High-fat feeding alters serum cytokine levels in mice. Serum cytokine levels of soluble CD30 (sCD30) (A), IL-12p40 (B), IL-22 (C), IL-16 (D), CX3CL1 (E), CXCL1 (F), CCL12 (G), CCL20 (H), tissue inhibitor of metalloproteinase-1 (TIMP-1) (I), CCL4 (J), serum amyloid A-3 (SAA-3) (K), haptoglobin (L), soluble receptor of advanced glycation end-products (sRAGE) (M), A2M (N), and α1-acid glycoprotein (AGP) (O) in mice fed a LFD or a HFD. Data shown are means ± SE (n = 12 per group). *P < 0.05; **P < 0.005.
