肿瘤相关性抗原 (TAAs)是在肿瘤细胞内或肿瘤细胞表面的大分子 ,在正常组织中是不可见的或较少集中存在的。目前有许多针对肿瘤进行免疫治疗和基因治疗的TAAs的单克隆抗体 (MAbs)。用主要可识别抗体的TAAs作为肿瘤治疗的靶分子的是各种癌的癌胚抗原 ,包括胃肠道肿瘤中的癌胚抗
Tumor-associated antigens (TAAs) are macromolecules in the tumor cells or on the surface of tumor cells that are not visible or less concentrated in normal tissues. There are many monoclonal antibodies (MAbs) to TAAs for tumor immunotherapy and gene therapy. Targeted with the major recognizable antibody as a target molecule for tumor therapy are the carcinoembryonic antigens of various cancers, including carcinoembryonic antigens in gastrointestinal tumors
