Abstract:
Monoclonal antibodies to IFN-β2/IL-6 and hybridomas producing them and production and purification of glycosylated and unglycosylated IFN-β2/ IL-6 are disclosed. The protein is useful in the treatment of breast cancer, leukemia, infectious diseases and bone marrow progenitor cell disorders.
Abstract:
Interferon y is produced in highly purified form (activity exceeding 10 8 units/ml-day) by CHO cells cotransformed by a first plasmid bearing the genomic human interferon gene under the control of the SV40 early promoter, and a second plasmid bearing a DHFR gene under similar control. Methotrexate selection yielded a clone which was a particularly efficient producer. Production of interferon y may also be facilitated by a Harvey sarcoma virus enhancer sequence.
Abstract:
Described is the use of hypericin or pseudohypericin as active therapeutic substances in the treatment of, and alleviation of symptoms of various diseases caused by viruses such as vesicular stomatitis, influenza, herpes simplex, HSV-1 and HSV-2. The mode of activity seems to be by inhibition of RNA synthesis and interfering with virus replication. Pharmaceutical compositions can be applied by a variety of routes. Topical applications have proved to be effective against a variety of viral afflictions.
Abstract:
Human interferon-beta 2A and interferon-beta 2B are produced in purified form by recombinant DNA techniques. Two separate human genes have been identified which code for the production of IFN-β 2A and IFN-β 2B , respectively. The sequence of IFN-β 2A cDNA is established. These genes and cDNA have been cloned into mammalian cells with an SV40 early promoter sequence and such genomic clones are capable of producing IFN-β 2A and IFN-β 2B . The antiviral activity of such recombinant IFN-β 2A and IFN-β 2B is demonstrated as well as other biological activity identifying them as human interferons. It has been shown that IFN-β₂ secretion is induced in human cells by growth-stimulatory cytokines.
