Genetic restrictions in generation and expression of hapten-specific suppressor cells for contact sensitivity were found. Dinitrophenol- (DNP) or trinitrophenol-modified mouse spleen cells (SC) induced suppressors in donors able to transfer suppression to normal recipients. When allogeneic DNP-SC were injected into BALB/c mice, cells were generated which were suppressive only in the allogeneic strain providing the DNP-SC. In contrast, when DNP-BALB/c-SC were injected into BALB/c mice, suppressors were generated which were active both in BALB/c and in allogeneic mice (e.g., CBA). This apparent absence of syngeneic major histocompability complex restriction may be explained by cross reactive T-cell receptors which are VH gene products.
研究发现了对半抗原特异性抑制细胞产生和表达的遗传限制,该抑制细胞用于接触敏感性。二硝基苯酚(DNP)或三硝基苯酚修饰的小鼠脾细胞(SC)在供体中诱导出抑制细胞,这些供体能够将抑制作用传递给正常受体。当将同种异体DNP-SC注射到BALB/c小鼠中时,产生的细胞仅在提供DNP-SC的同种异体品系中具有抑制作用。相反,当将DNP-BALB/c-SC注射到BALB/c小鼠中时,产生的抑制细胞在BALB/c和同种异体小鼠(如CBA)中均具有活性。这种明显缺乏同基因主要组织相容性复合体限制的现象可能由作为VH基因产物的交叉反应性T细胞受体来解释。
