IL6 and hydrops fetalis: The HF-FO diet improved the obese phenotype by reducing i) serum hormone concentrations (leptin and resistin), ii) adipose tissue mRNA expression of inflammatory cytokines (MCP-1, IFNγ, IL-6, IL17F and IL-21) and iii) total (F4/80+ CD11b+) and inflammatory adipose tissue M1 (F4/80+ CD11c+) macrophage content compared to HF (P<0.05).
