1Department of Hepatobiliary and Pancreatic Surgery, State Key Laboratory of Metabolism and Regulation in Complex Organisms, Medical Research Institute, Frontier Science Center for Immunology and Metabolism, Zhongnan Hospital of Wuhan University, Wuhan University, Wuhan, Hubei, ChinaThe limited success of current immunotherapies emphasizes the need for new targets and combination treatments. V-domain Ig suppressor of T cell activation (VISTA) is a promising immune checkpoint target in cancer immunotherapy, but its regulatory mechanism is poorly understood. Through CRISPR knockout screening and proteomic analysis, we identify tripartite motif containing 25 (TRIM25) as a positive regulator for VISTA largely through antagonizing its degradation signaling. Moreover, ERK-mediated phosphorylation of VISTA at Thr284 enhances its interaction with TRIM25, leading to VISTA stabilization. A VISTA-derived phospho-peptide competitively disrupts TRIM25–VISTA interaction, thereby reducing VISTA expression and potentiating the anti-tumor efficacy of PD-1/PD-L1 blockade. Moreover, single-cell RNA sequencing analysis shows that tumor-infiltrating cytotoxic CD8+ T cells are increased in mice with T cell-specific knockout of Trim25. Of note, genetic ablation of Trim25 in T cells not only improves anti-PD-L1 immunotherapy, but also significantly ameliorates CAR T anti-tumor activity in various mouse tumor models. Collectively, this study unveils a mechanism for VISTA regulation in T cells and highlights targeting TRIM25–VISTA as a potential strategy to enhance tumor immunotherapy.
