Abstract

The cellular basis of the genetic control of the immune response to poly(LTyr, LGlu)-polyDLAla--polyLLys [(T,G)-A--L] in SJL (H-2s, low responder) mice has been investigated using T-cell factors. Thymocytes of SJL origin were educated to (T,G)-A--L and tested for their ability to produce an antigen-specific factor capable of cooperating in vivo with bone marrow cells of either SJL or C3H.SW (high responder) origin. SJL T cells were found to be incapable of producing such a cooperative factor, in contrast with results previously obtained with C3H/HeJ (low responders) and C3H.SW strains. Moreover, SJL bone marrow cells did not produce an antibody response to (T,G)-A--L, even when combined with factor produced by high responder (C3H.SW) mice. Thus, both T and B cells appear to be defective in the SJL strain in the response to (T,G)-A--L.

摘要

利用T细胞因子,对SJL(H-2s,低反应者)小鼠针对聚(L-酪氨酸,L-谷氨酸)-聚-D-丙氨酸-聚-L-赖氨酸[(T,G)-A-L]的免疫应答的遗传控制的细胞基础进行了研究。将源自SJL的胸腺细胞用(T,G)-A-L进行诱导,并检测它们产生能够在体内与源自SJL或C3H.SW(高反应者)的骨髓细胞协同作用的抗原特异性因子的能力。与先前用C3H/HeJ(低反应者)和C3H.SW品系获得的结果相反,发现SJL T细胞无法产生这种协同因子。此外,即使与高反应者(C3H.SW)小鼠产生的因子结合,SJL骨髓细胞也不会对(T,G)-A-L产生抗体应答。因此,在对(T,G)-A-L的应答中,SJL品系的T细胞和B细胞似乎均存在缺陷。
