In addition, the prototypic arenavirus lymphocytic choriomeningitis virus (LCMV) is a superb model for the study of virus\u2013host interactions, including the basis of viral persistence and associated diseases. There is little understanding about the molecular mechanisms concerning the regulation and specific role of viral proteins in modulating arenavirus\u2013host cell interactions either associated with an acute or persistent infection, and associated disease. Here, we report the genomic and biological characterization of LCMV strains \u2018Docile\u2019 (persistent) and \u2018Aggressive\u2019 (not persistent) recovered from cloned cDNA via reverse genetics. Our results confirmed that the cloned viruses accurately recreated the<jats:italic>in vivo<\/jats:italic>phenotypes associated with the corresponding natural Docile and Aggressive viral isolates. In addition, we provide evidence that the ability of the Docile strain to persist is determined by the nature of both S and L RNA segments. Thus, our findings provide the foundation for studies aimed at gaining a detailed understanding of viral determinants of LCMV persistence in its natural host, which may aid in the development of vaccines to prevent or treat the diseases caused by arenaviruses in humans.<\/jats:p>","DOI":"10.1099\/vir.0.83464-0","type":"journal-article","created":{"date-parts":[[2008,5,12]],"date-time":"2008-05-12T15:30:09Z","timestamp":1210606209000},"page":"1421-1433","source":"Crossref","is-referenced-by-count":14,"title":["Genomic and biological characterization of aggressive and docile strains of lymphocytic choriomeningitis virus rescued from a plasmid-based reverse-genetics system"],"prefix":"10.1099","volume":"89","author":[{"given":"Minjie","family":"Chen","sequence":"first","affiliation":[{"name":"Center for Molecular Chaperones\/Radiobiology and Cancer Virology, Medical College of Georgia, Augusta, GA 30912, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shuiyun","family":"Lan","sequence":"additional","affiliation":[{"name":"Center for Molecular Chaperones\/Radiobiology and Cancer Virology, Medical College of Georgia, Augusta, GA 30912, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rong","family":"Ou","sequence":"additional","affiliation":[{"name":"Center for Molecular Chaperones\/Radiobiology and Cancer Virology, Medical College of Georgia, Augusta, GA 30912, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Graeme E.","family":"Price","sequence":"additional","affiliation":[{"name":"Center for Molecular Chaperones\/Radiobiology and Cancer Virology, Medical College of Georgia, Augusta, GA 30912, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hong","family":"Jiang","sequence":"additional","affiliation":[{"name":"Center for Molecular Chaperones\/Radiobiology and Cancer Virology, Medical College of Georgia, Augusta, GA 30912, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Juan Carlos","family":"de la Torre","sequence":"additional","affiliation":[{"name":"Molecular Integrative Neuroscience Department (MIND), The Scripps Research Institute, La Jolla, CA 92037, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Demetrius","family":"Moskophidis","sequence":"additional","affiliation":[{"name":"Center for Molecular Chaperones\/Radiobiology and Cancer Virology, Medical College of Georgia, Augusta, GA 30912, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"345","reference":[{"key":"R1","doi-asserted-by":"crossref","first-page":"11047","DOI":"10.1073\/pnas.88.24.11047","article-title":"In vitro selection of lymphocytic choriomeningitis virus escape mutants by cytotoxic T lymphocytes","volume":"88","author":"Aebischer","year":"1991","journal-title":"Proc Natl Acad Sci U S A"},{"key":"R2","doi-asserted-by":"crossref","first-page":"521","DOI":"10.1084\/jem.160.2.521","article-title":"Selection of genetic variants of lymphocytic choriomeningitis virus in spleens of persistently infected mice.
