Intrinsic innate immune mechanisms are the first line of defense against pathogens, and exist to control infection autonomously in infected cells. Here we show that autophagy, an intrinsic mechanism that can degrade cytoplasmic components, plays a direct anti-viral role against the mammalian viral pathogen Vesicular Stomatitis Virus (VSV) in the model organism Drosophila. We found that the surface glycoprotein, VSVG, is likely the pathogen-associated molecular pattern (PAMP) that initiates this cell-autonomous response. Once activated, autophagy decreases viral replication, and repression of autophagy leads to increased viral replication and pathogenesis in cells and animals. Lastly, we show that the antiviral response is controlled by the phosphatidylinositol 3-kinase (PI3K)/Akt signaling pathway which normally regulates autophagy in response to nutrient availability. Altogether these data uncover an intrinsic antiviral program that that links viral recognition to the evolutionarily conserved nutrient signaling and autophagy pathways.
