  • Patent number: 11613750
    Abstract: Methods of reducing levels of virus molecules and/or treating viral infections include contacting cells with an oligonucleotide inhibitor that targets a cellular host factor that is a target RNA or target protein involved in viral replication. A pharmaceutical composition can include such an oligonucleotide inhibitor in an amount effective for treating an infection, such as a hepatitis B infection or a respiratory virus infection, such as a coronavirus infection.
