In addition, we also found that the expression of IFNAR1 was significantly positively correlated with the infiltration of CD4+ T cells, CD8+ T cells, macrophages, neutrophils, and dendritic cells, demonstrating that the high expression of IFNAR1 was closely related to the TME of ccRCC (Figure 6H). The gene discussed is CD4; the disease is nonpapillary renal cell carcinoma.
