We further analyzed whether expression of Kb/p15E or Ld/AH1 epitopes, from a tumor-specific envelope gp70 antigen of an endogenous murine leukemia virus (AKV),27, 28, 29, 30, 31 in RNA-binding model antigens affects priming of effector CD8+ T cells in mice by DNA vaccination. This evidence concerns the gene CD8A and neoplasm.
