SiRNA Targeting the 2Apro Genomic Region Prevents Enterovirus 71 Replication In Vitro.

ABSTRACT: Enterovirus 71 (EV71) is the most important etiological agent of hand, foot, and mouth disease (HFMD) in young children, which is associated with severe neurological complications and has caused significant mortalities in recent HFMD outbreaks in Asia. However, there is no effective antiviral therapy against EV71. In this study, RNA interference (RNAi) was used as an antiviral strategy to inhibit EV71 replication. Three small interfering RNAs (siRNAs) targeting the 2Apro region of the EV71 genome were designed and synthesized. All the siRNAs were transfected individually into rhabdomyosarcoma (RD) cells, which were then infected with strain EV71-2006-52-9. The cytopathic effects (CPEs) in the infected RD cells, cell viability, viral titer, and viral RNA and protein expression were examined
