Fig. 1From: Effects of gut-derived endotoxin on anxiety-like and repetitive behaviors in male and female miceOral gavage of LPS produces low-grade endotoxemia. Serum LPS levels in WT mice treated with saline (blue bar) or LPS (green bar). LPS treatment significantly increased LPS levels 1.5-fold, 2Â h after gavage. Bars indicate mean and 95% confidence intervals. *p < 0.05Â Back to article page
