  • Title: The taste of sickness: lipopolysaccharide-induced finickiness in rats.
    Author: Aubert A, Dantzer R.
    Journal: Physiol Behav; 2005 Mar 16; 84(3):437-44. PubMed ID: 15763581.
    Abstract:
    Decrease in food intake is one of the most documented non-specific symptoms of inflammatory processes. However, attention has been mainly focused on quantitative analysis. The present paper reports studies undertaken to test the possible contribution of changes in taste processes in inflammatory-induced alteration of feeding behavior. In a first experiment, the effects of lipopolysaccharide-induced sickness were assessed on preference for saccharin and aversion for quinine in rats using the two-bottle test paradigm. In a second experiment, effect of lipopolysaccharide (LPS) on the behavioral reactivity to palatable, unpalatable and mixed solutions was analyzed using the taste-reactivity paradigm. Our results show that LPS decreased total fluid intake but did not change taste responses to unpalatable or palatable substances. However, LPS increased aversive reactions and decreased hedonic responses to mixed taste. These LPS-induced changes are interpreted as an increase in finickiness and are discussed in regard to their potential role in the adaptation of individuals to sickness.
