By contrast, expression of IL7R, a marker of naive/memory-like cells absent from most late-activated and exhausted T cells,47 was increased at day 16 (1.7-fold, p = 0.003) compared to baseline (Figure 4D), and IL7R expression at day 16 was strongly associated with tumor reduction (OR = 0.06 [95% CI 0–0.61], p = 0.007) (Figure 4E). Here, IL7R is linked to neoplasm.
