CBA/N小鼠的免疫缺陷是通过B淋巴细胞亚群的异常发育来反映的。然而,目前尚不清楚CBA/N小鼠中的突变基因xid如何影响该亚群的发育。具体来说,目前尚不清楚xid基因是通过对其他细胞的作用提供不适当的发育环境,直接还是间接地影响B细胞亚群的发育。我们用雌性小鼠杂合的两个x染色体基因xid和Pgk-1(磷酸甘油酸激酶-1)来研究这个问题。由于雌性是由于x染色体失活而镶嵌的,因此可以利用两种PGK-1同工酶作为细胞学标记来研究其淋巴细胞对x染色体的选择。我们发现脾脏中的B淋巴细胞倾向于不含xid的x染色体,而其余的脾细胞和其他组织的细胞则不这样。这表明xid直接影响B淋巴细胞,而不是通过它们的发育环境。此外,我们的数据表明,产生IgG1和igg3的细胞的前体可能既少又不同。
The immunodeficiency in CBA/N mice is reflected by abnormal development of a subset of B lymphocytes. However, it is not clear how xid, the mutant gene in CBA/N mice, affects the development of this subset. Specifically, it is not known if the xid gene influences the development of the B cell subset directly or indirectly by providing the improper developmental milieu through effects on other cells. We investigated this question using female mice heterozygous for two x chromosomal genes, xid and Pgk-1 (phosphoglycerate kinase-1). Since females are mosaic because of x chromosome inactivation, their lymphocytes can be studied for the choice of the x chromosome, using the two PGK-1 isoenzymes as the cytological marker. We find that B lymphocytes in the spleen prefer the x chromosome without xid while the remaining splenocytes and cells from other tissues do not. This suggests that xid affects B lymphocytes directly and not through their developmental milieu. Furthermore, our data suggest that the precursors for IgG1- and IgG3-producing cells may be both few and different.
