Membrane fusion mutants of Semliki Forest virus
Previous reports have indicated that the entry of Semliki Forest virus (SFV) into cells depends on a membrane fusion reaction catalyzed by the viral spike glycoproteins and triggered by the low pH prevailing in the endosomal compartment. In this study the in vitro pH-dependent fusion of SFV with nuclease-filled liposomes has been used to select for a new class of virus mutants that have a pH-co...
متن کاملStructure of Semliki Forest virus core protein.
Alphaviruses are enveloped, insect-borne viruses, which contains a positive-sense RNA genome. The protein capsid is surrounded by a lipid membrane, which is penetrated by glycoprotein spikes. The structure of the Sindbis virus (SINV) (the type virus) core protein (SCP) was previously determined and found to have a chymotrypsin-like structure. SCP is a serine proteinase which cleaves itself from...
متن کاملPathogenesis of Semliki Forest virus encephalitis.
This article provides a review of the pathogenesis of Semliki Forest virus (SFV) encephalitis. In mice, outcome of infection varies according to age of the mouse and strain of the virus and can include acute encephalitis, subacute demyelinating meningoencephalomyelitis, and persistent subclinical central nervous system (CNS) infection. All strains of virus are virulent in mice infected <12 days...
متن کاملReconstitution of Semliki forest virus membrane
The spike glycoproteins of the Semliki forest virus membrane have been incorporated into vesicular phospholipid bilayers by a detergent-dialysis method. The detergent used was beta-D-octylglucoside which is nonionic and has an exceptionally high critical micellar concentration which facilitates rapid removal by dialysis. The vesicles obtained were of varying sizes and had spikes on their surfac...
متن کاملEnhancement of Antitumor Immunity Using a DNA-Based Replicon Vaccine Derived from Semliki Forest Virus
A DNA-based replicon vaccine derived from Semliki Forest virus, PSVK-shFcG-GM/B7.1 (Fig. 1a) was designed for tumor immunotherapy as previously constructed. The expression of the fusion tumor antigen (survivin and hCGβ-CTP37) and adjuvant molecular protein (Granulocyte-Macrophage Colony-Stimulating Factor/ GM-CSF/B7.1) genes was confirmed by Immunofluorescence assay in vitro, and immunohistoche...
