198-T Cell Immunoediting Prevents Sarcoma Tumor Emergence
This article investigates the mechanisms of T cell-mediated tumor elimination, known as immunoediting, focusing on the early stages of sarcoma development in a mouse model. The research, conducted by Cheung et al. and published in Cancer Cell, details how the presence of T cells, specifically CD4+ and CD8+ T cells, significantly reduces tumor penetrance and delays tumor emergence. Key findings reveal a dual mechanism for T cell control: an IFNγ-independent pathway eliminates neoantigen-expressing tumor cells, while an IFNγ-dependent bystander effect eliminates neighboring neoantigen-negative…
