树突状细胞（ｄｅｎｄｒｉｔｉｃ ｃｅｌｌｓ， Ｄ Ｃ）是一类专职的抗原提呈细胞，在抗原的加工提呈、抗原识别及 Ｔ 细胞激活中发挥着重要作用。 Ｄ Ｃ具有在体内外都能直接刺激原初（ｎａｉｖｅ） Ｔ细胞的独特性质。树突状细胞用于肿瘤的免疫治疗涉及诸如肽、蛋白、肿瘤细胞及提取物的体外致敏，肿瘤相关抗原、 Ｒ Ｎ Ａ 或细胞因子的基因转移，与肿瘤细胞形成融合蛋白等。 Ｄ Ｃ疗法是充满希望的肿瘤治疗方案。有关临床实验目前正在进行。 Dendritic cells (DCs) are a class of professional antigen presenting cells that play an important role in antigen processing, antigen recognition, and T cell activation. D C has the unique property of directly stimulating naive T cells both in vitro and in vivo. Immunotherapy for tumors by dendritic cells involves the in vitro sensitization of peptides, proteins, tumor cells and extracts, gene transfer of tumor-associated antigens, RN A or cytokines, and fusion protein formation with tumor cells. D C therapy is a promising cancer treatment program. Related clinical trials are currently ongoing.
