A: Fasting plasma insulin levels were similar between groups (n=7 WT, 6 Ccr2−/−, 6 Cx3cr1−/−, 6 Cx3cr1−/−Ccr2−/−). B: Glucose-induced insulin secretion (2g/kg glucose by intraperitoneal (i.p.) injection) was similar between groups after 13 weeks of HFD. (n=5 WT, 5 Ccr2−/−, 5 Cx3cr1−/−, 5 Cx3cr1−/−Ccr2−/−). C: ITT test showed similar insulin sensitivity between groups (n=11 WT, 9 Ccr2−/−, 9 Cx3cr1−/−, 14 Cx3cr1−/−Ccr2−/−). D: Hyperinsulinic euglycemic clamp was performed in a representative subgroup of mice (n=6 WT, 5 Ccr2−/−, 6 Cx3cr1−/−, 6 Cx3cr1−/−Ccr2−/−). Fasting hepatic glucose production (HGP) and HGP in response to insulin infusion during the clamp were similar between groups. Glucose infusion rate (GIR) required to maintain euglycemia and Rate of Glucose Disposal (Rd) were also not different. Data are mean±SEM. N.S., not significant.
