KLRG1 identifies circulating cytotoxic CD4 T cells with selective anti-tumor function in human cancer
This study identifies KLRG1 as a defining surface marker for circulating cytotoxic CD4+ T cells in melanoma patients that selectively kill MHC class II-expressing tumor cells via a granulysin-dependent mechanism while sparing antigen-presenting cells, and reveals that tumor-derived IL-6 impairs this function by driving a transition to a T follicular helper phenotype.
