病毒识别和干扰素(IFN)的诱导是先天免疫系统的关键组成部分。Toll样受体(TLR)和RIG-I样受体家族已被表征为RNA病毒检测中的关键参与者。由这些受体引发的信号级联对于在感染细胞和邻近细胞中建立IFN信号介导的抗病毒状态、遏制病毒复制以及引发适应性免疫应答至关重要。在这篇综述中,我们专注于这些受体的多样性和重叠的功能,它们的生理重要性,以及各自的病毒诱导剂。我们强调TRL 3,TLR 7/8,视黄酸诱导基因I,黑色素瘤分化相关基因5和负责激活这些病毒传感器的RNA分子的作用。
Virus recognition and induction of interferon (IFN) are critical components of the innate immune system. The Toll-like receptor (TLR) and RIG-I-like receptor families have been characterized as key players in RNA virus detection. Signaling cascades initiated by these receptors are crucial for establishment of an IFN signaling mediated antiviral state in infected and neighboring cells and containment of virus replication as well as initiation of the adaptive immune response. In this review, we focus on the diverse and overlapping functions of these receptors, their physiological importance, and respective viral inducers. We highlight the roles of TRL3, TLR7/8, retinoic acid inducible gene I, melanoma differentiation-associated gene 5, and the RNA molecules responsible for activating these viral sensors.
