Ly1 诱导 T 细胞 (Ly1:SI) 激活静息 T 细胞,产生有效的抑制活性。在含有 B 细胞和各种 Lyt T 细胞组(已使用 α Lyt 血清进行正向和/或负向选择)的培养物中,对体外生成的引发的 Ly1:SI 进行了抑制诱导分析。这些实验都重申了之前报道的 Ly123 T 细胞在 Ly1:SI 抑制中的要求,并暗示了第三个 T 细胞亚群,这对于 Ly1:SI 诱导的反馈抑制的完全表达是绝对需要的。该 T 细胞亚群具有细胞表面表型 Ly1- Ly23+ 1J+ Qa-1-。
Ly1 inducer t cells (Ly1:SI) activate resting T cells to generate potent suppressor activity. Primed Ly1:SI generated in vitro were assayed for suppression induction in cultures containing B cells and various Lyt T cell sets that had been positively and/or negatively selected using alpha Lyt sera. These experiments both reaffirm the previously reported requirement for an Ly123 T cell in suppression by Ly1:SI and implicate a third T cell subset, which is absolutely required for the full expression of Ly1:SI-induced feedback suppression. This subset of T cells has the cell surface phenotype, Ly1- Ly23+ 1J+ Qa-1-.
