Why do males and females differ in infection outcomes? In our study just published in #GENETICS
@GeneticsGSA using #Drosophila melanogaster, we show that #sexdifferences in nutritional #immunity —shape resistance to #infection by Providencia. https://t.co/J5zzyetHEF

New preprint alert! Here, we showed that microbiota shapes infection outcome in Drosophila by modulating host metabolism and immunity.

Virome regulates nutrient sensing

Enteric virome, dominated by bacteriophages, can autonomously activate host immune signaling to modulate intestinal metabolic responses and regulate carbohydrate digestion & absorption
