最近的复杂研究提供了关于霍奇金细胞和里德-斯滕伯格细胞(H-RS)的生物学性质和细胞起源的新的、有启发性的、但也是矛盾的和有争议的信息。免疫表型分析显示表型抗原表达存在差异;但是,总的来说,数据表明淋巴细胞表达 T 细胞和/或 B 细胞相关标记物和某些激活抗原,同时缺乏单核细胞-巨噬细胞或其他谱系的免疫学特征。分子遗传学研究已证明 T 细胞受体和免疫球蛋白基因重排方面的异质性发现。只有一小部分案件发生了重新安排;这可能是由于该方法的灵敏度阈值加上恶性细胞的稀缺性。大约一半病例的 Epstein-Barr 病毒 (EBV) 基因组克隆整合到 H-RS 细胞中。这些发现的意义——EBV 是致病因素还是副现象——仍有待阐明。 H-RS 细胞表达各种细胞因子和细胞因子受体的 mRNA 和蛋白质,这表明细胞因子在 HD 的病理生理学中起主导作用。单核和多核H-RS细胞能够进行DNA合成和核分裂;细胞分裂的缺乏导致通过内有丝分裂过程产生多核。迄今为止,仅测试了有限数量的癌基因的突变和表达。 bcl-2 癌基因是否与 HD 相关仍然存在争议。非整倍性和非随机染色体异常是 H-RS 细胞的细胞遗传学分析的结果。然而,尚未发现HD特异的染色体标记。因此,虽然对 EBV 参与、生长因子产生、癌基因表达和染色体异常的研究提供了大量关于 H-RS 细胞性质的新数据,但只有免疫表型和基因分型提供了细胞衍生的一些指示:可能表达癌基因的活化淋巴细胞,可能被 EBV 感染,最有可能产生细胞因子,当然具有多种核型异常。
The most recent sophisticated investigations have provided new and revealing, but also contradictory and controversial information on the biological nature and the cellular origin of Hodgkin and Reed-Sternberg cells (H-RS). Immunophenotypic analyses have shown variable phenotypic antigen expression; but, on balance the data suggest a lymphoid cell expressing T- and/or B-cell-associated markers and certain activation antigens while lacking immunological features of monocytes-macrophages or other lineages. Molecular genetic studies have demonstrated heterogenous findings with respect to rearrangements of T-cell receptor and immunoglobulin genes. Only a small percentage of the cases has rearrangements; this might be due to the threshold of sensitivity of the method combined with the scarcity of the malignant cells. Epstein-Barr virus (EBV) genomes are clonally integrated in the H-RS cells of about half the cases. The significance of these findings--whether EBV is a causative agent or an epiphenomenon--remains to be elucidated. H-RS cells express mRNA and proteins of various cytokines and cytokine receptors implying a predominant role for cytokines in the pathophysiology of HD. The mononuclear and polynuclear H-RS cells are capable of DNA synthesis and nuclear division; the lack of cellular division leads to multinuclearity through the process of endomitosis. Mutations and expression of only a limited number of oncogenes have been tested thus far. Whether the bcl-2 oncogene is involved in HD remains a matter of debate. Aneuploidy and non-random chromosomal abnormalities are the results of cytogenetic analyses of H-RS cells. However, no chromosomal marker specific for HD has yet been found. Thus, while studies of EBV involvement, growth factor production, oncogene expression and chromosomal abnormalities contributed a fair amount of new data on the nature of H-RS cells, only immunophenotyping and genotyping provided some indication of the cellular derivation: an activated lymphoid cell that possibly expresses oncogenes, that probably is infected with EBV, that most likely produces cytokines, that certainly has multiple karyotypic abnormalities.
