最近发现一种新型树突状细胞,能够表达自然杀伤细胞和B淋巴细胞的抗原表型,但缺乏浆细胞样树突状细胞和T淋巴细胞的抗原表型,似乎是一种同时拥有自然杀伤细胞与树突状细胞功能的嵌合体,这种细胞被称为可产生干扰素的杀伤性树突状细胞.它既能分泌Ⅰ型和Ⅱ型干扰素并有效地识别和杀伤肿瘤细胞,又能表达MHC-Ⅱ类分子以执行抗原提呈的使命,因而被视为能够连接天然免疫和适应性免疫的重要的肿瘤免疫监视细胞. A new type of dendritic cell has recently been discovered that expresses the antigenic phenotype of natural killer cells and B lymphocytes but lacks the phenotype of plasmacytoid dendritic cells and T lymphocytes and appears to be a natural killer Cells and dendritic cell function of the chimera, this cell is called interferon can produce killer dendritic cells.It can secrete type I and type II interferon and effectively identify and kill tumor cells, and The expression of MHC-II molecules in order to perform the task of antigen presentation, and therefore be considered to be able to connect innate and adaptive immunity of the important tumor immune surveillance cells.
