Abstract
Compositions, e.g., therapeutic agents, and methods are provided for modulating gene and protein expression of Forkhead Box protein 1 (Foxp1). The therapeutic agents include short nucleic acid molecules that modulate gene and protein expression of Forkhead Box protein 1 (Foxp1) expression, viral vectors containing such molecules, T cells transduced with these viruses for adoptive therapies, and any small molecules that bind to and inactivate Foxp1. These compounds and methods have applications in cancer therapy either alone or in combination with other therapies that stimulate the endogenous immune system in the environment of the cancer, e.g., tumor.
Claims8
A composition for treating a cancer comprising a T cell pulsed ex vivo with a selected cancer-specific antigen or tumor-specific antigen, the T cell having therein a vector expressing a short hairpin RNA (shRNA) construct that down regulates or extinguishes Foxp1, the shRNA under the control of a suitable promoter, which composition is in a pharmaceutically acceptable carrier or diluent that is suitable for administration to a human subject, wherein the shRNA is expressed in the vector by a DNA sequence of SEQ ID NO:
- 5.
A composition for treating a cancer comprising a T cell pulsed ex vivo with a selected cancer-specific antigen or tumor-specific antigen, the T cell and having therein a vector expressing a short hairpin RNA (shRNA) construct that down regulates or extinguishes Foxp1, the shRNA construct under the control of a suitable promoter, which composition is in a pharmaceutically acceptable carrier or diluent that is suitable for administration to a human subject, wherein the shRNA is expressed in the vector by a DNA sequence of SEQ ID NO:
- 8, 11 or 14.
