  • Title: Epitope presentation system based on cucumber mosaic virus coat protein expressed from a potato virus X-based vector.
    Author: Natilla A, Hammond RW, Nemchinov LG.
    Journal: Arch Virol; 2006 Jul; 151(7):1373-86. PubMed ID: 16489509.
    Abstract:
    The Cucumber mosaic virus Ixora isolate (CMV) coat protein gene (CP) was placed under the transcriptional control of the duplicated subgenomic CP promoter of a Potato virus X (PVX)-based vector. In vitro RNA transcripts were inoculated onto Nicotiana benthamiana plants and recombinant CMV capsid proteins were identified on Western blots probed with CMV antibodies 5-7 days post-inoculation. PVX-produced CMV CP subunits were capable of assembling into virus-like particles (VLPs), which were visualized by electron microscopy. We further used the PVX/CMVCP system for transient expression of recombinant CMV CP constructs containing different neutralizing epitopes of Newcastle disease virus (NDV) engineered into the internal betaH-betaI (motif 5) loop. Both crude plant extracts and purified VLPs were immunoreactive with CMV antibodies as well as with epitope-specific antibodies to NDV, thus confirming the surface display of the engineered NDV epitope. Our study demonstrates the potential of PVX/CMVCP as an expression tool and as a presentation system for promising epitopes.
