‘Virological penicillin’: Plant MIR2911 directly targets influenza A viruses
In a new study, Chen-Yu Zhang’s group at Nanjing University present an extremely novel finding that a plant microRNA, MIR2911, which is enriched in honeysuckle, directly targets influenza A viruses (IAV) including H1N1, H5N1 and H7N9. Drinking of honeysuckle soup can prevent IAV infection and reduce H5N1-induced mice death.
MicroRNAs (miRNAs) are a class of 19-24 nucleotide non-coding RNAs that do not encode for proteins. MiRNAs bind to target messenger RNAs to inhibit protein translation. In previous studies, the same group has demonstrated that stable miRNAs in mammalian serum and plasma are actively secreted from tissues and cells and can serve as a novel class of biomarkers for disease and act as signaling molecules in intercellular communication. They have also reported that plant miRNAs can enter into the host blood and tissues via the route of food-intake…
