Centrifuge Experiments with the Virus of Vaccinia
Centrifuge experiments have been carried out with cell-free, active filtrates of vaccinia virus. The experiments have shown that the virus can be concentrated by this method, even in filtrates which have been subjected to prolonged preliminary centrifugation to throw down any inert particles which may have been present in the original filtrate. This fact, together with the knowledge that the vi...
متن کاملMajor neutralizing sites on vaccinia virus glycoprotein B5 are exposed differently on variola virus ortholog B6.
Immunization against smallpox (variola virus) with Dryvax, a live vaccinia virus (VV), was effective, but now safety is a major concern. To overcome this issue, subunit vaccines composed of VV envelope proteins from both forms of infectious virions, including the extracellular enveloped virion (EV) protein B5, are being developed. However, since B5 has 23 amino acid differences compared with it...
متن کاملCharacterization of chimpanzee/human monoclonal antibodies to vaccinia virus A33 glycoprotein and its variola virus homolog in vitro and in a vaccinia virus mouse protection model.
Three distinct chimpanzee Fabs against the A33 envelope glycoprotein of vaccinia virus were isolated and converted into complete monoclonal antibodies (MAbs) with human gamma 1 heavy-chain constant regions. The three MAbs (6C, 12C, and 12F) displayed high binding affinities to A33 (K(d) of 0.14 nM to 20 nM) and may recognize the same epitope, which was determined to be conformational and locate...
متن کاملThermal inactivation studies with variola virus.
In recent years, considerable interest has been manifested in the thermal inactivation of animal viruses (Friedman and De Berry, 1959; LehmannGrube and Syverton, 1959; Youngner, 1957; Woese, 1960). Apart from the practical aspects, studies of the temperature sensitivity of virus particles offer a natural step in the analysis of their physicochemical properties (Gard and Maal0e, 1959) and, as su...
متن کاملProtection against lethal vaccinia virus challenge in HLA-A2 transgenic mice by immunization with a single CD8+ T-cell peptide epitope of vaccinia and variola viruses.
CD8(+) T lymphocytes have been shown to be involved in controlling poxvirus infection, but no protective cytotoxic T-lymphocyte (CTL) epitopes are defined for variola virus, the causative agent of smallpox, or for vaccinia virus. Of several peptides in vaccinia virus predicted to bind HLA-A2.1, three, VETFsm(498-506), A26L(6-14), and HRP2(74-82), were found to bind HLA-A2.1. Splenocytes from HL...
