Interleukin-6 knockout reverses macrophage differentiation imbalance and alleviates cardiac dysfunction in aging mice
Figure 1. Effect of aging on cardiac IL-6 expression. (A) The expression of IL-6 in mice at 3 months, 15 months, 20 months, and 25 months of age was measured by Western blotting. N=5 in each group. * p<0.05 vs. the 3-month group. # p<0.05 vs. the previous group. (B) Plasma sIL-6R and sgp130 levels were detected in each group. N=5 in each group. * p<0.05 vs. the 3-month group. # p<0.05 vs. the previous group. (C) Effects of DOX treatment on IL-6 mRNA expression in WT Møs, lymphocytes, DCs, MCs, and CFs. N=5 in each group. * p<0.05 vs. the group. (D) The cardiac expression of both IL-6 and Mø markers in mice of different ages was detected in 25-month-old mice by immunofluorescence staining. N=5 in each group. (E) Double immunofluorescence staining for anti-F4/80 and anti-IL-6. N=5 in each group.
