FUT1 and neoplasm: In this experiment we also tested priming against MG1, by pulsing splenocytes with a defined H-2b restricted rhabdovirus N protein peptide; consistent with the human data from figure 2E, activation of an immune response against tumor was accompanied by an antiviral response, with both responses enhanced in vivo by the addition of αPD-1 to virotherapy (figure 6F).
