The Immunohistologic Identification of Mononuclear Cells and Ia Antigen in Rabbit Spleen and Thymus by Monoclonal Antibodies

兔子脾臟及胸腺之單核細胞及Ia抗原之鑑別與分怖情形-以免疫組織學利用單株抗體之研究

摘要


兔子的淋巴細胞早已被區分為T淋巴細胞及B淋巴細胞,但是由於缺乏一些特殊的試劑及方法,所以一直無法在它們的分怖及功能上更進一步去了解。近年來發展出一些特殊的單株抗體,可以鑑別及分類兔子脾臟及胸腺細胞中的亞群。 本文係利用五種單株抗體,2C4.B12(可對抗兔子組織中的Ia抗原),L11/135(可對抗兔子組織中所有各種的T淋巴細胞)及L12/27,L12/201,L13/64(可分別對抗免子組織的T淋巴細胞與B淋巴細胞之亞群),以ABC(Avidin-Biotin Complex)的免疫過氧化物酵素法,針對兔子的脾臟及胸腺的組織冷凍切片,探討其組織中T淋巴細胞,B淋巴細胞及Ia抗原(MHC Class-Ⅱ,主要組織移植抗原第二型)的存在與分怖情形。 結果我們發現這五種對抗兔子的老鼠融合瘤細胞的培養液所提析出來的單株抗體可以明確的鑑定及分類兔子的T淋巴細胞,B淋巴細胞與Ia抗原。同時顯而易見的看出兔子的脾臟與胸腺的組織學與人類大致相同。利用此一方法我們將更進一步的探討兔子眼精在正常狀態下與各種不同的發炎狀態下,其T淋巴細胞,B淋巴細胞與Ia抗原的存在與分怖狀況。

Using 5 monoclonal antibodies-2C4.B12 (against rabbit Ia antigen),L11/135 (against rabbit pan-T lymphocyte), L12/27, L12/201,L13/64 (all against T and B lymphocytes subsets) and the ABC (avidin-biotin complex) immunoperoxidase method, the distribution of Ia antigen, T and B lymphocytes in the frozen sections of the rabbit spleen and thymus were studied. The results showed the reaction of these monoclonal antibodies could be clearly observed using this method. The distribution of lymphocyte subpopulation (T and B), and Ia antigen in the rabbit spleen and thymus are nearly the same as that of the human. Future application of this method will continue to study the Ia antigen and mononuclear cell changes in the various condition of rabbit eyes.
