Ghrelin's actions on food CPP require intact orexin signaling. A. Orexin 1 receptor antagonist (SB-334867, 10 μg/g BW, i.p.)-pretreated mice and orexin-deficient mice fail to demonstrate ghrelin-induced acquisition of food CPP. B. SB-334867-pretreated and orexin-deficient mice show similar ghrelin-induced increases in food intake for both HFD and RC after 30 min of treatment. Data represent the mean ± s.e.m. ****, p<0.00001.
