树突状细胞被认为是功能最强的专职抗原提呈细胞。当病毒感染动物体,激活天然免疫信号通路,进而活化树突状细胞。树突状细胞摄取和加工抗原,活化T、B细胞,诱导免疫应答,在调节动物免疫应答中起着重要作用。 Dendritic cells are considered the most potent specialized antigen-presenting cells. When a virus infects an animal’s body, it activates the innate immune signaling pathway, which in turn activates dendritic cells. Dendritic cells uptake and processing antigens, activation of T, B cells, induce immune response, play an important role in the regulation of animal immune response.
