丹麦科研人员不久前发现一种新的免疫细胞能协助抵抗癌症。他们正据此研制一种新型癌症疫苗,目前正在进行临床试验。人体免疫抑制细胞和癌细胞可以产生一种特殊的双加氧酶,来抑制免疫细胞的攻击性,使其缺乏足够攻击力抵抗癌细胞侵袭,甚至还会被癌细胞吞噬。双加氧酶的存在使现有癌症疫苗的有效性大打折扣。 Not long ago, a Danish researcher discovered a new immune cell that could help fight cancer. They are now developing a new type of cancer vaccine and are currently conducting clinical trials. Human immunosuppressive cells and cancer cells can produce a special type of dioxygenase to suppress the aggressiveness of immune cells, making them lack enough attack power to resist invasion of cancer cells and even being swallowed by cancer cells. The presence of dioxygenase greatly reduces the effectiveness of existing cancer vaccines.
