2004 MAR 3 - (NewsRx.com & NewsRx.net) -- The cucumber mosaic virus can be used as a carrier of a hepatitis C virus-derived epitope.
"Cucumber mosaic virus (CMV) is a three component isodiametric plant virus which is common worldwide and has an extremely wide host range. A pseudorecombinant was made, derived from the RNA3 component of the CMV-S strain, carrying the coat protein (CP) gene, and the RNA1,2 components of the CMV-D strain. This system developed mild mosaic and vein clearing in Xanthi tobacco three weeks after inoculation," scientists in Italy report.
"The CP gene was then engineered in three different positions, to encode a hepatitis C virus (HCV) epitope," said A. Natilla and collaborators at the Universita Degli Studi della Basilicata and Universita Degli Studi di Bari. "The selected peptide was the so-called R9 mimotope, a synthetic surrogate derived from a consensus profile of many hypervariable region 1 (HVR1) sequences of the putative HCV envelope protein E2. Serum samples from 60 patients with chronic hepatitis C displayed a significant immunoreactivity to crude plant extracts ...
