The invention provides application of pentenedioic acid (GC) in enhancing the anti-tumor effect of T cells through metabolic reprogramming, and belongs to the technical field of biological medicine. It is found that in the tumor development process, GC is supplemented in an exogenous mode, tumor growth can be rapidly inhibited, and the anti-tumor effect depends on a TME regulation and control mechanism.

Particularly, after the CD8-resistant antibody is used for removing mouse CD8 + T cells, the anti-tumor effect of GC completely disappears, and it is confirmed that the tumor inhibition effect depends on the CD8 + T cells. Therefore, the invention proves that the lysine catabolic metabolite GC, as an immunostimulatory metabolite, can shape the immune activated TME by reactivating the functions of tumor infiltrating CD8 + T cells.
