A summary of the article is shown below:

Varicella-zoster virus (VZV) leads to chicken pox on primary infection and herpes zoster on reactivation. Recent studies suggest that microRNA2911 (MIR2911), honeysuckle (HS)-encoded atypical microRNA, has potential as a therapeutic agent against influenza and EV71 virus infections. Here, we report that MIR2911 directly inhibits VZV replication by targeting the IE62 gene. The luciferase reporter assay and bioinformatics prediction revealed that MIR2911 could target the IE62 gene of VZV. The VZV-encoded IE62 protein expression was inhibited significantly by synthetic MIR2911, while the expression of the mutants, whose MIR2911-binding sites were modified, was not inhibited. The RNA extracted from HS decoction and synthetic MIR2911 considerably suppressed VZV infection. However, it did not influence viral replication of a mutant virus with alterations in the nucleotide sequences of IE62. At the same time, the RNA extracted from HS decoction treated with the anti-MIR2911 antagomir could not inhibit the VZV replication, demonstrating that VZV replication was specifically and sufficiently inhibited by MIR2911. These results indicated that, by targeting the IE62 gene, MIR2911 may effectively inhibit VZV replication. Our results also suggest a potential novel strategy for the treatment and prevention of diseases caused by VZV infection.
