To assess immune recognition of HLA-matched EBV-positive cancer cells by allogeneic antigen-specific T cells, we generated six EBV-specific T-cell products using an adenoviral vector encoding truncated EBNA1 protein and multiple LMP1 and LMP2 epitopes as a polyepitope (referred to as AdE1-LMPoly)12 13 36 as outlined in figure 1A. Here, PSMB9 is linked to cancer.
