Establishment of Measles Virus Receptor-expressing Vero Cells Lacking Functional Poliovirus Receptors

Global efforts are underway to eliminate measles and rubella and active viral surveillance is key to achieving this goal. In addition to this, the World Health Organization announced guidelines for handling materials potentially infectious for poliovirus (PV) to minimize the risk of PV reintroduction and achieve PV eradication. To support the global efforts, we have established new PV-non-susceptible cell lines useful for the isolation of measles virus (MeV) and rubella virus (RuV) (Vero ΔPVR1/2 hSLAM+). In the cell lines, MeV and RuV replicated efficiently with no concern about PV replication.
