中科院院士施履吉教授经常从分子遗传学和细胞生物学的角度对免疫学发展中的一些前沿领域提出独到和有价值的见解。本文中施教授以简洁的文字阐述了他新近思考的两个与免疫学有关的问题。他很谦虚,只希望以信件往来等非正式形式发表这些见解,但鉴於这些见解的视角独特及其对免疫学及有关技术发展所具有的意义,本刊还是以特约专稿的形式予以刊登。 Chinese Academy of Sciences Professor Shi Gangji often from the perspective of molecular genetics and cell biology of immunology in the development of some of the forefront of the area put forward unique and valuable insights. In this article, Professor Shi elucidates in a concise manner the two immunological issues he recently considered. He is very humble and only wishes to make these observations informally such as correspondence, but in the light of the unique perspectives of these insights and their implications for the development of immunology and related technologies, this publication is also published as a special draft .
