树突状细胞(DC)浸润是大多数人类肿瘤的共同特征。评估DC与肿瘤的相互作用的先前研究主要集中在它们的免疫学特性上(综述参见Banchereau,J.,和R. M。斯坦曼1998.自然392:245-252)。在这项研究中,我们表明,克隆形成的几个人肿瘤细胞系和原发性肿瘤细胞从骨髓瘤患者的增强与DC的相互作用。在DC存在下培养的骨髓瘤细胞具有改变的表型,其中缺乏终末浆细胞分化标记物CD 138的细胞比例增加。DC-肿瘤相互作用还导致骨髓瘤细胞中B细胞淋巴瘤6表达的上调。通过阻断NF-κ B受体活化剂(RANK)-RANK配体和B细胞活化因子-APRIL(一种增殖诱导配体)介导的相互作用,可抑制DC对骨髓瘤细胞的作用。总之,这些数据表明肿瘤-DC相互作用可能直接影响人类肿瘤的生物学,特别是多发性骨髓瘤,并且可能是治疗干预的靶点。
Infiltration by dendritic cells (DCs) is a common feature of most human tumors. Prior studies evaluating the interaction of DCs with tumors have focused largely on their immunologic properties (for review see Banchereau, J., and R.M. Steinman. 1998. Nature. 392:245–252). In this study, we show that the clonogenicity of several human tumor cell lines and primary tumor cells from myeloma patients is enhanced by their interactions with DCs. Myeloma cells cultured in the presence of DCs have an altered phenotype with an increased proportion of cells lacking terminal plasma cell differentiation marker CD138. DC–tumor interaction also leads to the up-regulation of B cell lymphoma 6 expression in myeloma cells. Effects of DCs on myeloma cells are inhibited by blockade of the receptor activator of NF-kB (RANK)–RANK ligand and B cell–activating factor–APRIL (a proliferation-inducing ligand)-mediated interactions. Together, these data suggest that tumor–DC interactions may directly impact the biology of human tumors, particularly multiple myeloma, and may be a target for therapeutic intervention.
