The tumor microenvironment (TME) is a complex system containing multiple cell types and cytokines that control cancer cell growth and promote cancer immune evasion.
· Developing drugs to treat other brain tumors and other types of cancer.
TIGIT and PD-1 Immune Checkpoint Pathways Are Associated With Patient Outcome and Anti-Tumor Immunity in Glioblastoma.
When applied to immune cells, this enzyme inhibitor enhanced dendritic proliferation and drove T cell differentiation away from immunosuppressive regulatory T cells and towards cytotoxic T cells.
· Induces anticancer immune response.
This novel enzyme inhibitor is a promising immunotherapy target that promotes antitumor immune response and increases tumor control when used with a tumor vaccine.
One type of immunotherapy at the forefront of the field is the use of chimeric antigen receptor (CAR) T cells to genetically redirect T cells to tumor targets.
Using virally-mediated genetic reprogramming may be key to creating metabolically robust CAR T cells for use in solid tumor immunotherapy.
To reap the benefits that this treatment has yielded for hematologic malignancies, CAR T cells will need to be more metabolically durable in order to perform in the microenvironment of solid tumors.
