We studied immune response to components of proteasome using sera from patients with various connective tissue diseases by immunoblotting. Then, we found that there is a linkage of autoimmune response among components of proteasome and their binding proteins. In addition, We found that circulating proteasome detected by sandwich type ELISA is significantly associated with autoimmune response to proteasome and its binding proteins. These results suggested that the circulating ubiquitin-proteasome complex binding with autoantigens in association with its biologic function is playing an important role to induce autoimmune response to its binding antigens.

我们通过免疫印迹研究了使用患有各种结缔组织疾病的患者的血清对蛋白酶体成分的免疫反应。然后，我们发现蛋白酶体成分与其结合蛋白之间存在自身免疫反应的联系。此外，我们发现夹心型 ELISA 检测到的循环蛋白酶体与蛋白酶体及其结合蛋白的自身免疫反应显着相关。这些结果表明，与自身抗原结合的循环泛素-蛋白酶体复合物与其生物学功能相关，在诱导对其结合抗原的自身免疫反应中发挥着重要作用。
