A mixed leukocyte reaction suppressor factor is produced by spleen cells sensitized in vivo and restimulated in vitro across non-H-2 antigenic barriers. Cells capable of producing this factor appear in the spleens of minor locus-immunized animals later than in animals sensitized to major histocompatibility complex-encoded antigens. However, both H-2 and non H-2-induced factors suppress proliferative responses to any alloantigen. Splenocytes from animals immunized with H-2-identical, minor locus-disparate cells produce suppressor factor in vitro only when restimulated with cells sharing both H-2 and non-H-2 antigens with the in vivo stimulators.
混合淋巴细胞反应抑制因子由体内致敏并在体外跨越非H-2抗原屏障再次刺激的脾细胞产生。能够产生这种因子的细胞在次要位点免疫动物的脾脏中出现的时间比在对主要组织相容性复合体编码抗原致敏的动物中晚。然而,H-2和非H-2诱导的因子均抑制对任何同种异体抗原的增殖反应。用H-2相同、次要位点不同的细胞免疫的动物的脾细胞,仅在与体内刺激物共享H-2和非H-2抗原的细胞再次刺激时,才在体外产生抑制因子。
