gd T cells usually infiltrate many different types of cancer, but it is unclear whether they inhibit or promote tumor progression. Moreover, properties of tumor-infiltrating gd T cells and those in the corresponding normal tissue remain largely unknown. Here we have studied features of gd T cells in colorectal cancer, normal colon tissue and peripheral blood, and correlated their levels with clinicopathologic hallmarks. Flow cytometry and transcriptome analyses showed that the tumor comprised a highly variable rate of TILs (5-90%) and 4%gd T cells on average, with the majority expressing Vd1. Most Vd1 and Vd2 T cells showed a predominant effector memory phenotype and had reduced production of IFN-g which was likely due to yet unidentified inhibitory molecules present in cancer stem cell secretome. Transcriptome analyses revealed that patients containing abundant gd T cells had significantly longer 5-year disease free survival rate, suggesting their efficacy in controlling tumor at very early stage.
