Virus-derived siRNA: Coronavirus and influenza virus trigger antiviral RNAi immunity in birds.
Article in Nucleic acids research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
RNA interference (RNAi) is a key antiviral immune mechanism in eukaryotes. However, antiviral RNAi in vertebrates has only been observed in cells with poor interferon systems or in viral suppressors of RNAi (VSR) deficiency virus infections. Our research discovered that infecting macrophages with wild-type coronavirus (Infectious bronchitis virus, IBV) and influenza viruses (Avian influenza virus, AIV) can trigger RNAi antiviral immunity and produce a certain amount of virus-derived siRNA (vsiRNA). These vsiRNAs have an inhibitory effect on the virus and carry out targeted silencing along the Dicer-Ago2-vsiRNA axis. Notably, these vsiRNAs are distributed throughout the virus's entire genome, with a predilection for A/U at the 5' and 3' termini of vsiRNA. In addition, Dicer cleavage produces vsiRNA based on the RWM motif, where R represents A/G, W represents A/C, and M represents A/U. We also discovered that avian LGP2 and MDA5 proteins positively impact the expression of the Dicer protein and the Dicer subtype "DicerM." Most importantly, the PS-vsiRNA plasmid combined with nanomaterial polyetherimide (PEI) showed excellent anti-virus activity in specific-pathogen-free (SPF) chickens. These findings show that RNA viruses trigger the production of the vsiRNA in avian somatic cells, which is of great significance for the application of therapeutic vaccines.
