We found that while γδ27+ cells do not produce IL‐17, even under strong type 17‐driving conditions, γδ27− T cells can co‐express IFNγ (with IL‐17) in highly inflammatory settings, ie, upon stimulation with high amounts of IL‐1β and IL‐23, or in an ovarian cancer microenvironment.84 This evidence concerns the gene IL17A and ovarian cancer.
