摘要
树突状细胞(DCs)即是体内最有效的专业抗原提呈细胞,也是抗原特异性免疫应答的始动者,具有摄取、加工、递呈抗原至T淋巴细胞的能力,表达高水平的MHCⅠ、Ⅱ和CD80、CD86等共刺激分子,在免疫应答中起关键作用。以DCs为基础的各种疫苗在胃癌免疫治疗中取得了很大的成就。
Dendritic cells are not only the most effective and professional antigen-presenting cells, but also the initiator of antigen-specific immune responses.They can capture, process and present antigens to T lymphocyte and highly express MHC- Ⅰ,MHC- Ⅱ and many other costimulatory molecules such as CD80 ,CD86 and so on . Dendritic cells play a key role in immune responses. Moreover, various vaccines based on DC-achieved a significant success in gastric cancer immunotherapy.
