  • Title: Manipulation of the Semliki Forest virus genome and its potential for vaccine construction.
    Author: Atkins GJ, Sheahan BJ, Liljeström P.
    Journal: Mol Biotechnol; 1996 Feb; 5(1):33-8. PubMed ID: 8853014.
    Abstract:
    The Semliki Forest virus (SFV) expression vector consists of a plasmid based on the SFV infectious clone. Foreign genes may be inserted into the structural coding region, transcribed as RNA, and expressed in cell culture after transfection. RNA containing inserted sequences may be packaged into virions using a helper systems. This allows efficient infection and expression without chemical transfection, but only one round of multiplication is possible. The biosafety of the system has been increased by the introduction of multiple mutations, specifying a maturation defect, into the helper. Potential vaccines can be constructed by insertion of genes coding for antigenic proteins into the vector. Following insertion of the influenza virus nucleoprotein (NP) into the SFV vector, immunity was induced following injection of packaged or naked RNA into mice. The SFV vector is a "suicide" expression vector that has great potential for the construction of vaccines for both human and veterinary use.
