Induction of alpha-N-acetylgalactosamine-O-serine/threonine (Tn) antigen-mediated cellular immune response for active immunotherapy in mice.


A block in carbohydrate chain elongation of O-glycosylated mucins results in accumulation of alpha-GalNAc O linked to serine or threonine (Tn antigen) in a large percentage of human adenocarcinomas. Immunization of mice with desialylated ovine submaxillary mucin (A-OSM), which contains a large concentration of Tn antigen, provided protection against… (More)
