Dendritic cells are central to the development of immunity, as they are specialized in initiating antigen-specific immune responses. In this review, we briefly present the existing knowledge on dendritic cell biology and how their division in different dendritic cell subsets may impact the development of immune responses. In addition, we explore the use of chimeric monoclonal antibodies that bind to dendritic cell surface receptors, with an emphasis on the C-type lectin family of endocytic receptors, to deliver antigens directly to these cells. Promising preclinical studies have shown that it is possible to modulate the development of immune responses to different pathogens when monoclonal antibodies fused to pathogen-derived antigens are used to deliver the antigen to different subsets of dendritic cells. This approach can be used to improve the efficacy of vaccines against different pathogens.
树突状细胞是免疫发育的核心,因为它们专门用于启动抗原特异性免疫反应。在这篇综述中,我们简要介绍了树突状细胞生物学的现有知识,以及它们在不同树突状细胞亚群中的分化如何影响免疫反应的发展。此外,我们还探讨了使用嵌合单克隆抗体来结合树突状细胞表面受体,重点关注内吞受体的 C 型凝集素家族,将抗原直接递送到这些细胞。有前途的临床前研究表明,当将与病原体衍生抗原融合的单克隆抗体用于将抗原递送到树突状细胞的不同亚群时,可以调节对不同病原体的免疫反应的发展。这种方法可用于提高针对不同病原体的疫苗的功效。
