    • Polynucleotides encoding carcinoembryonic antigen (CEA) fusion proteins are provided, the CEA fusion proteins comprising a CEA protein, or functional variant thereof, fused to a substantial portion of an immunoenhancing element. The polynucleotides of the present invention can elicit an immune response in a mammal, which, in preferred embodiments, is stronger than the immune response elicited by a wild-type CEA. The gene encoding CEA is commonly associated with the development of human carcinomas. The present invention provides compositions and methods to elicit or enhance immunity to the protein product expressed by the CEA tumor-associated antigen, wherein aberrant CEA expression is associated with a carcinoma or its development. This invention specifically provides adenoviral vector and plasmid constructs carrying polynucleotides encoding CEA fusion proteins and discloses their use in vaccines and pharmaceutical compositions for preventing and treating cancer.
    • 提供了编码癌胚抗原(CEA)融合蛋白的多核苷酸,包含CEA蛋白或其功能变体的CEA融合蛋白与免疫增强元件的大部分融合。 本发明的多核苷酸可以在哺乳动物中引发免疫应答,在优选的实施方案中,它们比由野生型CEA引起的免疫应答更强。 编码CEA的基因通常与人类癌的发展有关。 本发明提供了引发或增强由CEA肿瘤相关抗原表达的蛋白质产物的免疫的组合物和方法,其中异常CEA表达与癌症或其发展相关。 本发明具体提供携带编码CEA融合蛋白的多核苷酸的腺病毒载体和质粒构建体,并公开了其用于预防和治疗癌症的疫苗和药物组合物中。
