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細胞介導的細胞免疫在控制腫瘤生長方面發揮著重要作用， t細胞在發揮抗瘤效應（分泌細胞因子和直接殺傷）之前必須先經過活化，體內專職抗原提呈細胞（ apc ）細胞並使其活化，樹突狀細胞（ dendriticcell ， dc ）為t細胞的激活提供雙重信號， t細胞藉助tcr識別由dcmhc分子遞交的抗原肽后，通過tcr - cd3復合體傳遞抗原特異性識別信號（第一信號） ，以cd28為主的t細胞表面輔佐分子識別dc表面b7分子，傳遞非特異性協同刺激信號（第二信號） ，在機體抗腫瘤免疫應答中處于核心地位。Macrophage is a kind of immune cell as well as accessory cell. it can function as antiinfection, anticancer, immune response and immunoregulation by phagocytosis, antigen presentation, cytokines secretion, lymphocyte activation, reactive oxygen and no production. it ' s an important part of body immune system
巨噬細胞（ macrophage ）既是免疫細胞，又是輔佐免疫應答細胞，可通過吞噬、抗原呈遞、分泌細胞因子、激活淋巴細胞和產生活性氧、 no等作用而行使抗感染、抗腫瘤、免疫應答和免疫調節作用，是機體免疫系統的重要組成部分。
