Antibody-mediated activation of sindbis virus
Virology, 1988The biological activity of an anti-Sindbis monoclonal antibody (MCAB 49) has been explored. The antibody recognizes an epitope on the E2 glycoprotein of Sindbis virus and, in the presence of complement (C'), neutralizes virus infectivity. In the absence of C', reaction of the antibody with our laboratory strain of Sindbis, SB, increased the number of ...

Template Activity of Parainfluenza Virus Ribonucleoprotein
Nature, 1970WE have shown previously that Sendai virus ribonucleoprotein (RNP) particles in the cytoplasm of infected cells are associated with ribosomes in complexes of buoyant density δ = 1.45 g cm−3, and that these take up labelled amino-acids1,2. We now demonstrate that Sendai virus RNP stimulates the incorporation of labelled amino-acids into polypeptides in ...

Anti-influenza virus activity of biflavonoids
Bioorganic & Medicinal Chemistry Letters, 2007Ginkgetin was found to inhibit the influenza virus sialidase. Ginkgetin-sialic acid conjugates showed a significant survival effect in the influenza-virus-infected mice.

Activation of latent virus infection by heat
Virology, 1963Abstract The bean plant Phaseolus vulgaris L. var. Pinto, although normally immune to the mild strain of tobacco mosaic virus (TMV) U2, can be made susceptible to infection by subjecting primary leaves, previously inoculated with virus, to a sublethal heat treatment.

Heat activation of plant virus infections
Virology, 1961Abstract When bean or cowpea leaves were inoculated with certain viruses and, within 8 seconds after mechanical inoculation, held in water or mercury for 0.5-4 seconds at 45–65°, the number of resulting lesions were increased. As the interval from inoculation to heating was increased beyond 10 seconds, heat activation decreased and heat inactivation ...

Biological Activity of Tumor Virus Dna
1977Publisher Summary This chapter deals with recent studies on the biological activity of viral DNA, with emphasis on the studies dealing with cell transformation. It describes commonly used techniques for assaying biological activity of purified viral DNA and discusses the development of these assays and their mechanism of action.

Virus Entry and Innate Immune Activation
2008Human cytomegalovirus (HCMV) exhibits an exceptionally broad cellular tropism as it is capable of infecting most major organ systems and cell types. Definitive proof of an essential role for a cellular molecule that serves as an entry receptor has proven very challenging.

Activity of Herpetic Virus in Mice
Journal of Infectious Diseases, 1929Investigation concerning the nature and activity of the filtrable viruses is limited for the most part to animal experimentation until their cultivation without the body is a practical accomplishment. This limitation is increased further by the host specificity of some of the viruses.

Powassan virus: persistence of virus activity during 1966.
Canadian Medical Association journal, 1967Powassan virus isolations were achieved from three of 60 pools of Ixodes cookei ticks removed from 286 groundhogs (Marmota monax) which were collected some 200 miles north of Toronto between May 5 and September 5, 1966. Virus yields per pool of one to 11 ticks ranged from 10(2.5) to 10(6.0) TCD(50) for primary swine kidney tissue cultures, and positive
