Abstract

An innate immune response is essential to mobilize protective immunity upon the infection of respiratory epithelial cells with influenza A virus (IAV). The response is classified as early (nonspecific effectors), local systematic (effector cells recruitment) and late (antigen to lymphoid organ transport, naive B and T cells recognition, effector cells clonal expansion and differentiation). Virus particles are detected by the host cells as non-self by various sensors that are present on the cell surface, endosomes and cytosol. These sensors are collectively termed as pattern recognition receptors (PRRs). The PRRs distinguish unique molecular signatures known as pathogen-associated molecular pattern, which are present either on the cell surface or within intracellular compartments. PRRs have been classified into five major groups: C-Type Lectin Receptor (CLR), Toll-like receptor (TLR), Nod-like receptor (NLR), Retinoic acid-inducible gene-I-like receptor (RLR), which play a role in innate immunity to IAV infection, and the pyrin and hematopoietic interferon-inducible nuclear (PYHIN) domain protein. Here, we discuss the role of PRRs in cellular infectivity of IAV and highlight the recent progress.

摘要

固有免疫反应对于呼吸道上皮细胞感染甲型流感病毒(IAV)时动员保护性免疫至关重要。该反应分为早期(非特异性效应物)、局部系统(效应细胞募集)和晚期(抗原向淋巴器官转运、幼稚 B 和 T 细胞识别、效应细胞克隆扩增和分化)。宿主细胞通过存在于细胞表面、内体和细胞质中的各种传感器将病毒颗粒识别为非自身。这些传感器统称为模式识别受体(PRRs)。PRRs 区分存在于细胞表面或细胞内隔室中的独特分子特征,称为病原体相关分子模式。PRRs 分为五类:C 型凝集素受体(CLR)、 Toll 样受体(TLR)、Nod 样受体(NLR)、视黄酸诱导基因 I 样受体(RLR),它们在 IAV 感染的固有免疫中发挥作用,以及 pyrin 和造血干扰素诱导核(PYHIN)域蛋白。在这里,我们讨论了 PRRs 在 IAV 细胞感染性中的作用,并强调了最近的进展。
