We examined the effects of glucose, lipid, or fructose infusion on 2-deoxy-D-glucose (2DG)- and 2-mercaptoacetate (MA)-induced feeding. Rats with chronic intra-atrial catheters were infused for 15 min with one of the above nutrients and then injected with 2DG or MA. The nutrient infusion continued for the next 2 h and food intake was simultaneously measured. For control conditions, equitonic saline was infused, and 2DG, MA, or saline was injected. We found that glucose was the only nutrient source capable of significantly reducing 2DG-induced feeding. Equicaloric infusions of lipid or fructose did not significantly reduce 2DG-induced feeding. However, feeding induced by MA was similarly and significantly reduced by glucose, lipid, and fructose. These results suggest that 2DG-induced feeding is mediated by receptor cells that are selectively responsive to glucose availability, and MA-induced feeding is mediated by receptor cells that are responsive to a wider range of metabolic fuels.

D008297	Male		Males
D011956	Receptors, Cell Surface	Cell surface proteins that bind signalling molecules external to the cell with high affinity and convert this extracellular event into one or more intracellular signals that alter the behavior of the target cell (From Alberts, Molecular Biology of the Cell, 2nd ed, pp693-5). Cell surface receptors, unlike enzymes, do not chemically alter their ligands.

D001921	Brain	The part of CENTRAL NERVOUS SYSTEM that is contained within the skull (CRANIUM). Arising from the NEURAL TUBE, the embryonic brain is comprised of three major parts including PROSENCEPHALON (the forebrain); MESENCEPHALON (the midbrain); and RHOMBENCEPHALON (the hindbrain). The developed brain consists of CEREBRUM; CEREBELLUM; and other structures in the BRAIN STEM.	Encephalon
