- Descripción
- Junín virus (JUNV), the etiological agent of the Argentine hemorrhagic fever, has a single-stranded RNA genome with ambisense expression which encodes for five proteins. In previous works we have demonstrated that the Z arenavirus matrix protein represents an attractive target for antiviral therapy. With the aim of studying a new alternative therapeutic mechanism, four Z-specific siRNAs (Z1- to Z4-siRNAs) were tested showing variable efficacy. The most effective inhibitor was Z2-siRNA targeted at the region encompassed by nt 179-197 of Z gene. The efficacy of this Z2-siRNA against JUNV was also demonstrated in virus-infected cells, by testing infectious virus plaque formation (92.8% JUNV yield reduction), viral RNA level or antigen expression, as well as in cells transfected with Z-specific reporter plasmids (91% reduction in expression of Z-EGFP fusion protein). Furthermore, the lack of effect of this Z-siRNA on the expression of other JUNV proteins, such as N and GPC, confirmed the specificity of action exerted by Z2-siRNA on Z transcript. Thus, the present study represents the first report of virus inhibition mediated by RNA interference for a New World arenavirus. © 2009 Elsevier B.V. All rights reserved.
