免疫反应是机体接触抗原性物质后引起的一种防卫反应,用以保护机体免受外来抗原性物质的侵损。但事物总是一分为二,免疫反应对人体有利,也有害。用免疫血清防治疾病可能引起血清病;有些人对外界某些物质过敏也是免疫反应造成的损害;近年来,自身免疫性疾病的发现,说明异常的免疫反应可使机体造成严重疾病,甚致死亡。一免疫学基础研究的进展近年来免疫学有了很大的进展,兹就与本文有关的问题简介如下。 1.免疫活性细胞:与一种适当的抗原决定簇接触后,可接受刺激而发生反应的细胞称为免疫活性细胞,主要是淋巴系统细胞。淋巴细胞起源于骨髓干细胞,最后生成具有免疫活性的小淋巴细胞(细 Immune response is the body’s exposure to antigenic substances caused by a defensive response to protect the body from foreign antigen material damage. But things are always divided into two, the immune response is beneficial to the human body, but also harmful. In recent years, the discovery of autoimmune diseases, indicating that abnormal immune response can make the body cause serious illness, even fatal. In recent years, autoimmune diseases can cause sero-disease; some people allergic to some of the outside world is also caused by immune reaction damage; . Advances in Basic Research in Immunology There has been a great deal of progress in immunology in recent years. Here is a brief summary of the issues related to this article. 1. Immunocompetent cells: After contact with an appropriate antigenic determinant, cells that are responsive to stimuli are called immunocompetent cells, primarily lymphatic system cells. Lymphocytes originate from bone marrow stem cells and finally produce immunocompetent small lymphocytes
