1996 年诺贝尔医学奖:　T 细胞的功能

1996's Nobel Prize in Medicine:Function of T Cell

１９９６年的诺贝尔医学奖颁给两位免疫学家，多蒂尔博士和金克尔勒克尔博士，以表彰他们发现毒杀型Ｔ细胞是如何识别被外来病毒感染的细胞的。他们的发现表明Ｔ细胞的识别需双重承认，一是自己细胞上的组织抗原，另一是外来病毒抗原。而且病毒与自身的组织抗原必须同时出现，才会被Ｔ细胞识别。他们成功的经验说明，科学研究重在创新，要善于通过简单的实验设计来开辟一个新的研究领域。

1996's Nobelists in medicine,Dr.Doherty and Zinkernagel,are honded for a double-key model of immune-cell triggering.They came up with a simple explanation of how the immune system's killer T cells acomplish a key step in fighting off viral infections:distinguishing between virus-infected and normal cells,so that the infected cells can be selectively eliminated.The investigators found that the killer cells recognize not just the virus,but also certain cellular proteins,called MHC,whose function-until then-had been a mystery.Their success suggested that scientists must bring forth new ideas in scientific research.
