A monoclonal antibody (MCI20.6) which inhibited measles virus (MV) binding to host cells was previously used to characterize a 57- to 67-kDa cell surface glycoprotein as a potential MV receptor. In the present work, this glycoprotein (gp57/67) was immunopurified, and N-terminal amino acid sequencing identified it as human membrane cofactor protein (CD46), a(More)
The sequences of a region of the nucleocapsid protein gene, between nucleotides 1231 and 1686, encoding the C-terminal 151 amino acid residues of the nucleocapsid protein have been determined for 16 strains of measles virus. Analysis of this region showed that it is highly divergent (up to 7.2% divergence in the nucleotide sequence and 10.6% divergence in(More)
Nipah virus, a member of the paramyxovirus family, was first isolated and identified in 1999 when the virus crossed the species barrier from fruit bats to pigs and then infected humans, inducing an encephalitis with up to 40% mortality. At present there is no prophylaxis for Nipah virus. We investigated the possibility of vaccination and passive transfer of(More)
During 2005-2006, nine measles virus (MV) genotypes were identified throughout the World Health Organization European Region. All major epidemics were associated with genotypes D4, D6, and B3. Other genotypes (B2, D5, D8, D9, G2, and H1) were only found in limited numbers of cases after importation from other continents. The genetic diversity of endemic D6(More)
We infected squirrel monkeys (Saimiri sciureus) with Nipah virus to determine the monkeys' suitability for use as primate models in preclinical testing of preventive and therapeutic treatments. Infection of squirrel monkeys through intravenous injection was followed by high death rates associated with acute neurologic and respiratory illness and viral RNA(More)
Measles virus (MV) has a very limited host range, humans being the only natural reservoir of the virus. This restriction may be due to the absence of an MV receptor on the surface of non-primate cells. We have studied the MV-binding ability of several cell lines and attempted to characterize the receptor by studying the binding of 35S-labelled MV and by a(More)
Nipah virus (NiV) P gene encodes P protein and three accessory proteins (V, C and W). It has been reported that all four P gene products have IFN antagonist activity when the proteins were transiently expressed. However, the role of those accessory proteins in natural infection with NiV remains unknown. We generated recombinant NiVs lacking V, C or W(More)
A measles virus (Hallé strain) cDNA library was prepared by cloning virus-induced mRNA directly into the expression vector PCD. Clones corresponding to the measles virus haemagglutinin (HA) gene were isolated and one, PCD-HA-15, which corresponded to the complete mRNA sequence, was further characterized. After transfection into COS-7 cells, measles virus HA(More)
Measles virus genes encoding the haemagglutinin (HA), fusion protein (F) or nucleoprotein (NP) have been inserted into the vaccinia virus genome either alone or in various combinations. In each case the measles virus genes were expressed from the 7.5K promoter and were incorporated into the thymidine kinase (tk) or K1L loci of the Copenhagen strain of(More)
