病毒能否在细胞内生存和复制取决于宿主的抗病毒机制。天然免疫(Innate immunity)作为机体抗感染免疫的第一道防线,主要在获得性免疫(Adaptive immunity)活化前,发挥抗感染作用。天然免疫系统的细胞可表达模式识别受体(pattern recognition receptors,PRR),以识别病原体的结构
Whether a virus can survive and replicate in a cell depends on the host’s anti-viral mechanism. Innate immunity, the first line of defense against infectious immunity in the body, exerts its anti-infective effect primarily prior to the activation of adaptive immunity. Cells of the innate immune system express pattern recognition receptors (PRRs) to recognize the structure of the pathogen
