The co‐localization of neutrophils and CD8+ T cells in the tumoral area of GC tissues (Figure 6A) and the significant negative correlations between the levels of neutrophils and CD8+ T cells in GC tumors analyzed (Figure 6B) suggests that these neutrophils may promote tumor progression by impairing CD8+ T‐cell immunity. The gene discussed is CD8A; the disease is gastric cancer.
