Following, the immune infiltration levels of 28 immune cell types were quantified by ssGSEA (Table S1 and Table S2), Student's t‐test showed CD56bright natural killer cell, CD56dim natural killer cell, central memory CD4 T cell, effector memory CD4 T cell, gamma delta T cell, immature dendritic cell, memory B cell, natural killer T cell, Type 17 T helper cell, and Type 2 T helper cell were infiltrating differently between sunitinib‐treated ccRCC and untreated ccRCC (Figure 2B and Table S3). The gene discussed is CD4; the disease is nonpapillary renal cell carcinoma.
