树突状细胞(Dendritic cells,DC)是获得性免疫和耐受的关键。大多数DC在整个身体的组织中战略性地定位为免疫哨兵,以应对入侵的病原体。分化的DC和它们的前体也在血液中循环,并且可以迅速被招募到攻击部位。在外周组织内,DC收集抗原物质,然后运输到次级淋巴器官,在那里它们与淋巴细胞通信以协调适应性免疫应答。因此,DC的迁移和准确定位对于免疫监测是必不可少的。在这里,我们回顾了分子交通信号,管理DC迁移整个生命周期。
Dendritic cells (DCs) are critical for adaptive immunity and tolerance. Most DCs are strategically positioned as immune sentinels in tissues throughout the body poised to respond to invading pathogens. Differentiated DCs and their precursors also circulate in blood and can get rapidly recruited to sites of challenge. Within peripheral tissues DCs collect antigenic material and then traffic to secondary lymphoid organs where they communicate with lymphocytes to orchestrate adaptive immune responses. Hence, the migration and accurate positioning of DCs is indispensable for immune surveillance. Here, we review the molecular traffic signals that govern DC migration throughout their life cycle.
