Described herein are compositions and methods for treating cancer through the combination of tumor antigen-pulsed dendritic cells and Dengue Virus. The combination of the two forms of therapeutic intervention provides enhanced tumor cell reduction compared to either alone. The cancer targeted by compositions and methods described herein may be a solid cancer or blood cancer.

Described herein are compositions and methods for treating a disease, particularly a cancer, with primed dendritic cells recognizing a tumor antigen. The methods may comprise storing, shipping and/or culturing dendritic cells, where the dendritic cells are stored on a hard surface. Lysis protocols are described where the lysis does not result in complete lysis of cells in order to provide cell surface molecules maintained in a cell surface-embedded state. Non-lethal Dengue virus strains are also provided for therapeutic purposes.

Disclosed herein are methods of treating a brain cancer comprising administering to a subject in need thereof a viral composition comprising a flavivirus or portion of a flavivirus wherein the flavivirus is engineered to comprise a heterologous nucleic acid sequence encoding a suicide gene. In some embodiments, the brain cancer is selected from the group consisting of astrocytoma, oligodendroglioma, ependymoma, meningioma, schwannoma, craniopharyngioma, germinoma, and pineocytoma. In some embodiments the flavivirus comprises Zika virus, spondweni virus, kedougous virus, or a combination thereof. In some embodiments, the flavivirus comprises Zika virus. In some embodiments, the suicide gene encodes a protein that converts a prodrug into a cytotoxic agent. In some embodiments, the viral composition is administered in combination with the immunostimulatory agent.

A method of generating an artificial 3D tissue culture of a cancer grown in non-cancerous tissue, includes the steps of providing an aggregate of pluripotent stem cells or progenitor cells, culturing and expanding the cells in a 3D biocompatible matrix, wherein the cells are allowed to differentiate to develop the aggregate into a tissue culture of a desired size; wherein at least a portion of the cells are subjected to cancerogenesis by expressing a oncogene and/or by suppressing a tumor suppressor gene during any of the steps or in the tissue culture, and further including the step of allowing the cells with an expressed oncogene or suppressed tumor suppressor to develop into cancerous cells; drug screening methods; oncolytic virus screening methods; a 3D tissue culture; and a kit for performing the inventive methods.

The present invention provides compositions of CD180 targeting molecules coupled to heterologous antigens, and their use in treating and/or limiting disease.

This disclosure provides the innovation of a group of flaviviruses carrying respective lymphocyte genes that results in targeting specific T cells of immune system to therapy solid cancers and provides strategies for using these oncolytic viruses to reduce or to avoid immune resistance to single virus treatment and thus increase efficiency against cancer.

Described herein are compositions and methods for treating a disease, particularly a cancer, with a Dengue Virus and, optionally, primed dendritic cells recognizing a tumor antigen. Lysis protocols are described where the lysis does not result in complete or less than complete lysis of cells in order to provide cell surface molecules maintained in a cell surface-embedded state. Non-lethal Dengue virus strains are also provided for therapeutic purposes.
