Abstract

T-cell regulation of pokeweed mitogen (PWM)-induced polyclonal immunoglobulin (Ig) production was studied in mice. Under optimal stimulating conditions, about 1000 Ig-producing cells were generated per 3 x 10(5) spleen cells and macrophages were required to generate Ig-producing cells from B lymphocytes. The response of splenic B cells to PWM was partially dependent upon helper T cells, whereas the response to lymph node B cells was completely dependent upon T cells. Helper activity was attributed not only to Lyt 1+ 2- but also to Lyt 1+ 2+ T cells. Co-operation between T and B cells, in this system, was not restricted by H-2 barrier.

摘要

在小鼠中研究了T细胞对商陆丝裂原(PWM)诱导的多克隆免疫球蛋白(Ig)产生的调节作用。在最佳刺激条件下,每3×10⁵个脾细胞约产生1000个产生Ig的细胞,并且需要巨噬细胞从B淋巴细胞产生产生Ig的细胞。脾B细胞对PWM的反应部分依赖于辅助性T细胞,而对淋巴结B细胞的反应则完全依赖于T细胞。辅助活性不仅归因于Lyt 1⁺2⁻ T细胞,也归因于Lyt 1⁺2⁺ T细胞。在该系统中,T细胞和B细胞之间的合作不受H-2屏障的限制。
