Abstract:
[摘 要] 肿瘤免疫细胞疗法展现了良好的临床抗肿瘤前景。树突状细胞(DC)识别肿瘤抗原作为机体免疫响应的关键起始步骤,捕获肿瘤抗原后分化成熟,在淋巴结将抗原信号提呈给CD4+ T细胞、CD8+ T细胞等免疫细胞,激发抗肿瘤效应,应用于肿瘤治疗,尤其是实体瘤,被寄予厚望。但由于实体瘤TME复杂的结构特点、DC和T/B细胞免疫响应的机制不清晰等问题犹如崇山峻岭摆在眼前,故未能形成关键理论和技术突破。以CAR-T细胞为代表的精准细胞免疫疗法已表现出优势,但仍面临抗原选择瓶颈。DC治疗性疫苗在临床试验中表现出良好的疗效和安全性,随着DC在TME中关键作用机制的进一步揭示,研究者的目光重新聚焦在DC抗肿瘤效应,推动着DC与其他手段的联合疗法、工程化DC疫苗等实体瘤治疗方案从基础向临床转化,目前正迈入DC临床治疗实体瘤的新阶段。本文系统地对DC治疗实体瘤的临床研究进展、实体瘤TME中DC的种类及其抗肿瘤机制、工程化DC疫苗,以及面临的挑战和应对策略等问题进行了评述。
