Resumen:
Several lines of evidence suggest that learning and triggering an immune response are both metabolically expensive and thus likely to be subject of nutritional trade-offs between them and other competing demands. Therefore, we evaluated if an immune challenge with a novel antigen affects spatial learning in the subterranean rodent Ctenomys talarum under two different dietary conditions. The results showed that immune-challenged animals were affected in their spatial learning capabilities, increasing the number of errors (GLM, n=47, F=4.85, p=0.032) and marginally the latency (GLM, n=47, F=3.34, p=0.07) to reach the goal of a complex labyrinth. No effect of the dietary restriction (latency p=0.43, errors p=0.11) nor interaction between factors were observed (latency p=0.86, errors p=0.95). This work provides support for the existence of a trade-off between the costs of the immune defense and learning abilities, while absence of effect of nutritional condition on this trade-off suggests that the relationship among these factors is more complex than supposed.
