树突状细胞(DC)是T细胞反应的关键刺激因子。它们为T细胞提供基本信号(表位呈递、促炎细胞因子、共刺激),并启动适应性免疫。因此,它们对于产生T细胞免疫的免疫策略至关重要。树突状细胞对炎症信号的反应通常发生在急性病毒感染的背景下。然而,招募病毒来吸引DC受阻,因为他们倾向于以复杂的免疫规避和抑制策略来攻击DC。在这篇综述中,我们讨论了我们在设计基于重组脊髓灰质炎:鼻病毒嵌合体的载体方面的工作,以有效地靶向和接触DC。我们正在将这种方法与最近研究的常用dsDNA病毒载体平台并列在一起。
Dendritic cells (DCs) are pivotal stimulators of T cell responses. They provide essential signals (epitope presentation, proinflammatory cytokines, co-stimulation) to T cells and prime adaptive immunity. Therefore, they are paramount to immunization strategies geared to generate T cell immunity. The inflammatory signals DCs respond to, classically occur in the context of acute virus infection. Yet, enlisting viruses for engaging DCs is hampered by their penchant for targeting DCs with sophisticated immune evasive and suppressive ploys. In this review, we discuss our work on devising vectors based on a recombinant polio:rhinovirus chimera for effectively targeting and engaging DCs. We are juxtaposing this approach with commonly used, recently studied dsDNA virus vector platforms.
