Disclosed is a cell which expresses a surface marker associated with a professional antigen presenting cell, and a fusogenic membrane protein, where the cell may also express at its surface a tumor cell marker. Also disclosed is a fusion hybrid formed by the fusion of a tumor cell and a professional antigen presenting cell (APC) such that the resulting fusion hybrid expresses an APC marker, a tumor cell marker, and a fusogenic membrane glycoprotein. Also disclosed are compositions comprising the cells and fusion hybrids, and methods of making and using the hybrids.

International Classification:
A61K048/00 C12N015/86 C12N005/08
US Classification:
424/093200, 435/456000, 435/366000, 435/320100
Abstract:
This invention relates to a recombinant nucleic acid vector comprising a first expression cassette comprising a first promoter operably linked to a nucleic acid sequence encoding a syncytium-inducing polypeptide, wherein the first expression cassette is flanked on either side by a site recognized by a recombinase. The invention also includes a second expression cassette comprising a tissue-specific promoter operably linked to a nucleic acid sequence encoding a recombinase. The invention also includes cells and compositions including these expression cassettes and methods of reducing tumor volume by expression of these expression cassettes.

Gene Expression By Positive Feedback Activation Of A Cell Type-Specific Promoter

Assignee:
Mayo Foundation for Medical Education and Research - Rochester MN
International Classification:
C12N015/00 C12N015/63 C07H021/04
US Classification:
4353201, 435455, 536 241
Abstract:
A nucleic acid construct is described which provides cell type-specific expression of a therapeutic transgene. The construct utilizes a cell type-specific promoter which drives expression of the transgene. A positive feedback loop is introduced through the addition of a amplification promoter element operably linked to the therapeutic transgene and by providing, either as part of the same construct, or in a different construct, a transcription activator for activating the amplification promoter element. In one embodiment, the amplification promoter element is a heat shock response element (HSE) and the transcription activator is HSF-1. The construct enables functional targeting of a therapeutic gene while avoiding undesirable effects in non-targeted cells, by combining sufficiently high-level expression to promote a desirable therapeutic outcome with exceptional tissue specificity. A series of promoter elements, constructs, vectors, and therapeutic approaches is presented for gene therapy of tumors such as melanoma and other genetic diseases.
Materials And Methods For Treatment With Oncolytic Viruses And Modified Car T Cells
This document relates to methods and materials involved in treating cancer. For example, methods and materials for using one or more oncolytic viruses (OVs) in combination with an adoptive cell therapy (e.g., a chimeric antigen receptor T cell therapy) to alter one or more functions of a T cell and/or to enhance T cell expansion to treat cancer in a mammal (e.g., a human) are provided.

International Classification:
A61K 39/00 A61P 35/00
Abstract:
This document relates to methods and materials for treating a mammal having cancer. For example, compositions (e.g., vaccines) containing cells (e.g., tumor cells) expressing APOBEC3 which can be administered to a mammal (e.g., a human) having cancer to induce an immune response (e.g., an anti-tumor immune response) within the mammal are provided.

Experimental Vaccine Seems to Cure Prostate Cancer in Mice
"Many cancer vaccines display one, two or few antigens and, although this is successful in alerting the immune system to the cancer, the tumor eventually outsmarts the vaccine and adapts," explained the study's lead author, Richard Vile, an immunologist and professor at the Mayo Clinic in Rochester,
