Modified semliki forest virus expression vector that facilitates cloning.
Many commercially available systems provide a variety of strategies for high-level expression of recombinant proteins. While the prokaryotic and yeast expression systems are highly efficient and easy to use, expression systems for use in higher eukaryotic cells are still hampered by difficulties such as inefficient posttranslational processing, insufficient levels of protein production, restric...
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 کاملPlant Virus Expression Vector Development: New Perspectives
Plant made biologics have elicited much attention over recent years for their potential in assisting those in developing countries who have poor access to modern medicine. Additional applications such as the stockpiling of vaccines against pandemic infectious diseases or potential biological warfare agents are also under investigation. Plant virus expression vectors represent a technology that ...
متن کاملMembrane 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...
