Taken together, our study highlights a pivotal role of CAFs in regulating monocyte recruitment and differentiation and demonstrated that CCR2 inhibition and ROS scavenging abrogate the CAF-MDSC axis, illuminating a potential therapeutic path to reversing the CAF-mediated immunosuppressive microenvironment.

Here we demonstrated that IL15-conditioned T cells were primed by the metabolic energy sensor AMPK to undergo diminished translation relative to effector T cells. However, we showed that IL15-conditioned T cells exhibited a remarkable capacity to enhance their protein translation in tumors, that which effector T cells were unable to duplicate. Studying the modulation of translation for applications in cancer immunotherapy revealed that direct ex vivo pharmacological inhibition of translation elongation primed robust T cell antitumor immunity. Our work elucidates that altering protein translation in CD8+ T cells can shape their antitumor capability. Copyright ©2020, American Association for Cancer Research.The success of checkpoint inhibitors in cancer treatment is associated with the infiltration of tissue-resident memory T cells (Trm). In this study, we found that about 30% of tumor infiltrating lymphocytes (TILs) in TME of gastric adenocarcinoma (GAC) were CD69+CD103+ Trm cells. Trm cells were low in patients with metastasis and the presence of Trm cells was associated with better prognosis in GAC patients. Trm cells expressed high PD-1, TIGIT, and CD39 and represented tumor-reactive TILs. Instead of utilizing g
