For years, dendritic cell (DC) biologists have oscillated between two seemingly antagonistic ideas: functional specialization (division of labor) of DC subsets and plasticity (multitasking). More recently, a third hypothesis is gathering support: crosstalk between functionally distinct DC subsets. This reveals a previously unappreciated hierarchy of organization within the DC system, and provides a conceptual framework to understand how cooperation between functionally distinct, yet plastic, DC subsets can shape adaptive immunity and immunological memory. Here we review the recent advances in this area.
多年来,树突状细胞(DC)生物学家一直在两个看似相互对立的观点之间摇摆不定:DC亚群的功能特化(分工)和可塑性(多功能性)。最近,第三种假说正在获得支持:功能不同的DC亚群之间的相互作用。这揭示了DC系统中一个以前未被重视的组织层次结构,并提供了一个概念框架,以理解功能不同但具有可塑性的DC亚群之间的合作如何塑造适应性免疫和免疫记忆。在这里,我们综述了该领域的最新进展。
