Tumor metabolites promote tumor immune evasion. Compared with other cell types, tumor cells display increased production of immunosuppressive metabolites, such as, adenosine, R-2-HG, glutamine, and methylglyoxal in the TME. These metabolites cause cytotoxic T cell anergy, increase the infiltration of MDSCs, and impair anti-tumor immunity.
