| 背景说明 | CD40 is a Type I Transmembrane Glycoprotein that belongs to the TNF Receptor Superfamily.CD40 is expressed in B cells,follicular dendritic cells,dendritic cells,activated monocytes,macrophages,endothelial cells,vascular smooth muscle cells,and several tumor cell lines.The extracellular domain of CD40 is characterized by Cysteine rich repeat regions.Interaction of CD40 with its ligand (CD40L) leads to aggregation of CD40 molecules,which in turn interact with cytoplasmic components to initiate signaling pathways.Several different TRAF proteins (adaptor proteins) have been identified to serves as mediators of the signal transduction.CD40 plays an essential role in mediating a broad variety of immune and inflammatory responses including T cell-dependent immunoglobulin class switching,memory B cell development,and germinal center formation. |

重要的作用是促使细胞因子的高效分泌,因为Th2一旦靠拢B细胞并获得激活信号之后,胞质中的细胞骨架蛋白和专司分泌功能的细胞器(如高尔基体)通过微管组织中心。 3.CD40-CD40L的配接具有重要意义 一系列实验提示CD40L-CD40在B细胞应答中十分重要:①单用T细胞分泌的细胞因子,不能完成T细胞的辅助功能;②活化的Th细胞,用化学试剂固定的方法终止其产生细胞因子,仍然可以诱导B细胞增殖。甚至单用提取的活化Th的细胞膜,也能活化B细胞;③抗CD40L的抗体可以封闭T细胞依赖的B
