4-Hydroxy-3-nitrophenyl (NP) derivatized syngeneic spleen cells injected intravenously stimulate maturation of an antigen-binding, idiotype-bearing induction-phase suppressor cell population, as well as an idiotype-binding anti-idiotype-bearing effector-phase suppressor cell population. Both cell types are present simultaneously in the spleen cell population 7-d after their induction. Furthermore, the cell population with antigen-binding properties can, in the presence of NP-derivatized syngeneic cells, induce a population of effector suppressor cells. The precursors of the effector suppressor population are not sensitive to concentrations of cyclophosphamide which prevented the generation of induction phase suppressor cells. These data provide direct evidence in support of the theory of network regulation of immune suppression. X
静脉注射4-羟基-3-硝基苯基(NP)衍生的同基因脾细胞可刺激具有抗原结合能力、携带独特型的诱导期抑制性细胞群体以及携带独特型结合抗独特型的效应期抑制性细胞群体的成熟。这两种细胞类型在诱导后7天同时存在于脾细胞群体中。此外,具有抗原结合特性的细胞群体在NP衍生的同基因细胞存在的情况下,可诱导效应性抑制细胞群体的产生。效应性抑制细胞群体的前体细胞对环磷酰胺浓度不敏感,而环磷酰胺浓度可阻止诱导期抑制细胞的产生。这些数据为免疫抑制的网络调节理论提供了直接证据。X
