B 细胞肿瘤的表面免疫球蛋白为潜在的抗体疗法提供了特定的攻击点。抗独特型抗体归巢于靶肿瘤的能力要求独特型是独特的并且它由肿瘤克隆中的每个细胞表达。我们描述了滤泡性淋巴瘤中改变的独特型的演变,该演变导致单克隆抗独特型抗体逃避了实验室检测。这并不是由于第二个(双克隆)淋巴瘤的出现,因为通过流式细胞术和基因组 DNA(Southern blot)杂交分别测定,所有肿瘤细胞的表型和基因型均相同。所有细胞都表达相同的 B 细胞免疫型并具有恒定量的 IgMk。免疫球蛋白基因DNA单一构型的证明证实了单克隆性,并确定独特型的变化不是新基因重排的结果,而更有可能是由于可变区的体细胞突变——这一过程被认为在B细胞中自然发生。这些数据证明了独特型表达的不稳定性,并确定了 B 细胞肿瘤可能对抗独特型治疗无反应的机制。
The surface immunoglobulin of B-cell neoplasms provides a specific point of attack for potential antibody therapy. The capacity of anti-idiotype antibody to home to the target neoplasm requires that the idiotype be unique and that it be expressed by every cell in the neoplastic clone. We describe the evolution of an altered idiotype in a follicular lymphoma that resulted in escape from laboratory detection by monoclonal anti-idiotype antibody. This was not due to the emergence of a second (biclonal) lymphoma, since all the neoplastic cells were otherwise identical both phenotypically and genotypically, as determined by flow cytometry and genomic DNA (Southern blot) hybridization, respectively. All cells expressed the same B-cell immunotype and bore a constant amount of IgMk. The demonstration of a single configuration of immunoglobulin-gene DNA confirmed monoclonality and established that the change in idiotype was not a result of new gene rearrangements but was more likely due to somatic mutation of the variable region--a process presumed to occur naturally in B cells. These data demonstrate the lability of idiotype expression and define a mechanism by which B-cell neoplasms may become unresponsive to anti-idiotype therapy.
