- W3022853429 abstract "ABSTRACT γδ T cells are a distinct subgroup of T cells that bridge the innate and adaptive immune systems and can attack cancer or virus-infected cells in an MHC-unrestricted manner. Despite its antitumor ability in both autologous and allogeneic settings, earlier trials of adoptive γδ T cell transfer in solid tumors had limited success due to limitations in cell expansion and the lack of a strategy to modulate tumor lytic interactions between γδ T and cancer cells. Here, we show through quantitative surface proteomics and gene enrichment analyses that DNA methyltransferase inhibitors (DNMTis) upregulate multiple surface molecules related to γδ T cell activation in cancer cells. DNMTi treatment of human lung cancer potentiates tumor lysis by ex vivo -expanded γδ T cells using a clinical-grade expansion protocol developed by our team to enrich for the Vδ1 subset while preserving their antitumor effector functions. Mechanistically, DNMTis enhance immune synapse formation and stabilize the synaptic cleft to facilitate γδ T-mediated tumor lysis. Through integrated analysis of RNA-seq, DNA methylation, and ATAC-seq, we demonstrate that depletion of DNMTs induces coordinated pattern alterations of immune synaptic-cytoskeletal networks at the cancer side of the immune synapse. In addition, single-cell mass cytometry reveals enrichment of polyfunctional γδ T subsets by DNMTis. Combined DNMTi and adoptive γδ T transfer in a mouse lung cancer model offers a significant survival benefit. Consistently, the DNMTi-associated cytoskeleton signature identifies a subset of lung cancer patients with improved survival. Our results demonstrate that epigenetic mechanisms are crucial for cytoskeletal remodeling in cancer to potentiate immune attack and support a combinatorial strategy of DNMTis and γδ T cell-based immunotherapy in lung cancer management. One Sentence Summary DNA methyltransferase inhibitors potentiate the killing of lung cancer by γδ T cells through remodeling cytoskeletal-immune synaptic networks." @default.
