VSV infection is sensed by Drosophila, attenuates nutrient signaling, and thereby activates antiviral autophagy

Abstract

Innate immune mechanisms are the first line of defense against pathogens including viruses. This work identifies autophagy, an innate intracellular degradative pathway, as antiviral against Vesicular Stomatitis Virus (VSV) in Drosophila. VSV is sensed by cells via the surface glycoprotein leading to the attenuation of the nutrient signaling pathway thereby activating an antiviral autophagic program. ©2009 Landes Bioscience.
