Glucose and insulin tolerance.

<p>(A) (IPGTT). Glucose (1 g/kg BW) was administered <i>i.p.</i> to female mice fed an SFD or an HFD. (B) The serum level of insulin 0 min and 120 min after glucose administration (<i>i.p.</i>) to HFD-fed mice was quantified by ELISA. (C) ITT. Insulin (0.75 U/kg BW) was administered <i>i.p.</i> to HFD-fed mice (n = 3–4 female mice in each group). Representative data of three similar experiments are shown. The results are expressed as mean ± s.d. Statistical analysis was performed according to the Tukey-Kramer test. *<i>p</i><0.05 (WT versus CD1d^−/−); ^#p<0.05 (Jα18^−/− versus CD1d^−/−).
