CD274 and neoplasm: Based on these results, we categorize the tumor-specific subtype with negative associations with PD-L1, CD3, and CD8 as T1(PD-L1-CD3-CD8-), that with positive associations with PD-L1, CD3, and CD8 as T2(PD-L1+CD3+CD8+), that with elevated PD-L1 protein expression as T4(PD-L1+), and the remaining tumor subtype as T3.
