- Example Sentences:
| 1. | Constitutive expression of class ii mhc is restricted to " professional " antigen - presenting cells but can be induced on various tissues by gamma interferon
Mhc -类的组成型表达仅限于“专职性”抗原提呈细胞，但细胞因子如ifn -可引起诱导型类分子表达。 | | 2. | Cells of the immune system taking part in tumor - host interaction include t cells , natural killer cells ( nk cells ) and antigen - presenting cells ( apc , such as dendritic cells , b cells , macrophages )
参与肿瘤免疫的免疫细胞主要有t细胞， nk细胞和抗原提呈细胞( apc ) 。 | | 3. | Dendritic cells ( dc ) are the most potent professional antigen - presenting cells ( apc ) , required for the initiation of immune response . for all that the mechanism of dc functions are not fully elucidated
树突状细胞( dendriticcell ， dc )是一种重要的专职抗原提呈细胞( apc ) ，具有刺激初始型t细胞增殖、启动初次免疫应答的独特功能，是t细胞免疫应答的直接启动者和调控者。 | | 4. | 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。 | | 5. | 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。 | | 6. | To date , there are few successful cases in the immunotherapy of cancer patients . the reasons for this have been the limited availability of tumor - associated antigens ( taa ) and the inability to deliver such antigens in a manner that renders them immunogenic and activates t cell responses in patients with cancer
树突状细胞( dendriticcells ， dc )是抗原提呈细胞( antigenpresentingcells ， apc )的一个特殊群体，虽然在体内数量很少，但其分布十分广泛，是体内功能最强大的apc 。 |
