Abstract

T-B collaboration has been studied in a secondary response to sheep erythrocytes using either syngeneic or allogeneic T- and B-cell combinations. T cells prepared from tetraparental bone marrow chimeras (TBMC), carrying H-2 determinants of one parental strain only, cooperated with syngeneic, as well as with allogeneic B cells carrying the alloantigens to which the T cells had been tolerized in the chimeric environment. When TBMC-derived cells of a single H-2 specificity were transferred with a mixture of TBMC-derived B cells of both H-2 types of the parental strains, no preference for syngeneic cooperation was found. The data therefore suggest that the presence of differing H-2-complex determinants on the allogeneic T- and B-cell populations of the two different strain combinations tested do not interfere with T-B collaboration when the cell populations studied are mutually tolerant.

摘要

在对绵羊红细胞的二次应答中,使用同基因或异基因T细胞与B细胞组合研究了T-B协作。从仅携带一个亲本品系H-2决定簇的四亲代骨髓嵌合体(TBMC)制备的T细胞,与同基因B细胞以及携带T细胞在嵌合环境中已耐受的同种异体抗原的异基因B细胞协作。当单一H-2特异性的TBMC来源细胞与来自亲本品系两种H-2类型的TBMC来源B细胞混合物一起转移时,未发现对同基因协作有偏好。因此,数据表明,在所测试的两种不同品系组合的异基因T细胞和B细胞群体上存在不同的H-2复合决定簇,当所研究的细胞群体相互耐受时,不会干扰T-B协作。
