Abstract

CBA/N mice have an X-linked recessive effect that results in the absence of a subpopulation of B cells carrying the Lyb3 surface marker. It has been shown previously that this marker is present on a mature subset of B cells in all mouse strains. In this paper the Lyb3+ B cell population in C57BL/6 mice was analyzed further. This subset of B cells selectively expresses a surface marker controlled by the I-A subregion of the H-2 complex. A cytotoxic antiserum recognizing this marker was raised by immunizing defective (CBA/N X C57BL/6)F1 male mice with C57BL/6 spleen cells. This antiserum also contained noncytotoxic, non-strain-restricted anti-Lyb3 antibodies. The possible functional relevance of this surface marker is discussed.

摘要

CBA/N小鼠具有X连锁隐性效应,导致缺乏携带Lyb3表面标志物的B细胞亚群。先前已表明,该标志物存在于所有小鼠品系的成熟B细胞亚群上。本文进一步分析了C57BL/6小鼠中的Lyb3+B细胞群体。该B细胞亚群选择性表达受H-2复合体I-A亚区控制的表面标志物。通过用C57BL/6脾细胞免疫缺陷型(CBA/N×C57BL/6)F1雄性小鼠,制备了识别该标志物的细胞毒性抗血清。该抗血清还含有非细胞毒性、非品系限制性的抗Lyb3抗体。文中讨论了该表面标志物可能的功能相关性。
