本文综述了免疫球蛋白(I@ gene combinatorial librar!!技术已经导致关于1gG类的人类疾病相关的器官特异性自身抗体的信息的对数增长。Basil Rapoport、Stefano Portolano和Sandra McLachlan综述了越来越多的人类单克隆自身抗体的基因克隆、分析和表达,为了解这些分子的遗传背景和表位库提供了新的视角。人类最常见的器官特异性自身免疫性疾病影响甲状腺和胰腺P细胞。系统性自身免疫的原型是结缔组织疾病、红斑狼疮、硬皮病和类风湿性关节炎。人类自身免疫的第二种分类涉及疾病的发病机制是否被认为主要涉及体液或细胞介导的效应机制。体液成分在针对例如重症肌无力(MG)中的骨骼肌终板和Graves病和桥本甲状腺炎中的甲状腺的自身免疫应答中占主导地位。相比之下,自身免疫性疾病如多发性硬化症被认为主要由细胞免疫应答介导。胰岛素依赖型糖尿病(IDDM)包括在这类细胞介导的,虽然最近的数据表明,体液反应可能比以前认为的更重要。自身抗体的产生,至少是IgG类,依赖于T细胞。尽管如此,剖析体液自身免疫反应的组成部分是确定参与特异性自身抗体产生的抗原特异性(而不仅仅是组织浸润)T细胞的作用的必要先决条件。对于这61 IVUi.~,\一一一!I,LII< L
The recent application of immunoglobulin (I@ gene combinatorial librar!! technology has led to a logarithmic increase in information concerning human, disease-associated, organ-specific autoantibodies of the 1gG class. As reviewed here by Basil Rapoport, Stefano Portolano and Sandra McLachlan, the molecular cloning, analysis and expression of the genes for increasing numbers of these human, monoclonal autoantibodies is providing new insight into the genetic background and epitopic repertoires of such molecules.Human autoimmune disease may be organ specific ot systemic. The most common organ-specific autoimmune diseases in humans affect the thyroid gland and the pancreatic P-cell. The prototypes of systemic autoimmunity are the connective tissue disorders, lupus erythematosus, scleroderma and rheumatoid arthritis. A second classification of human autoimmunity relates to whether the pathogenesis of the disease is considered to involve primarily a humoral or a cellmediated effector mechanism. The humoral component predominates in autoimmune responses against, for example, the skeletal muscle endplate in myasthenia gravis (MG) and the thyroid in Graves’ disease and Hashimoto’s thyroiditis. By contrast, autoimmune diseases such as multiple sclerosis are considered to be mediated primarily by the cellular immune response. Insulin-dependent diabetes mellitus (IDDM) is included in this cell-mediated category, although recent data suggest that the humoral response may be more important than previously considered’. Autoantibody generation, at least of the IgG class, is dependent on T cells. Nevertheless, dissecting out the components of the humoral autoimmune response is an essential prerequisite for determining the role of antigen-specific(not simply tissue-infiltrating) T cells involved in specific autoantibody generation.
