我于1981年11月至1982年3月到美国一些医学院校进行了教学方面的考察学习,同时也了解了美国近年来细胞免疫学研究工作的主要方向及动态。在此基础上,进行了有关问题的文献复习,对近年细胞免疫学的进展有了一些认识,体会到过去所了解的免疫学有很大的局限性,例如在免疫遗传研究中过分强调了HLA与某类疾病的关系,而比较忽视了遗传因素对免疫反应中的重要意义。又如融合细胞,绝大多数研究家都趋向研究单 From November 1981 to March 1982, I visited some medical schools in the United States for teaching and learning. At the same time, I also learned about the main directions and developments of the research on cellular immunology in the United States in recent years. On this basis, the literature review of the relevant issues, the progress of cellular immunology in recent years have some knowledge, understand the past, there are some limitations of immunology, for example, in the immune genetics study overemphasized the HLA And some diseases, but ignores the importance of genetic factors in the immune response. Another example is the fusion of cells, the vast majority of researchers tend to study single
