Figure 3. The effects of C3 deficiency on inflammation and survival after LPS/D-GalN injection.

Figure 3

(A) The response patterns to different ALT concentrations in C3−/− and wt mice (n = 4–5). (B–D) The serum levels of proinflammatory cytokines after LPS/D-GalN injection. The concentrations of TNF-α and IL-6 in the C3−/− mice were lower than in the wt C57BL/6 mice at 1 hour, but the levels of these cytokines in both groups decreased to the same concentrations at later time points. There was no difference in MCP-1 between the groups (n = 4–5). (E) The C3−/− mice had prolonged life spans and an increased survival rate after LPS/D-GalN injection (n = 8). *** indicate p<0.001, in the comparison between the C3−/− and C57BL/6 groups. The means±SEM are shown. The results are representative of 3 separate experiments.
