Protection of hamsters against experimental mumps virus (MuV) infection by antibodies raised against the MuV surface glycoproteins expressed from recombinant vaccinia virus vectors.

چکیده
The fusion (F) and haemagglutinin-neuraminidase (HN) glycoproteins of mumps virus (MuV) have been produced in CV1 cells via vaccinia virus recombinants. Recombinant proteins accumulated in infected cells and were glycosylated. Upon reduction, the F protein product was completely converted into its subunits. Hamsters infected with vaccinia recombinants expressing either the F or HN proteins produced antibodies recognizing MuV antigens and neutralizing MuV infectivity in vitro. These antibodies provided protection against MuV-induced encephalitis in newborn hamsters.

Molecular differences between two Jeryl Lynn mumps virus vaccine component strains, JL5 and JL2
The Jeryl Lynn (JL) vaccine against mumps virus (MuV) contains two components, MuV(JL5) and MuV(JL2), which differ by over 400 nt. Due to the occurrence of bias in the direction of mutation, these differences and those found in nucleotide sequences of different isolates of the minor component in the vaccine (MuV(JL2)) might be due to the effect of ADAR-like deaminases on MuV grown in tissue-cul...
متن کاملFunction of small hydrophobic proteins of paramyxovirus.
Mumps virus (MuV), a rubulavirus of the paramyxovirus family, causes acute infections in humans. MuV has seven genes including a small hydrophobic (SH) gene, which encodes a type I membrane protein of 57 amino acid residues. The function of the SH protein is not clear, although its expression is not necessary for growth of MuV in tissue culture cells. It is speculated that MuV SH plays a role i...
متن کاملMouse Testicular Cell Type-Specific Antiviral Response against Mumps Virus Replication
Mumps virus (MuV) infection has high tropism to the testis and usually leads to orchitis, an etiological factor in male infertility. However, MuV replication in testicular cells and the cellular antiviral responses against MuV are not fully understood. The present study showed that MuV infected the majority of testicular cells, including Leydig cells (LC), testicular macrophages, Sertoli cells ...
متن کاملCross-Neutralization between Human and African Bat Mumps Viruses
Recently, a new paramyxovirus closely related to human mumps virus (MuV) was detected in bats. We generated recombinant MuVs carrying either or both of the fusion and hemagglutinin-neuraminidase bat virus glycoproteins. These viruses showed replication kinetics similar to human MuV in cultured cells and were neutralized efficiently by serum from healthy humans.

UNLABELLED Mumps virus (MuV), a paramyxovirus containing a negative-sense nonsegmented RNA genome, is a human pathogen that causes an acute infection with symptoms ranging from parotitis to mild meningitis and severe encephalitis. Vaccination against mumps virus has been effective in reducing mumps cases. However, recently large outbreaks have occurred in vaccinated populations. There is no ant...
