ZEB2 expression was positively correlated with infiltration of B lymphocytes (r=0.32, P < 005), CD8+ T cells (r=0.44, P < 005), CD4+ T cells (r=0.46, P < 005), macrophages (r=0.65, P < 005), neutrophils (r=0.73, P < 005) and dendritic cells (r=0.71, P < 005) in NSCLC. This evidence concerns the gene CD8A and non-small cell lung carcinoma.
