传统的树突状细胞(cDC)是连接先天免疫系统和适应性免疫系统的重要免疫细胞。小鼠 cDC 耗竭是研究这些细胞体内功能的重要方法。在这里,我们报道了一种用于 cDC 耗竭的体内诱导系统,其中切除 loxP 侧翼的 Stop 信号能够在 Zbtb46 (zDClSlDTR) 的控制下表达人白喉毒素受体 (DTR)。通过将 zDClSlDTR 小鼠与 Csf1rCre 驱动线组合,可以特异性地消除 cDC。此外,我们还表明,zDCCre 小鼠可用于产生缺乏特定 cDC 子集的 cDC 特异性条件敲除小鼠(Irf8、Irf4、Notch2)。
Conventional dendritic cells (cDCs) are essential immune cells linking the innate and adaptive immune system. cDC depletion in mice is an important method to study the function of these cells in vivo. Here we report an inducible in vivo system for cDC depletion in which excision of a loxP flanked Stop signal enables expression of the human diphtheria toxin receptor (DTR) under the control of Zbtb46 (zDClSlDTR). cDCs can be specifically depleted by combining zDClSlDTR mice with a Csf1rCre driver line. In addition, we show that zDCCre mice can be used to produce cDC specific conditional knockout mice (Irf8, Irf4, Notch2) which lack specific subsets of cDCs.
