目的:探讨青藤碱(SIN)在诱导大鼠来源树突状细胞(DCs)中发挥免疫抑制作用的可能机制。方法:体外培养Wistar大鼠骨髓来源前体细胞，显微镜下观察青藤碱处理DCs(青藤碱修饰组，SIN组)与常规诱导DCs(常规诱导组，对照组)的形态学差异，利用流式细胞术检测DCs的CD表型特点。以脂多糖(LPS)刺激诱导DCs成熟，采用流式细胞术检测青藤碱对LPS诱导的树突状细胞表面Toll样受体(TLR)2、TLR3、TLR4表达的影响。结果:常规诱导组可见细胞呈葡萄串样的细胞集落或悬浮生长，细胞表面颗粒感明显；而青藤碱诱导组细胞集落在一起，细胞体积、形态无明显变化。常规诱导组中DCs表面CD80、CD86的相对表达量为70.7%、71...

Objective:To investigate the mechanism of sinomenine (SIN) in inducing the immunosuppressive effects of rat-derived dendritic cells (DCs).Methods:The bone marrow-derived precursor cells from Wistar rats were cultured in vitro. The morphological differences between sinomenine treated DCs (sinomenine modified group, SIN group) and conventional induced DCs (conventional induced group, control group) were observed under microscope. The CD phenotype of DCs was detected by flow cytometry. DCs were induced maturation by lipopolysaccharides (LPS) sti...
