摘要

The recombinant engineering of trisegmented lymphocytic choriomeningitis virus (LCMV) to express two genes of interest was recently reported. We used this technology to efficiently express green fluorescent protein (GFP) and the immunoregulatory gene product interleukin-10 (IL-10) in vitro, assess IL-10 function in vivo during viral meningitis, and generate specific, robust monoclonal antibody responses to IL-10. Tripartite viruses were attenuated in wild-type and TLR7−/− mice. However, IFNAR1−/− mice sustained systemic viral replication when 2 nucleotide substitutions from a persistent LCMV variant were present. These findings demonstrate the utility of tripartite LCMV in vitro and in vivo to study genes in the context of a well-defined model system.
