WebWe found that the compound-mediated cytotoxic effect against colon cancer cells was greatly improved by the concomitant inhibition of NRF2 and BiP, highlighting a critical interplay between these two molecules and their pathways that cancer cells exploit to resist to the cytotoxic effect of the anticancer therapies. 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.
