Figure 2. Interaction of intracerebroventricular injection of either agouti-related protein (AgRP) or saline with i.v. injection of either saline or endotoxin (lipopolysaccharide, LPS) on cumulative feed intake in sheep. Saline or AgRP was injected intracerebroventricularly (indicated by arrow on graph) 1 h before i.v. injection of saline or LPS (indicated by arrow on graph). *Feed intake was decreased by LPS vs. other groups (P < 0.05); n = 5.
