抗原刺激的 Lyl 细胞诱导来自非免疫供体的小鼠 T 细胞产生有效的反馈抑制活性。抑制作用由 Ly23 抑制性 T (Ts) 细胞介导,这些细胞由 Ly23 或 Ly123 前体产生。 Ly23 前体产生的 Ts 活性需要强诱导信号,并且表达迅速但持续时间短。 Ly123 前体的 Ts 活性相对较长,并且由相对较低水平的诱导信号有效产生。 Ly123 和 Ly23 前体细胞诱导成为 Ts 细胞需要两个细胞共享与 Ig-H [Ig-H 链] 基因座相关的基因。
Antigen-stimulated Lyl cells induce [mouse] T cells from nonimmune donors to develop potent feedback suppressive activity. Suppression is mediated by Ly23 suppressor T (Ts) cells, which are generated from either Ly23 or Ly123 precursors. Ts activity generated from Ly23 precursors requires a strong inducer signal and is rapidly expressed but short lived. Ts activity from Ly123 precursors is relatively long lived and is efficiently generated by relatively low levels of inducer signals. Induction of both Ly123 and Ly23 precursors to become Ts cells requires that both cells share genes linked to the Ig-H [Ig-H chain] locus.
