• Microbiome composition modulates the lethal outcome of Drosophila A virus infection · 2026

  Résumé de la publication : Host-associated microbiomes can strongly influence viral infection outcomes, yet how minor variations in commensal bacterial composition modulate viral pathogenesis remain poorly understood. Here, we used Drosophila melanogaster to investigate how bacterial microbiome composition affects pathogenesis of enteric RNA viruses. Lactiplantibacillus plantarum supplementation…

• The microbiota affects energy production, nitrogen excretion and sterol metabolism in mosquito larvae · 2026

  Résumé de la publication : Mosquito larvae rely on a living microbiota for normal development because the microbiota supplies essential nutrients, particularly vitamins. Beyond vitamin provision, transcriptomic data suggest that the microbiota also supports other key nutritional processes. Here, we explored these roles by conducting a metabolomics…

• The circadian clock gene period regulates the composition and daily bacterial load of the gut microbiome in Drosophila melanogaster · 2025

  Résumé de la publication : While Drosophila melanogaster serves as a crucial model for investigating both the circadian clock and gut microbiome, our understanding of their relationship in this organism is still limited. Recent analyses suggested that the Drosophila gut microbiome modulates the host circadian transcriptome to…

• Limited impact of the siRNA pathway on transposable element expression in Aedes aegypti · 2025

  Résumé de la publication : Background Transposable elements (TEs) are DNA sequences that can change their position within a genome. In insects, small RNA pathways are central to the transcriptional and post-transcriptional regulation of TE expression. The Piwi-interacting RNA (piRNA) pathway is particularly important in germline tissues,…
