我们产生了自身反应性T细胞杂交瘤,其可以通过与同基因脾刺激细胞或同基因Ia阳性B细胞-B淋巴瘤杂交瘤共培养来诱导分泌白细胞介素2。这些自身反应性杂交瘤产生于猪胰岛素致敏的淋巴结T细胞与AKR胸腺瘤BW 5147的融合,并且以比预期的胰岛素特异性杂交瘤更高的频率发生。使用重组菌株的映射研究和使用单克隆抗-Ia抗体的阻断研究将刺激性决定簇定位于主要组织相容性复合体的I-Ad亚区。这些T细胞杂交瘤似乎不针对培养系统中存在的任何外来抗原,因为活化发生在无血清、无胰岛素培养基(Iscove培养基)中。这种杂交瘤应该被证明是一个有效的工具,在研究自身反应的生物学意义和功能。
We produced autoreactive T cell hybridomas that can be induced to secrete interleukin 2 by co-culture with either syngeneic splenic stimulator cells or syngeneic Ia-positive B cell-B lymphoma hybridomas. These autoreactive hybridomas arose from the fusion of pork insulin- primed lymph node T cells with the AKR thymoma BW 5147 and occurred at a higher frequency than the expected insulin-specific hybridomas. Mapping studies using recombinant strains and blocking studies using monoclonal anti-Ia antibodies localized the stimulatory determinant to the I-Ad subregion of the major histocompatibility complex. These T cell hybridomas did not appear to be directed at any foreign antigen present in the culture system because activation occurred in serum- free, insulin-free medium (Iscove's medium). Such hybridomas should prove to be a potent tool in studying the biologic significance and function of the autoreactive response.
