以肿瘤疫苗为基础的主动免疫治疗和以T细胞介导的抗肿瘤免疫应答成为肿瘤治疗新的热点,近来发现,肝癌患者癌灶缺乏成熟而有活性的CD8+树突状细胞(dendriticcells,DC),表明肝癌发生过程中有活性DC的浸润作用[1]。DC是机体免疫系统中功能最强的专职性抗原提成细胞(Antigen-presen
Active immunotherapy based on tumor vaccines and T-cell-mediated anti-tumor immune responses have become a new hot spot for cancer therapy. Recently, cancerous foci of patients with liver cancer have been found to lack mature and active CD8+ dendritic cells (DCs). , indicating the invasive action of active DC in the course of liver cancer [1]. DC is the most powerful professional antigenic cell in the immune system (Antigen-presen
