Vagal stimulation attenuates hyperglycemia by inducing insulin. (a) Mice were challenged with LPS and received sham or vagal stimulation (VS; 10 Hz, 60 min). Blood glucose levels were analyzed at different time points. *p < 0.05 vs sham (n = 4/group; Two-way ANOVA). (b,c) Mice underwent sham or surgical splenectomy (SPX) 3 days before LPS. Animals underwent control surgery or vagal stimulation (VS), and serum TNF at 1.5 h (b); +p < 0.05 vs LPS (n = 3/group; One-way ANOVA), or blood glucose levels (c) were analyzed. *p < 0.05 vs LPS (n = 4/group; Two-way ANOVA). (d) Fasted mice received sham or vagal stimulation (VS), and serum insulin levels were analyzed at the indicated time points. *p < 0.05 vs LPS (n = 4/group; Two-way ANOVA). (e,f) Fasted mice underwent sham or surgical pancreatectomy (PX) 1 day before LPS, underwent sham or vagal stimulation, and blood insulin (e) or glucose (f) levels were analyzed at 1.5 h post-LPS. +p < 0.05 vs LPS (n = 4/group; One-way ANOVA).
