Furthermore, in a cohort of 27 DLBCL, the authors found that the number of PD-L1 positive cells was substantially higher in the EBV-positive tumors compared with the EBV-negative ones and it was also increased significantly in the EBV-positive DLBCL cases expressing EBNA2, compared to cases lacking EBNA2 immunostaining [59]. Here, CD274 is linked to diffuse large B-cell lymphoma.
