中文摘要

与传统抗肿瘤药物相比,纳米载体能够以细胞类型特异性的方式共递送不同的药物。迄今为止,许多基于纳米药物的免疫治疗方法旨在直接靶向和杀伤肿瘤细胞,或作用于抗原提呈细胞(APC)如树突状细胞(DC),以引发肿瘤抗原特异性T细胞应答。调节性T细胞(Treg)通过在APC中诱导促耐受状态并抑制T细胞活化和T效应细胞活性,构成肿瘤治疗的主要障碍。本综述旨在总结基于纳米药物的策略,这些策略旨在靶向并重编程Treg以克服其免疫调节活性,并逆转T效应细胞的耗竭状态。此外,我们还将讨论基于纳米载体的方法,将肿瘤抗原特异性嵌合抗原受体(CAR)引入T细胞以用于CAR-T 细胞治疗,这构成了对以DC为重点的疫苗的补充方法。

In contrast to conventional anti-tumor agents, nano-carriers allow co-delivery of distinct drugs in a cell type-specific manner. So far, many nanodrug-based immunotherapeutic approaches aim to target and kill tumor cells directly or to address antigen presenting cells (APC) like dendritic cells (DC) in order to elicit tumor antigen-specific T cell responses.

Regulatory T cells (Treg) constitute a major obstacle in tumor therapy by inducing a pro-tolerogenic state in APC and inhibiting T cell activation and T effector cell activity. This review aims to summarize nanodrug-based strategies that aim to address and reprogram Treg to overcome their immunomodulatory activity and to revert the exhaustive state of T effector cells.

Further, we will also discuss nano-carrier-based approaches to introduce tumor antigen-specific chimeric antigen receptors (CAR) into T cells for CAR-T cell therapy which constitutes a complementary approach to DC-focused vaccination.
