此外发现它还具有抗原提呈作用，在正常细胞中参与折叠错误蛋白到蛋白酶体的提呈；在肿瘤细胞中作为主要的肿瘤排斥抗原，引发针对该肿瘤细胞的特异性免疫反应。 | | 8. | Unfortunately , tumor cells can secrete immunosuppressor factors ( such as il - 10 , tgf - p , vegf ) to interfere with dc maturation and function . to overcome tumor - mediated inhibition of dc maturation and function in vivo , immunopotentiating cytokines ( such as il - 7 , il - 12 ) were used for gene - modification of dc , which has proven to be an efficient way to treat cancer in animal models
虽然有直接瘤内注射dc诱导抗肿瘤免疫效应的报道，但肿瘤局部往往是一个处于高度免疫抑制状态的微环境，肿瘤细胞分泌的可溶性介质（如ill 、 tgf卜vegf等）能抑制dc的分化成熟，下调dc表面共刺激分子的表达和iliz的分泌，从而抑制dc的抗原提呈功能，亦对t细胞功能有显著的抑制作用。 | | 9. | Dendritic cells ( dc ) is the most powerful apc , which can markedly increase the antigen - presentation capacity by maximizing the pepitide - mhc complexes on the cell surface and upregulating the co - stimulatory ligands b7 - 1 and b7 - 2 , adhesion moleculees such as il - 12 that promote full activation of lymphocytes . full activation of antigen - specific t cells requires two signals - one signal coming via the tcr and the other signal through engagment of co - stimulatary molecules . t cells receiving one signal via their tcr are turned off by mhc ( major histocompatibility complex ) , via t cell cd28 binding to b7 on the dc induce tlymphokine and t cell proliferatiion
T细胞介导的细胞免疫在控制肿瘤生长方面发挥着重要作用， t细胞在发挥抗瘤效应(分泌细胞因子和直接杀伤)之前必须先经过活化，体内专职抗原提呈细胞( apc )细胞并使其活化，树突状细胞( dendriticcell , dc )为t细胞的激活提供双重信号， t细胞借助tcr识别由dcmhc分子递交的抗原肽后，通过tcr - cd3复合体传递抗原特异性识别信号(第一信号) ，以cd28为主的t细胞表面辅佐分子识别dc表面b7分子，传递非特异性协同刺激信号(第二信号) ，在机体抗肿瘤免疫应答中处于核心地位。 | | 10. | Dendritic cells are characterized by their ability to efficiently present antigen , and are uniquely equipped to stimulate naive t cell responses . immature dendritic cells acquire antigens from throughout the peripheral body , then migrate to t - lymphocyte - dependent areas of lymph nodes . thus , dendritic cells act as bridges , operating at the interface of innate and acquired immunity
作为机体免疫系统中功能最强的专职性抗原提呈细胞( antigen - presentingcells , apc ) ，树突状细胞( dendriticcells , dc )能高效地摄取、加工处理和提呈抗原，具有较强的迁移能力，并能显著地激活初始型t细胞以启动t细胞免疫应答反应，此外， dc与b细胞以及nk细胞等也存在着相互作用，可见， dc在连接天然免疫和获得性免疫之间起着非常重要的作用。 |
