美国Sloan-Kettering癌症研究所和哥伦比亚大学的研究人员研制了一种针对肿瘤细胞表面糖类的癌症疫苗.癌症疫苗通常针对蛋白,但是蛋白位于癌细胞里面,不是疫苗的良好目标.合适的目标是糖,但是糖分子较小,且较难合成. Researchers at the Sloan-Kettering Cancer Institute and Columbia University in the United States have developed a cancer vaccine that targets tumor cell surface carbohydrates. Cancer vaccines are usually targeted at proteins, but proteins are located in cancer cells and are not a good target for vaccines. The appropriate goal is to Sugar, but smaller sugar molecules, and more difficult to synthesize.
