[Immunity to embryonal stage-specific antigens in viral carcinogenesis].

The oncogenesis induced by the monkey SA7(C8) adenovirus in CBA/Ca mice has shown that immune responses to embryonal antigens are formed at early stages of the latent period and are preserved for a long time reaching the maximum by the 30th day of the latent period. The observed immune response to early embryonal antigens is considered as a factor of the tumour growth immunostimulation and also as a condition limiting the antitumour immunity.
