Consistent upregulation of the PD-L1 protein after in vitro infection with a recombinant EBV Akata strain was associated with the EBNA2 expression (but not LMP1) in the EBV-negative BL cell lines OMA4 and DG-75 (RRID: CVCL_0244), as well as the GC-type DLBCL cell lines U-2932 (RRID: CVCL_1896) and SU-DHL-5 (RRID: CVCL_1735). Here, CD274 is linked to diffuse large B-cell lymphoma.
