CD8A and neoplasm: A similar increase of PD‐1hiTim‐3+ and PD‐1hiTox+ “terminally exhausted” CD8+ T cells were observed in the co‐culture system of purified PB CD8+ T cells and NTCS/TTCS‐conditioned neutrophils (Figure 6B), as well as tumor‐specific CD8+ T cells and NTCS/TTCS‐conditioned neutrophils (Figure 6C).
