Loss of SHP2 in macrophages promotes elevated IL-18 secretion and caspase-1 activation both in vivo and in vitro. A and B, after feeding on NCD or HFD for 16 weeks, mice were sacrificed. The levels of IL-1β and IL-18 in the serum were determined by ELISA (A), and caspase-1 (CASP1) activation in peripheral macrophages from mice was determined by Western blotting (B). C–F, Peritoneal macrophages obtained from WT and cSHP2-KO mice were stimulated with 100 ng/ml LPS in the presence of ceramide (0.1 mm) or palmitic acid (PA, 200 μm). The level of IL-18 in the supernatant was determined by ELISA (C and E); CASP1 activation was determined by Western blotting (D and F). Data are expressed as mean ± S.E. in panels A–E, n = 6 in A and n = 3 in C, E. *, p < 0.05; **, p < 0.01.

E, insulin signaling in liver was determined by Western blotting after 6 h fasting. Data are expressed as mean ± S.E. in panels A–E, n = 6-8. *, p < 0.05; **, p < 0.01 versus WT; #, P < 0.05 versus cSHP2-KO in panels A–C. *, p < 0.05 versus values indicated in panels D and E. ns, not significant.

The graphic illustration for the mechanism of SHP2 regulating HFD-induced obesity and insulin resistance. Knockout of SHP2 in macrophage significantly ameliorates HFD-induced obesity and insulin resistance in mice through promoting caspase-1-dependent overproduction of IL-18. IL-18 promotes lipolysis in target tissues and alleviates the whole-body lipid accumulation as well as insulin resistance. More importantly, SHP2-specific inhibitor SHP099 and Phps1 significantly ameliorates HFD-induced insulin resistance and fat liver, indicating a potential drug target for treatment of insulin resistance.
