As for serum cytokines (Figure 4i), cytokine production by macrophages from infected HFD mice at both 1 and 8 weeks post‐infection was significantly less pro‐inflammatory than cytokine production by macrophages from infected ND mice (Figure 6f–g), due to reduced TNF‐α production, but not increased IL‐10 secretion (Figure 6d–e). This evidence concerns the gene IL10 and infection.
