ALL AT II-associated genes (including AQP4, FOXA2, NKX2-1, PGC, SFTPB, SFTPD, CLDN18, and SFTPC) were positively associated with the infiltration of six immune cell types (CD8+ T cells, B cells, CD4+ T cells, macrophages, neutrophils, and dendritic cells; all p < 0.05) in LUSC and positively associated with the infiltration of B cells in LUAD (p < 0.05). Here, CD8A is linked to acute lymphoblastic leukemia.
