免疫复合物的形成是抗体免疫反应、识别抗原的证据,也可以认为免疫复合物是一个与抗疾病免疫反应有关的标志。研究表明,免疫复合物不仅在血管炎病因中起重要作用,而且在一些其他疾病,特别是恶性肿瘤中,它通过抑制淋巴细胞的功能而对宿主产生不良作用。循坏免疫复合物的复杂性不仅向我们提出了有关它的来源、结构及其在病理过程中的作用问题,而且提出了它与免疫系统其它成分特别是活化补体系统的关系等问题。 Immune complex formation is the immune response of the antibody, evidence of antigen recognition, immune complexes can also be considered as a sign of anti-disease immune response. Studies have shown that immune complexes play an important role not only in the etiology of vasculitis, but also in some other diseases, particularly malignancies, that exert an adverse effect on the host by inhibiting the function of lymphocytes. The complexity of circulating immune complexes not only raises questions about its origin, structure and its role in the pathological process, but also raises the question of its relationship with other components of the immune system, particularly the activated complement system.
