Abstract

Dendritic cells (DCs) are a complex network of specialised antigen-presenting cells that are critical initiators of adaptive immunity. Targeting antigen directly to DCs in situ is a vaccination strategy that selectively delivers antigen to receptors expressed by DC subtypes. This approach exploits specific DC subset functions of antigen uptake and presentation. Here, we review DC-targeted vaccination strategies that are designed to elicit effective cross-presentation for CD8 T cell immunity. In particular, we focus on approaches that exploit receptors highly expressed by mouse and human cDCs equipped with superior cross-presentation capacity. These receptors include DEC205, Clec9A and XCR1. Targeting DC receptors Clec12A, Clec4A4 and mannose receptor is also reviewed. Outcomes of DC-targeted vaccination in mouse models through to human clinical trials is discussed. This is a promising new vaccination approach capable of directly targeting the cross-presentation pathway for prevention and treatment of tumours and infectious diseases.

摘要

树突状细胞(DCs)是一种复杂的专业抗原呈递细胞网络,是适应性免疫的关键启动者。将抗原直接靶向原位的 DC 是一种疫苗接种策略,可选择性地将抗原递送给 DC 亚型表达的受体。这种方法利用了特定的 DC 亚群的抗原摄取和呈递功能。在这里,我们综述了旨在引发针对 CD8 T 细胞免疫的有效交叉呈递的靶向 DC 的疫苗接种策略。特别是,我们专注于利用表达于具有优越交叉呈递能力的小鼠和人 cDC 上的高度表达的受体的方法。这些受体包括 DEC205、Clec9A 和 XCR1。我们还综述了靶向 DC 受体 Clec12A、Clec4A4 和甘露糖受体的方法。讨论了通过小鼠模型到人体临床试验的靶向 DC 疫苗接种的结果。这是一种有前途的新疫苗接种方法,能够直接针对交叉呈递途径,用于预防和治疗肿瘤和传染病。
