Lassa virus (LASV), a mammarenavirus, infects an estimated 100,000–300,000 individuals yearly in western Africa and frequently causes lethal disease. Currently, no LASV-specific antivirals or vaccines are commercially available for prevention or treatment of Lassa fever, the disease caused by LASV. The development of medical countermeasure screening platforms is a crucial step to yield licensable products. Using reverse genetics, we generated a recombinant wild-type LASV (rLASV-WT) and a modified version thereof encoding a cleavable green fluorescent protein (GFP) as a reporter for rapid and quantitative detection of infection (rLASV-GFP). Both rLASV-WT and wild-type LASV exhibited similar growth kinetics in cultured cells, whereas growth of rLASV-GFP was slightly impaired. GFP reporter expression by rLASV-GFP remained stable over several serial passages in Vero cells. Using two well-characterized broad-spectrum antivirals known to inhibit LASV infection, favipiravir and ribavirin, we demonstrate that rLASV-GFP is a suitable screening tool for the identification of LASV infection inhibitors. Building on these findings, we established a rLASV-GFP-based high-throughput drug discovery screen and an rLASV-GFP-based antibody neutralization assay. Both platforms, now available as a standard tool at the IRF-Frederick (an international resource), will accelerate anti-LASV medical countermeasure discovery and reduce costs of antiviral screens in maximum containment laboratories.

To investigate the process of tubule formation for the cauliflower mosaic virus movement protein (CaMV MP), the green fluorescent protein (GFP) was fused to the MP to provide a vital marker for MP location after expression in insect cells. In contrast to the long tubular structures seen previously following baculovirus-based expression of the wild-type MP, the fusion protein produced only aggregates of fluorescing material in the cytoplasm. However, by co-expressing wild-type MP and GFP–MP, or by engineering their co-accumulation by introducing a foot-and-mouth disease virus 2A cleavage sequence between GFP and MP, long GFP-fluorescing tubules were formed. The experiments suggest that the presence of GFP at the N or C terminus of the tubule-forming domain of the CaMV MP places steric constraints upon the aggregation of the MP into a tubule but that this can be overcome by providing wild-type protein for inclusion in the aggregate.
