Fasting and refeeding alters serum cytokine levels in mice. A–L: serum cytokine levels of granulocyte colony-stimulating factor (G-CSF), IL-22, IL-1α, IL-1β, secreted IL-1 receptor type 1 (sIL-1RI), soluble IL-2 receptor α chain (sIL-2Rα), chemokine (C-C motif) ligand 2 (CCL2), lipocalin-2, pentraxin-3, soluble vascular endothelial growth factor receptor 3 (sVEGFR3), tissue inhibitor of metalloproteinase-1 (TIMP-1), and serum amyloid protein (SAP) in fasted and refed mice. Data are expressed as means ± SE (n = 10 per group) *P < 0.05; **P < 0.005.
