(136) utilized xCell to analyze the immune and stromal components of 103 ccRCC samples, integrating transcriptomic and proteomic data to classify ccRCC into four distinct subtypes: CD8+ inflamed tumors, CD8− inflamed tumors, VEGF-high immune desert tumors, and metabolically active immune desert tumors. Here, CD8A is linked to nonpapillary renal cell carcinoma.
