局部抗原应用是当前疫苗研究的热点。这种免疫途径模拟穿过屏障组织的天然抗原暴露,并产生用于皮肤选择性归巢的T细胞印记。通过该途径引入的可溶性抗原需要DC的交叉呈递以产生CD 8 T细胞应答。在这里,我们已经探讨了各种皮肤来源的DC亚群的相对贡献交叉启动和皮肤选择性印迹。在我们的模型中,DC在体内从免疫的小鼠皮肤中获得可溶性Ag,用于体外交叉呈递给幼稚的CD 8 T细胞。我们发现CD 11b+迁移性DC是该模型中相关的交叉致敏DC。Langerin+和Langerin-CD 11b+迁移性DC都可以在我们的系统中交叉呈递抗原,但只有Langerin+亚群可以诱导皮肤选择性地址素E-选择素配体的表达。因此,CD 11b + Langerin+迁移性DC群体主要由朗格汉斯细胞组成,两者都交叉致敏幼稚CD 8 T细胞并使其具有皮肤归巢能力。
Topical antigen application is a focus of current vaccine research. This immunization route mimics natural antigen exposure across a barrier tissue and generates T cells imprinted for skin-selective homing. Soluble antigens introduced through this route require cross-presentation by DC to generate CD8 T cell responses. Here we have explored the relative contribution of various skin-derived DC subsets to cross-priming and skin-selective imprinting. In our model, DC acquire soluble Ag in vivo from immunized murine skin for cross-presentation to naïve CD8 T cells ex vivo. We find CD11b+ migratory DC to be the relevant cross-priming DC in this model. Both Langerin+ and Langerin- CD11b+ migratory DC can cross-present antigen in our system, but only the Langerin+ subset can induce expression of the skin-selective addressin E-selectin ligand. Thus, the CD11b+ Langerin+ migratory DC population, comprised primarily of Langerhans cells, both cross-primes naïve CD8 T cells and imprints them with skin-homing capabilities.
