Having shown that MV-Edm infection sensitized HCC cells to CD8+NKG2D+-mediated oncolysis and that MV-Edm-infected HCC cells improved antitumour immune activation of CD8+NKG2D+ cells, we next wanted to know if MV-Edm could improve CD8+NKG2D+-mediated antitumour efficacy in vivo. The gene discussed is CD8A; the disease is infection.
