Polyprotein Processing as a Determinant for In Vitro Activity of Semliki Forest Virus Replicase
Semliki Forest virus (SFV) is an arthropod-borne alphavirus that induces membrane invaginations (spherules) in host cells. These harbor the viral replication complexes (RC) that synthesize viral RNA. Alphaviruses have four replicase or nonstructural proteins (nsPs), nsP1-4, expressed as polyprotein P1234. An early RC, which synthesizes minus-strand RNA, is formed by the polyprotein P123 and the...
متن کاملOncolytic Semliki Forest Virus Vector as a Novel Candidate
Oncolytic viruses are a promising tool for treatment of cancer. We studied an oncolytic Semliki Forest virus (SFV) vector, VA7, carrying the enhanced green fluorescent protein gene (EGFP), as a novel virotherapy candidate against unresectable osteosarcoma. The efficiency and characteristics of the VA7EGFP treatment were compared with a widely studied oncolytic adenovirus, Ad5#24, both in vitro ...
متن کاملIdentification of linear epitopes on Semliki Forest virus E2 membrane protein and their effectiveness as a synthetic peptide vaccine.
Semliki Forest virus (SFV) infection of mice was used as a model to study the applicability of synthetic peptides containing only linear epitopes as viral vaccines. The identification of linear epitopes with vaccine potential on the E2 membrane protein of SFV was based on the binding of SFV-specific antibodies to a set of overlapping synthetic hexapeptides (Pepscan) representing the whole E2 am...
متن کاملSemliki Forest virus envelope proteins function as proton channels.
It has been shown that isolated nucleocapsids of Semliki Forest virus (SFV) contract upon low pH exposure (Soederlund et al., 1972). This contraction of the nucleocapsids has been used as an indicator to demonstrate that the spike proteins of SFV can translocate protons into the interior of the virus particle upon low pH (5.8) exposure. Spikeless virus particles obtained after bromelain digesti...
متن کاملThe E2 glycoprotein of classical swine fever virus is a virulence determinant in swine.
To identify genetic determinants of classical swine fever virus (CSFV) virulence and host range, chimeras of the highly pathogenic Brescia strain and the attenuated vaccine strain CS were constructed and evaluated for viral virulence in swine. Upon initial screening, only chimeras 138.8v and 337.14v, the only chimeras containing the E2 glycoprotein of CS, were attenuated in swine despite exhibi...
