This work highlights that parasites 🪱 can adapt genomic fossils into tools for cross-species communication 🧬

We also found that non-autonomous copies and soloLTRs are the preferred sources of secreted exWAGO small RNA guides, suggesting that degradation is followed by co-option for cross-species RNA communication.

Using comparative transcriptomics, we demonstrated that exWAGO regulates a broad set of transposable elements, with a deep and conserved link to the modulation of LTR retrotransposons.

Comparative transcriptomics reveals an extracellular worm argonaute as an ancestral regulator of LTR retrotransposons. Safeguarding the genome from non-self elements is essential for reproduction, development, and ageing. One of the major threats to genome integrity is Transposable Elements (TEs), which can be post–tr...

#TREnD2025 virtual day is here!! First talk starting now! 🥳

Super excited to see our work shared with the scientific community! We know #Argonaute proteins can be extracellular, but can they be transferred to recipient cells and can they function? Happy reading!
