Immunity to transplantable carcinogen-induced fibrosarcomas in B2/B2 chickens. III. Tumor growth inhibition by local delayed hypersensitivity reactions to unrelated antigens.

Abstract

Delayed hypersensitivity (DH) reaction to human Ig, corynebacterium parvum or allogeneic cells at the site of tumor cell injection, suppressed the fibrosarcoma (SCFS) growth in chickens. Spleen cells of SC chickens sensitized to human Ig or C. parvum suppressed SCFS growth when adoptively transferred with tumor cells, but only when the sensitizing antigen… (More)
