mDIO is associated with pro-inflammatory TLR signaling and a pro-inflammatory macrophage phenotype in the placenta. (A) Relative mRNA levels of toll-like receptor 2 (Tlr2), toll-like receptor 4 (Tlr4), TNF receptor-associated factor 6 (Traf6), nuclear factor kappa B (Nfκb), tumor necrosis factor (Tnf), interleukin 6 (Il6), and interleukin 10 (Il10) in placentae of control and high-fat dams. (B) Relative mRNA levels of pro-inflammatory macrophage cell markers, chemo-attractants, and polarization factors; F4/80, monocyte chemoattractant protein 1 (Mcp1), colony stimulating factor 1 (Csf1), colony stimulating factor receptor 1 (Csf1r), colony stimulating factor receptor 2 (Csf2r), arginase 1 (Arg1), nitric oxide synthase 2 (Nos2), and the ratio of Nos2 to Arg1 in placentae of control and high-fat dams. Representative images of F4/80 positive macrophage immuno-localization in the placenta of control and high-fat dams (females are shown). Scale bar represents 100 µm. Main effects are written as text in the figure. Data were analyzed with a 2-way ANOVA with Bonferroni’s post-hoc multiple comparisons test. Control: open boxes, (n = 7) and high-fat: grey boxes, (n = 9). *p < 0.05.
