Figure 4. IL-6KO mice have increased monocyte/macrophage infiltration into the heart at 7 days post infection.
Heart infiltrate was measured by flow cytometry analysis at 7 days post treatment with CB3/LPS. Cardiac infiltrate determined based on forward and side scatter as well as CD11b and CD11c immunostaining. IL-6KO mice had significantly increased monocyte/macrophage infiltration at 7 days post treatment compared to wt mice (C57BL/6 n = 9, IL-6KO n = 11) (black bars indicate wt mice, white bars indicate IL-6KO mice) (mean±SE, *p<0.05). This increased correlated with the elevated levels of the chemokine MCP-1 in IL-6KO mice and suggests a link between these two factors.
