Both the IL-7–ALT CD8+ TEFF and TCM subsets were present in tumor in significantly greater numbers than their IL-2–ALT counterparts (individual subsets for each ALT condition in Figures 3, I and J, comparison between ALT conditions in Figure 3K, IL-7–ALT versus IL-2–ALT TCM and TEFF ****P < 0.0001). Here, IL7 is linked to neoplasm.
