Abstract

Passive immunotherapy of cancer (i.e., transfer of T cells or antibodies) can lead to some objective clinical responses, thus demonstrating that the immune system can reject tumors. However, passive immunotherapy is not expected to yield memory T cells that might control tumor outgrowth. Active immunotherapy with dendritic cell (DC) vaccines has the potential to induce tumor-specific effector and memory T cells. Clinical trials testing first-generation DC vaccines pulsed with tumor antigens provided a proof-of-principle that therapeutic immunity can be elicited. Newer generation DC vaccines are built on the increased knowledge of the DC system, including the existence of distinct DC subsets and their plasticity all leading to the generation of distinct types of immunity. Rather than the quantity of IFN-gamma-secreting CD8(+) T cells, we should aim at generating high-quality, high-avidity, polyfunctional effector CD8(+) T cells able to reject tumors and long-lived memory CD8(+) T cells able to prevent relapse.

摘要

癌症的被动免疫疗法(即T细胞或抗体的转移)可导致一些客观的临床反应,从而证明免疫系统能够排斥肿瘤。然而,被动免疫疗法预计不会产生可能控制肿瘤生长的记忆T细胞。使用树突状细胞(DC)疫苗的主动免疫疗法有潜力诱导肿瘤特异性效应T细胞和记忆T细胞。对用肿瘤抗原脉冲处理的第一代DC疫苗进行的临床试验提供了一个原理证明,即可以引发治疗性免疫。新一代DC疫苗建立在对DC系统的更多了解之上,包括不同DC亚群的存在及其可塑性,所有这些都导致产生不同类型的免疫。我们的目标不应是分泌γ干扰素的CD8(+) T细胞的数量,而应是产生能够排斥肿瘤的高质量、高亲和力、多功能效应CD8(+) T细胞以及能够预防复发的长寿记忆CD8(+) T细胞。
