Abstract

To develop a gene therapeutic method for human cytomegalovirus (HCMV), the IE86 specific short hairpin (sh) RNA expressing vector was constructed and subsequently transfected into MRC-5 cells. After infection of these cells with HCMV AD169, expression of IE86 was reduced strikingly as compared to the control. In addition, the inhibitory effect corresponded to a decrease in viral DNA replication and the virus-induced cytopathic effect. Measurement of the virus yield demonstrated that infection of cells expressing IE86-specific shRNA resulted in suppression of the formation of infectious viral progeny. These observations indicate that IE86 can be used as an effective target against HCMV infection using RNA interference (RNAi) technology, which provides new possibilities for anti-HCMV studies.
