS, IL-1beta and IL-6 were significantly upregulated in animals pre-sensitized with LPS undergoing a mild HI injury. (B) In the cortex, IL-6 was significantly upregulated, whilst IL-12 was downregulated after inflammation-sensitized hypoxic-ischemic brain injury. Group sizes: Sham n = 7, LPS n = 7, Veh/HI n = 12, LPS/HI n = 12; ∗p < 0.05, ∗∗p < 0.01.
