SV40-transformed mKSA cells (H-2d) readily induce progressively growing tumors in adult syngeneic BALB/c mice while expressing the full complement of H-2d MHC class I antigens. BALB/c mice previously immunized with SV40, soluble SV40 T antigen, or irradiated SV40-transformed syngeneic, allogeneic, or xenogeneic cells reject an mKSA tumor challenge even(More)
Simian virus 40 (SV40) has been shown to be associated with a number of human tumours. Two other human papova viruses, BKV and JCV, infect humans at a relatively high frequency and are activated upon immune suppression. The T antigens of both of these viruses share considerable homologies with the transforming protein T antigen of SV40. We have used SV40 T(More)
Viral oncogenes, mutated cellular oncogenes, or other adventitious agents that might contaminate vaccine preparations on inoculation of the host will encounter a T cell-mediated immune response which will play a determining role in the progression of neoplastic events or replication of contaminating viral agents. Using SV40 T antigen tumour systems as a(More)
