Abstract

Tumour populations from two B cell neoplasms were investigated for their capacity to synthesise immunoglobulin in vitro. Neoplastic cells from a patient with chronic lymphocytic leukaemia and an IgG lambda paraproteinaemia co-expressed surface IgG lambda and IgM lambda and synthesised both IgG lambda and IgM lambda in short-term culture. In the second patient with non-Hodgkin's lymphoma, the neoplastic cells expressed surface IgM lambda but synthesised both IgM lambda and IgG lambda in vitro. The findings are discussed in terms of a model for the clonal switch from IgM to IgG synthesis.

摘要

对来自两种B细胞肿瘤的肿瘤群体进行了体外合成免疫球蛋白能力的研究。一名慢性淋巴细胞白血病合并IgG λ副蛋白血症患者的肿瘤细胞共表达表面IgG λ和IgM λ,并在短期培养中合成了IgG λ和IgM λ。在第二名非霍奇金淋巴瘤患者中,肿瘤细胞表达表面IgM λ,但在体外合成了IgM λ和IgG λ。根据从IgM合成向IgG合成的克隆转换模型对这些发现进行了讨论。
