| 1. | Major histocompatibility complex , mhc
主要组织相容性复合体 |
| 2. | Major histocompatibility complex mhc
主要组织兼容性复合体 |
| 3. | To fight disease , the body s major histocompatibility complex molecules identify a disease as a foreign invader
在选择伴侣的时候，气味起着非常重要的作用，不仅人类是这样，鱼也是如此。 |
| 4. | Major histocompatibility complex ( mhc ) class ii molecules are the predominant presenters of exogenous antigens to t helper cells
主要组织相容性复合体( mhc )类分子可将外源性抗原提呈给t辅助细胞。 |
| 5. | All cells display the chopped - up pieces on proteins called major histocompatibility complex ( mhc ) molecules at the cell surface
细胞会将分解后的碎片，呈现在位于细胞表面称为主要组织相容复体（ mhc ）的蛋白质上。 |
| 6. | 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。 |
| 7. | A miniature swine model of nerve transplantation was used to investigate the effects of preoperative ultraviolet - b ( uv - b ) - irradiated donor alloantigen portal venous infusion and injection of cultured major histocompatibility complex ( mhc ) - matched schwann cells into the nerve graft
本试验通过一个小型的猪的神经移植模型来调查经以下处理后移植物的抗原性：术前紫外线- b照射供体移植物，肝门静脉浸泡神经移植物以及向移植物内注射培育过的主要组织相容性复合物配对雪旺细胞。 |
