(37) also found that DLBCL patients with high expression of TC PD-L2 (TPS ≥ 25%) had longer OS by multiplex immunofluorescence staining, and that high TC PD-L2 expression (TPS ≥ 25%) and low PD-1 expression on T cells were all associated with CD80 upregulation. This evidence concerns the gene PDCD1 and diffuse large B-cell lymphoma.
