Cytotoxicity cancer cells
WebAbstract. CD4 T cells have been implicated in cancer immunity for their helper functions. Moreover, their direct cytotoxic potential has been shown in some patients with cancer. Here, by mining single-cell RNA-seq datasets, we identified CD4 T cell clusters displaying cytotoxic phenotypes in different human cancers, resembling CD8 T cell profiles. WebDec 14, 2024 · While tumor killing is ascribed to CD8 + T cell function, pre-clinical and clinical studies have identified intra-tumoral CD4 + T cells that possess cytotoxic …
