Abstract:Defective autophagy is associated with chronic inflammation. Loss-of-function of the core autophagy gene Atg16l1 increases risk for Crohn’s disease by enhancing innate immunity in macrophages. However, autophagy also mediates clearance of intracellular pathogens. These divergent observations prompted a re-evaluation of ATG16L1 in antimicrobial immunity. In this study, we found that loss of Atg16l1 in macrophages enhanced the killing of virulent Shigella flexneri (S.flexneri), an enteric bacterium that resides … Show more
