CD4 and non-small cell lung carcinoma: We further analyzed the correlation of TSKU expression with the immune infiltration levels of different cells in NSCLC, including LUAD and LUSC, and found that the expression level of TSKU significantly correlated with the levels of infiltrating B cells (cor=-0.232, P=2.58e-07), CD4+ T cells (cor =-0.166, P=2.39e-04), dendritic cells (cor =-0.105, P=2.08e-02), and CD8+ T cells (cor =-0.095, P=3.69e-02) in LUAD (Figure 3A).
