However, it is often hindered by low primary rescue success rates or yields, especially with field-derived viral strains. APPROACH: We investigated the possibility of enhancing influenza virus rescue by eliciting cell fusion to increase the chances of having all necessary plasmids expressed within the same polykaryon. To this end we used the Maedi-Visna Virus envelope protein which has potent fusion activity in cells from a wide range of different species. RESULTS: Co-transfecting cells with the eight plasmids necessary to rescue influenza virus plus a plasmid expressing the Maedi-Visna Virus envelope protein resulted in increased rescue efficiency. In addition, partial complements of the 8-plasmid rescue system could be transfected into two separate populations of cells, which upon fusion led to live virus rescue. CONCLUSION: The simple modification described here has the potential to improve the efficiency of the virus rescue process and expand the potential applications for reverse genetic studies.","is_dataset_classified":null,"base_score":1.0986122886681096,"endowment":1.0986122886681096,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"23009349","pmcid":"PMC3558383","openalex_id":"https://openalex.org/W2014567527","authors":[],"funders":[{"funder_name":"Medical Research Council","grant_id":"MC_G0902096","title":null},{"funder_name":"Biotechnology and Biological Sciences Research Council","grant_id":"BB/H014306/1","title":"Epidemiological and evolutionary investigations of pandemic H1N1 influenza virus in pigs and associated occupational risks"},{"funder_name":"Biotechnology and Biological Sciences Research Council","grant_id":"BB/G00479X/1","title":"Transgenic approaches to generate influenza virus resistant poultry."}],"total_grants":3,"fwci":0.1942,"citation_percentile":0.56775804,"influential_citations":0,"citation_trend":[{"year":2014,"count":1},{"year":2017,"count":1}],"oa_status":"gold","license":"cc-by","oa_locations":[{"url":"https://bmcbiotechnol.biomedcentral.com/counter/pdf/10.1186/1472-6750-12-69","host_type":"journal"},{"url":"https://bmcbiotechnol.biomedcentral.com/counter/pdf/10.1186/1472-6750-12-69","host_type":"publisher"},{"url":"http://link.springer.com/content/pdf/10.1186/1472-6750-12-69.pdf","host_type":"publisher"},{"url":"http://link.springer.com/article/10.1186/1472-6750-12-69/fulltext.html","host_type":"publisher"},{"url":"https://doi.org/10.1186/1472-6750-12-69","host_type":"journal"},{"url":"https://pubmed.ncbi.nlm.nih.gov/23009349","host_type":"repository"},{"url":"https://hal.inrae.fr/hal-02646269","host_type":"repository"},{"url":"https://doaj.org/article/230150e09113494887a4822992017d4a","host_type":"repository"},{"url":"https://www.ncbi.nlm.nih.gov/pmc/articles/3558383","host_type":"repository"},{"url":"https://europepmc.org/articles/PMC3558383","host_type":"Europe_PMC"},{"url":"https://europepmc.org/articles/PMC3558383?pdf=render","host_type":"Europe_PMC"},{"url":"https://bmcbiotechnol.biomedcentral.com/track/pdf/10.1186/1472-6750-12-69","host_type":""},{"url":"http://dx.doi.org/10.1186/1472-6750-12-69","host_type":""},{"url":"https://dx.doi.org/10.1186/1472-6750-12-69","host_type":""}],"fields_of_study":["Influenza Virus Research Studies","Virus-based gene therapy research","Viral Infectious Diseases and Gene Expression in Insects","0301 basic medicine","0303 health sciences","03 medical and health sciences"],"mesh_terms":["Cloning, Molecular","Humans","Orthomyxoviridae","Influenza A virus","Plasmids","RNA, Viral","Transfection","Viral Envelope Proteins","Visna-maedi virus","HEK293 Cells"],"keywords":["Virus","Plasmid","Virology","Biology","Influenza A virus","Reverse genetics","Transfection","Viral envelope","Gene","Genetics","Mutant","Visna-maedi virus","Methodology Article","Orthomyxoviridae","Influenza","HEK293 Cells","Viral Envelope Proteins","Humans","RNA, Viral","Virus rescue","Cloning, Molecular","Cell fusion","TP248.13-248.65","Biotechnology","Plasmids"],"sdg_mappings":[{"sdg_number":3,"sdg_label":"3.
