The Clec9A-diphtheria toxin receptor (DTR) transgenic mouse strain provides a robust animal model to study the function of lymphoid organ-resident CD8(+) dendritic cells (DCs) and nonlymphoid organ-specific CD103(+) DCs in infectioous diseases and inflammation. Here we describe some basic protocols for CD8(+)/CD103(+) DC isolation, for their in vivo depletion, and for their characterization by multi-color flow cytometry analysis. As an example for in vivo functional characterization of this DC subset, we present here the experimental cerebral malaria model. Furthermore, we illustrate advantages and pitfalls of the Clec9A-DTR system.
Clec9A-白喉毒素受体(DTR)转基因小鼠品系为研究淋巴器官驻留CD8(+)树突状细胞(DCs)和非淋巴器官特异性CD103(+) DCs在传染病和炎症中的功能提供了一个强大的动物模型。在此,我们描述了一些用于分离CD8(+)/CD103(+) DC、体内清除这些细胞以及通过多色流式细胞术分析对其进行表征的基本方案。作为该DC亚群体内功能表征的一个例子,我们在此展示实验性脑疟疾模型。此外,我们还阐述了Clec9A-DTR系统的优点和缺陷。
