In this study, we demonstrated that the expression of PD-L1 is regulated by METTL3. We found that METTL3 mediated N6-methyladenosine (m6A) modification of PDL1 mRNA in the 3' untranslated region and induced mRNA degradation through an m6A/YTHDF2-dependent pathway in human gastric cancer cells. METTL3 knockdown or inhibition in gastric cancer cells significantly enhanced Jurkat cell migration and cytotoxic activity.

In this study, we examine the impact of NEDDylation in CD8+ T cell-mediated antitumor responses. Analysis of publicly available single-cell RNA sequencing databases revealed that CD8+ tumor-infiltrating lymphocytes showed increased expression of NEDD8 during their differentiation into effector memory cells. In vitro activation of mouse and human CD8+ T cells drove the upregulation of the NEDDylation enzymatic pathway, resulting in an enrichment of NEDDylated proteins. In vivo tumor challenge assays demonstrated that CD8+ T cells lacking NAE1 exhibited reduced antitumor capability and a less activated phenotype with compromised differentiation into effector cells. Upregulating NEDDylation by knocking out deNEDDylase sentrin-specific protease 8 increased the in vitro cytotoxic capability of CD8+ CAR T cells. In addition, LC MS/MS proteomic analyses of NAE1-deficient CD8+ T cells and CD8+ T cells treated with the NEDDylation inhibitor MLN4924 showed a pronounced impairment in metabolic pathways, including glycolysis and oxidative phosphorylation. In this context, we validated lactate dehydrogenase A, α-enolase, and hexokinase 1, which are relevant glycolytic enzymes, as NEDD8 targets.

Immunophenotyping of PBMC demonstrated increased activation and differentiation of T cells and higher expression of exhaustion markers in irColitis compared with UC. In contrast, dendritic cells and B cells demonstrated increased markers of activation in patients with UC.
