For the purpose of examining more closely the interaction between T and B lymphocytes, we have developed an in vitro T lymphocyte-dependent B lymphocyte proliferation assay. Proliferation of B lymphocytes in response to antigen was found to depend on the presence of primed T lymphocytes; the B lymphocytes could be derived from nonprimed animals. It appears that these B cells were nonspecifically recruited to proliferate. This nonspecific recruitment, however, was found to be Ir-gene restricted in that B lymphocytes from B10.S mice, which are genetic nonresponders to the polymer Glu60-Ala30-Tyr10 (GAT), could not be stimulated by GAT-primed (responder X nonresponder) F1 T cells. The apparent lack of antigen specificity in the face of Ir gene-restricted T-B interaction may have important implications in our understanding of the recognition unit(s) on T lymphocytes.
为了更深入地研究T淋巴细胞与B淋巴细胞之间的相互作用,我们开发了一种体外T淋巴细胞依赖性B淋巴细胞增殖试验。发现B淋巴细胞对抗原的增殖反应依赖于致敏T淋巴细胞的存在;B淋巴细胞可以来自未致敏的动物。似乎这些B细胞是被非特异性募集来增殖的。然而,发现这种非特异性募集受Ir基因限制,因为来自B10.S小鼠的B淋巴细胞,它们对聚合物Glu60-Ala30-Tyr10(GAT)是遗传无反应者,不能被GAT致敏的(反应者×无反应者)F1 T细胞刺激。面对Ir基因限制的T-B相互作用时明显缺乏抗原特异性,这可能对我们理解T淋巴细胞上的识别单位具有重要意义。
