免疫球蛋白(IG)基因重组在正常B细胞的生成中起着重要作用,而IG基因的体细胞超突变和类别转换是抗原驱动的B细胞分化过程中的关键过程。然而,这些过程的错误参与B细胞淋巴瘤的发展。原癌基因的IG位点相关易位是许多B细胞恶性肿瘤的标志。另外的转化事件包括各种肿瘤抑制基因中的失活突变,以及B细胞被病毒(如EB病毒)潜伏感染。许多B细胞淋巴瘤需要B细胞抗原受体表达,并且在一些情况下,慢性抗原刺激在维持肿瘤生长中起作用。通常,由微环境中的其他细胞提供的存活和增殖信号是淋巴瘤发展和病理生理学中的另一个关键因素。许多B细胞恶性肿瘤来源于生殖中心B细胞,很可能是因为这些细胞的高增殖率和致突变过程的高活性。
Immunoglobulin (Ig) gene remodeling by V(D)J recombination plays a central role in the generation of normal B cells, and somatic hypermutation and class switching of Ig genes are key processes during antigen-driven B cell differentiation. However, errors of these processes are involved in the development of B cell lymphomas. Ig locus-associated translocations of proto-oncogenes are a hallmark of many B cell malignancies. Additional transforming events include inactivating mutations in various tumor suppressor genes, and also latent infection of B cells with viruses, such as Epstein–Barr virus. Many B cell lymphomas require B cell antigen receptor expression, and in several instances chronic antigenic stimulation plays a role in sustaining tumor growth. Often, survival and proliferation signals provided by other cells in the microenvironment are a further critical factor in lymphoma development and pathophysiology. Many B cell malignancies derive from germinal center B cells, most likely because of the high proliferation rate of these cells and the high activity of mutagenic processes.
