Master regulators of regulatory T cell tumor infiltration

This technology is a set of master regulators of tumor regulatory T cell infiltration that can be targeted for cancer treatment.

Unmet Need: Effective and specific cancer immunotherapy

Current immunopharmacological cancer treatments target receptors and cytokines that affect both peripheral and tumor infiltrating immune cells. This leads to many unintended side effects that often require patients to terminate treatment. Unfortunately, treatments that only target immune cells in the tumor environment are not available.

The Technology: Genetic targets that specifically alter regulatory T cell tumor infiltration

This technology describes a set of 17 master regulatory genes that control infiltration of tumor regulatory T cells. These genes are specifically enriched in tumor infiltrating regulatory T cells and do not affect survival of peripheral or non-regulatory T cell populations. Targeting these master regulators functionally modulates regulatory T cell infiltration and may have combinatorial or synergistic effects for enhancing anti-tumor immunity.

This technology has been validated using a CRISPR knockout screen in mice.

Applications:

• Immunotherapy for cancer treatment
• Research model for studying regulatory T cell tumor infiltration
• Treatment for autoimmune diseases
• Preventing organ transplant rejection
• Treating chronic inflammation
• Characterizing regulatory T cell function in diverse inflammatory conditions

Advantages:

• Specific to tumor infiltrating regulatory T cells
• Applicable to many tumor types
• Compatible with other immunotherapies
• May have synergistic functions that can be co-targeted
