Macroautophagy was recently shown to regulate both lymphocyte biology and innate immunity. In this study we sought to determine whether a deregulation of autophagy was linked to the development of autoimmunity. Genome-wide association studies have pointed out nucleotide polymorphisms that can be associated with systemic lupus erythematosus, but the(More)
Macroautophagy often abbreviated by "autophagy" is an intracellular degradation mechanism linked to lysosomal activity. Autophagy is conserved from yeast to mammals and plays a role in the response to energetic stress and in organelle homeostasis. Autophagy is also involved in the regulation of immunity, in particular in the adaptive immune response, which(More)
UNLABELLED Antiviral immunity in the model organism Drosophila melanogaster involves the broadly active intrinsic mechanism of RNA interference (RNAi) and virus-specific inducible responses. Here, using a panel of six viruses, we investigated the role of hemocytes and autophagy in the control of viral infections. Injection of latex beads to saturate(More)
