摘要
树突状细胞(DCs)是最具潜能的抗原提呈细胞,它能激活初始型T细胞,在启动抗瘤免疫应答中扮演着重要角色。肿瘤浸润性树突状细胞(TIDCs)反映了荷瘤宿主的抗瘤免疫能力,其浸润密度可能与肿瘤预后有关。TIDC是功能低下或无功能的树突状细胞,肿瘤细胞分泌的免疫抑制因子对其表型特征的改变可能是致使其功能低下的原因。以上研究为DC介导的肿瘤免疫治疗提供了理论基础,并指导人们从不同途径利用DC诱导抗瘤免疫反应,从而达到治疗肿瘤的目的。
As antigen-presenting cells, DCs are the most potent and unique,they can stimulate the primitive T cells. They play a major role in initiating the immune response. Tumor infiltrating dendritic cells (TIDCs) can reflect the antitumor immune capability of the host. The density of TIDC perhaps is associated with the prognosis in some cancers. The disablement of TIDCS is partly due to the phenotype they have. Perhaps it is the immunosuppressive factors secreted by tumor cells that have changed their phenotype.The studies about TIDCs provide the basis for DC-mediated antitumor immune therapy,and suggest the use of DC to treat tumors through different approaches.
