Inflammation is linked to motivational deficits seen in depression and other disorders. Lipopolysaccharide (LPS) induces an inflammatory response and impairs motivated behavior in humans and rodents. It has been suggested that inflammation can shift metabolic needs to functions that warrant more response to the perceived threat (e.g., fighting infection), therefore altering aspects of motivation. Animal models have been developed to assess alterations in motivated behavior by giving the animal the option to work (i.e., lever press) for a highly palatable food reward vs. approaching and consuming a freely available, albeit less preferred, food. This model was used to determine if administration of 2-deoxy-D-glucose (2DG), a substance that inhibits glucose uptake and glycolysis, could reverse the motivational deficits induced by LPS in rats. A food preference/intake task was also conducted to see if LPS affected intake of the highly palatable vs. less palatable foods when both are freely available. It was hypothesized that 2-DG would reverse the motivational deficits caused by LPS and there would be no effect on food preference/intake of the highly palatable food. Results showed that 2-DG significantly reversed LPS effects at the lowest dose, while methylphenidate did not. The food intake/preference tests showed that LPS significantly decreased food intake of both foods but did not alter preference for the highly palatable food compared to vehicle. These results suggest that in addition to having effects on exertion of effort during instrumental behavior, LPS also has direct effects on primary food motivation.
