Antisera prepared in syngeneic mice by hyperimmunization with intact SV40-transformed mouse cells or with somatic cell hybrids between SV40-transformed human and normal mouse cells exhibit anti-SV40 tumor (T) antigen reactivity. Athymic mice bearing tumors formed by SV40-transformed mouse, human or mouse-human hybrids were not reactive with SV40 T antigen. Anti-thymocyte serum (ATS)-treated mice also lacked T antigen reactivity during suppressive treatment but developed antibody to T antigen after discontinuing ATS treatment and tumor regression. We conclude that that presence of growing tumors in the mouse is not necessary for the production of anti-SV40 T antigen antibodies but that helper thymus-derived cells are essential for the humoral response.
