The ability of thymus-derived lymphocytes (T cells) from BALB/c mice to recognize the individually specific antigenic determinants (idiotypes) of BALB/c myeloma proteins was tested. Spleen cells from donor mice immunized with a given myeloma protein greatly augmented the response of hapten-specific bone marrow-derived, thymus-independent lymphocytes (cells) to a hapten conjugate of the immunizing myeloma protein. This helper effect was specific for the myeloma protein idiotype; responses to hapten conjugates of similar myeloma proteins, bearing different idiotypic determinants, were not augmented by these spleen cells. That the helper cell is a T cell was shown by its marked sensitivity to cytolysis with an isoantiserum specific for T cells (anti-Thy-1-2) and complement. The discrimination between idiotypes by such T cells is roughly comparable to that of the antibody produced by the donors of the helper cells.
对来自BALB/c小鼠的胸腺衍生淋巴细胞(T细胞)识别BALB/c骨髓瘤蛋白的个体特异性抗原决定簇(独特型)的能力进行了测试。用给定骨髓瘤蛋白免疫的供体小鼠的脾细胞极大地增强了半抗原特异性骨髓衍生的、不依赖胸腺的淋巴细胞对免疫骨髓瘤蛋白的半抗原偶联物的反应。这种辅助效应对于骨髓瘤蛋白独特型具有特异性;对带有不同独特型决定簇的类似骨髓瘤蛋白的半抗原偶联物的反应,不会被这些脾细胞增强。辅助细胞是T细胞这一点通过其对用T细胞特异性同种抗血清(抗Thy-1-2)和补体进行细胞溶解的显著敏感性得以证明。此类T细胞对独特型的区分与辅助细胞供体产生的抗体的区分大致相当。
