Here, we demonstrate that the Caenorhabditis elegans pro-longevity factor, NHR-49, also promotes resistance against Pseudomonas aeruginosa, but modulates immunity and longevity by spatially and mechanistically distinct mechanisms. NHR-49 expression is increased by germline ablation, an intervention that extends lifespan, but lowered by pathogen exposure. NHR-49 acted in multiple somatic tissues to promote longevity, whereas, it's pro-immunity function was mediated by neuronal expression. Thus, NHR-49 targets share the largest overlap with genes whose 182 In this study, we demonstrate that NHR-49 is a pro-longevity factor that modulates 368 lifespan and immunity through distinct mechanisms. In fertile, nhr-49 single 393 mutants, immunity was restored by presence in neurons or intestine, but lifespan 394 could be rescued from other tissues as well. elegans lifespan in a NHR-49/PPARalpha-dependent manner ./cache/cord-103343-k4v5ksvq.txt ./txt/cord-103343-k4v5ksvq.txt
