近20年来通过对树突状细胞(dendritic cells,DC)的研究,学者们逐渐认识到DC是目前发现的功能最强的抗原提呈细胞,DC是启动、调控、并维持免疫应答的中心环节。成熟活化的DC除了与初始型T细胞相互作用诱导抗原特异性细胞毒性T淋巴细胞外,还可以通过直接或间接方式影响B细胞的增殖,活化体液免疫应答;
In the past 20 years, through research on dendritic cells (DC), scholars have come to realize that DC is the most powerful antigen presenting cell that is currently found. DC is the central point of initiation, regulation and maintenance of immune response . Mature activated DC can not only induce antigen-specific cytotoxic T lymphocytes by interacting with naive T cells, but also directly or indirectly affect the proliferation of B cells and activate the humoral immune response.
