Wolbachia is an intracellular bacterial symbiont of arthropods notorious for inducing many reproductive manipulations that foster its dissemination. Wolbachia affects many aspects of host biology, including metabolism, longevity and physiology, being described as a nutrient provisioning or metabolic parasite, depending on the host-microbe association. Sirtuins (SIRTs) are a family of NAD+-dependent post-translational regulatory enzymes known to affect many of the same processes altered by Wolbachia, including aging and metabolism, among others. Despite a clear overlap in control of host-derived pathways and physiology, no work has demonstrated a link between these two regulators. We used genetically tractable Drosophila melanogaster to explore the role of sirtuins in shaping signaling pathways in the context of a host-symbiont model. By using transcriptional profiling and metabolic assays in the context of genetic knockouts/over-expressions, we examined the effect of several Wolbachia strains on host sirtuin expression across distinct tissues and timepoints. We also quantified the downstream effects of the sirtuin x Wolbachia interaction on host glucose metabolism, and in turn, how it impacted Wolbachia titer. Our results indicate that the presence of Wolbachia is associated with (1) reduced sirt-4 expression in a strain-specific manner, and (2) alterations in host glutamate dehydrogenase expression and ATP levels, key components of glucose metabolism. We detected high glucose levels in Wolbachia-infected flies, which further increased when sirt-4 was over-expressed. However, under sirt-4 knockout, flies displayed a hypoglycemic state not rescued to normal levels in the presence of Wolbachia. Finally, whole body sirt-4 over-expression resulted in reduced Wolbachia ovarian titer. Our results expand knowledge of Wolbachia-host associations in the context of a yet unexplored class of host post-translational regulatory enzymes with implications for conserved host signaling pathways and bacterial titer, factors known to impact host biology and the symbiont's ability to spread through populations.
