Provided are modified cells and cell lines containing extracellular enveloped viruses (EEV), methods of producing serum-resistant EEVs, and programmed EEVs for systemic oncolytic viral therapy. The viruses are high EEV producing viruses that contain genome modifications that alter properties and / or activities of the viruses. The cells and cell lines are modified to encode polypeptides or peptides that are displayed on their membranes, which, when virus is propagated in the cells, encases the virus so that the polypeptides and peptides from the cell membrane are displayed on the virus. The viruses, thus contain modified outer envelopes that display polypeptides and / or peptides encoded by the virus and from the cell membranes. This combination provides viruses whose properties and activities can be programmed by virtue of the cells in which they are produced and viral genome modifications. The viruses can be used for treating cancers or, because the properties of the virus, including tropisms, other diseases, disorders, and conditions involving targeted cells.

Also provided herein are recombinant oncolytic virus strains that include an inactivating mutation in one or more viral genes, and / or one of more heterologous nucleic acids each encoding one or more heterologous gene products. The viruses, e.g., vaccinia viruses, provided herein, including recombinant vaccinia viruses, can be used as an oncolytic virus therapy, e.g., an oncolytic vaccinia virus therapy, for treating cancer. Also provided herein are pharmaceutical compositions and methods and uses of the viruses, e.g., vaccinia viruses, for treating cancer, as well as nucleic acids encoding the viruses.

The present invention provides compositions and methods for treating HPV infections, including pre-malignant and cancerous infections. Compounds that specifically bind to and inactivate the HPV E6 protein are disclosed.

MEF2C haploinsufficiency syndrome (MCHS) is a neurodevelopmental disorder with profound impacts on the affected children and their families. Deletion or mutation of one copy of a MEF2C gene, which codes for an activity-regulated transcription factor, causes MEF2C Haploinsufficiency syndrome. Described herein are nucleic acid molecules comprising an expression cassette comprising a MEF2C isoform coding sequence and a neuronal specific promoter that is operably linked to the MEF2C isoform coding sequence. Recombinant adeno-associated virus vectors comprising the nucleic acid molecules, and self-complementary forms of adeno-associated virus vectors comprising the nucleic acid molecules. Also provided are pharmaceutical compositions for treating MEF2C haploinsufficiency syndrome, methods of treating MEF2C haploinsufficiency syndrome in a patient in need thereof, and methods of inducing transgenic expression of MEF2C in a subject.

Provided herein are clonal strains of a vaccinia virus that exhibits enhanced anti-tumor properties and / or reduced immunogenicity, and recombinant vaccinia virus derived from the same. Also provided herein are recombinant oncolytic virus strains that include an inactivating mutation in one or more viral genes, and / or one of more heterologous nucleic acids each encoding one or more heterologous gene products. The viruses, e.g., vaccinia viruses, provided herein, including recombinant vaccinia viruses, can be used as an oncolytic virus therapy, e.g., an oncolytic vaccinia virus therapy, for treating cancer. Also provided herein are pharmaceutical compositions and methods and uses of the viruses, e.g., vaccinia viruses, for treating cancer, as well as nucleic acids encoding the viruses.

The invention relates to the technical field of biology, and discloses an anti-flavivirus protein or polypeptide and application thereof. The antiviral protein or polypeptide provided by the invention can inhibit flavivirus replication and activity, achieves the purpose of resisting flavivirus infection or preventing flavivirus infection, and has the potential of being used as an anti-flavivirus drug. As no medicine for effectively treating flavivirus infection exists at present, the antiviral protein or polypeptide provided by the invention has a wide application prospect due to good resistance to flavivirus under the condition of lack of an appropriate antiviral therapy.
