Description of Invention: Tumor immunotherapy is a promising approach for the treatment of cancer. However, current T cell-based immunotherapies are limited by the poor engraftment and functionality of the transferred T cells. Moreover, lymphodepleting regimens used to enhance engraftment and function of transferred tumor-reactive T cells are plagued by life-threatening side effects.
The scientists at the NIH recently discovered that the overexpression of microRNA-155 (miR-155) in tumor-reactive murine CD8+ T cells can enhance T cell proliferation and anti-tumor efficacy without lymphodepletion and exogenous cytokine administration. Consequently, using the miR155 overexpressing human CD8+ T cells could provide a safer, more effective T cell-based immunotherapy. This invention describes miR155 CD8+ T cell compositions and methods of using the miR155 CD8+ T cells to treat cancer through adoptive immunotherapy.
Applications: Use in enhanced adoptive immunotherapy to treat cancer
T cells with enhanced proliferation, survival, and function
Robust tumor response without the need of lymphodepletion and exogenous cytokine support
