Arbovirus-derived piRNAs exhibit a ping-pong signature in mosquito cells.
The siRNA pathway is an essential antiviral mechanism in insects.Whether other RNA interference pathways are involved Concentrators in antiviral defense remains unclear.Here, we report in cells derived from the two main vectors for arboviruses, Aedes albopictus and Aedes aegypti, the production of viral small RNAs that exhibit the hallmarks of ping
