KRAS mutations are associated with an immunosuppressive microenvironment in patients with colorectal cancer (CRC). Here the authors show that knockout of SLC25A22, a mitochondrial glutamate carrier, reverts KRAS-mediated immunosuppression in preclinical CRC models, by suppressing CXCL1 production and impairing MDSC recruitment.
