Transforming growth factor β (TGF-β) is critical to the maintenance of intestinal immune homeostasis. Here, we present techniques for analyzing Smad molecules downstream of TGF-β receptor signaling in dextran-sulfate-sodium-induced colitic mice. We describe colitis induction, cell isolation, and flow cytometric cell sorting of dendritic cells and T cells. We then detail intracellular staining of phosphorylated Smad2/3 and western blotting analysis of Smad7. This protocol can be performed on a limited number of cells from many sources. For complete details on the use and execution of this protocol, please refer to Garo et al..
转化生长因子β（TGF-β）对于维持肠道免疫稳态至关重要。在此，我们展示了在葡聚糖硫酸钠诱导的结肠炎小鼠中分析TGF-β受体信号下游Smad分子的技术。我们描述了结肠炎的诱导、细胞分离以及树突状细胞和T细胞的流式细胞术细胞分选。然后，我们详细介绍了磷酸化Smad2/3的细胞内染色以及Smad7的蛋白质印迹分析。该方案可在来自许多来源的有限数量的细胞上进行。有关此方案的使用和执行的完整详细信息，请参考加罗等人的研究。
