Genetically modified immune cells increase potency of adoptive immunotherapy
The potency of cancer immunotherapies for solid tumors are often diminished by inadequate metabolic reprogramming and resulting immune evasion in cancer. To acquire a fully activated state upon antigen encounter, T cells must undergo metabolic reprogramming to support cell growth, proliferation, and cytotoxic function. This reprogramming is sensitive to regulation of nutrient transporters and nutrient availability. Unfortunately, the tumor microenvironment in cancer is associated with limited nutrients due to competition between the tumor cells and infiltrating immune cells.
The Mackall lab invented a method to metabolically enhance immune cells during immunotherapy. Through the regulation of a group of genes, the invention leads to enhanced metabolic reprogramming and subsequently increases immune cell activation, cytokine secretion and tumor killing. The invention also functionally restores exhausted T cells and can be applied to immune cells expressing natural receptors, or those engineered to express antigen specific receptors such as chimeric antigen receptors (CARs) and recombinant TCRs.
