当前,免疫学最关心的问题之一,不是对异已的认识,而是对自己的认识。随之,人们对于免疫的基本概念,也正在发生着重大的变革,免疫学是在抗传染病的实践斗争中产生的,它所关心的是抗传染保护作用,因此,防御的观点,一开始就在免疫学中占据了支配地位。这样,自然就把免疫的发生完全归因子异已抗原的刺激,把免疫看作是单纯地认识异已并排斥异已的反应,对于自己当然是不认识,不排斥的,因为认识自己的细胞均属“禁忌”之列。 At present, one of the most concerned questions about immunology is not awareness of different people but of oneself. In the ensuing years, there has also been a major revolution in the basic concept of immunity. Immunology, which has arisen in the practical struggle against infectious diseases, is concerned with the role of anti-infectives. Therefore, from the very beginning, In immunology occupy the dominant position. In this way, naturally, the occurrence of immunity is completely attributed to different antigen stimulation, the immune as a simple understanding of different and rejection of different responses, of course, do not know for themselves, not exclusive, because of their own cells Are “taboo” of the list.
