Sex Differences in Drosophila Intestinal Metabolism Contribute to Sexually Dimorphic Infection Outcome and Alter Gut Pathogen Virulence

Marko Rubinić, Yi Yu, Aranzazu Arias-Rojas…·Igor Iatsenko

This study shows sex differences in Drosophila intestinal metabolism affect infection outcomes, with males clearing pathogens via antioxidant pathways while females experience higher pathogen virulence.

Infection-Induced Elevation of Gut Glycosaminoglycans Fosters Microbiota Expansion in Drosophila melanogaster

Aranzazu Arias-Rojas, Marko Rubinić, Jasmin Albiez…·Igor Iatsenko

This study identifies host genetic variants linked to Lactiplantibacillus plantarum abundance in Drosophila melanogaster and shows heparan sulfate synthesis promotes microbiota expansion and intestinal defense during infection.
