Abstract

The plaque-forming cell (PFC) responses to sheep red blood cell (SRBC) dinitrophenyl-lysine-Ficoll (DNP-lys-Ficoll), and dinitrophenylated bovine serum albumin (DNP-BSA) have been studied in both germ-free and conventionally reared ICR mice. In germ-free mice, the IgG response to SRBC and the IgM and IgG responses to DNP-BSA were lower than in conventional mice, but no difference was observed in the IgM response to SRBC or the IgM and IgG responses to DNP-lys-Ficoll. Further, the number of 0-bearing cells in the spleen was smaller, and the mitogenic response of spleen cells to PHA was lower in germ-free mice than in conventional mice. These observations suggest that T cells of germ-free mice remain functionally immature.

摘要

在无菌饲养和常规饲养的ICR小鼠中,研究了对绵羊红细胞(SRBC)、二硝基苯基赖氨酸-聚蔗糖(DNP-lys-Ficoll)和二硝基苯基化牛血清白蛋白(DNP-BSA)的空斑形成细胞(PFC)反应。在无菌小鼠中,对SRBC的IgG反应以及对DNP-BSA的IgM和IgG反应低于常规小鼠,但对SRBC的IgM反应或对DNP-lys-Ficoll的IgM和IgG反应未观察到差异。此外,无菌小鼠脾脏中含0细胞的数量较少,且脾脏细胞对PHA的促有丝分裂反应低于常规小鼠。这些观察结果表明,无菌小鼠的T细胞在功能上仍未成熟。
