摘要:
The present invention is directed to a method of reducing the viability of a tumor cell involving administering a virus that is not a common human pathogen to the tumor cell. Preferably, the virus exhibits differential susceptibility, in that normal cells are not affected by the virus. This differential susceptibility is more pronounced in the presence of interferon. The tumor cell is characterised by having low levels, or no PKR activity, or as being PKR-/-, STAT1-/- or both PKR-/- and STAT-/-. The virus is selected from the group consisting of Rhabdovirus and picornavirus, and preferably is vesicular stomatitis virus (VSV) or a derivative thereof.
摘要:
The present invention provides a method of increasing expression of a promoter distal gene in a virus of the order Mononegavirales, and a recombinant virus constructed by such method. Also provided is a method of attenuating a virus of the order Mononegavirales, and of constructing an attenuated virus useful for a vaccine.
摘要:
A method for treating a biological or pharmaceutical product to inactivate viruses and pyrogens therein comprising the steps of adsorbing said product onto a solid phase; treating the adsorbed product with a virus or pyrogen inactivating agent; separating the solid phase and quantitatively removing the residual inactivating agent therefrom; and recovering said product.
