单核增生李斯特菌(李斯特菌)在免疫功能低下的宿主中引起机会性感染,死亡率高。对李斯特菌的耐药性取决于免疫反应,免疫系统的中性粒细胞募集到感染部位是早期和关键的一步。小鼠中性粒细胞表达两种G蛋白偶联甲酰肽受体亚型Fpr1和Fpr2,它们识别细菌和宿主来源的趋化分子,包括李斯特菌肽,用于细胞迁移和激活。在这里,我们报道了Fprs的缺乏加剧了感染的严重程度,并增加了感染小鼠的死亡率。其机制涉及中性粒细胞早期向肝脏募集受损,Fpr1和Fpr2是中性粒细胞感知李斯特菌化学引诱信号和产生杀菌超氧化物的唯一受体。因此,Fprs是引导李斯特菌感染小鼠肝脏中性粒细胞浸润的第一波必不可少的哨兵,以有效消除入侵的病原体。
Listeria monocytogenes (Listeria) causes opportunistic infection in immunocompromised hosts with high mortality. Resistance to Listeria depends on immune responses and recruitment of neutrophils of the immune system into infected sites is an early and critical step. Mouse neutrophils express two G protein-coupled formylpeptide receptor subtypes Fpr1 and Fpr2 that recognize bacterial and host-derived chemotactic molecules including Listeria peptides for cell migration and activation. Here we report deficiency in Fprs exacerbated the severity of the infection and increased the mortality of infected mice. The mechanism involved impaired early neutrophil recruitment to the liver with Fpr1 and Fpr2 being sole receptors for neutrophils to sense Listeria chemoattractant signals and for production of bactericidal superoxide. Thus, Fprs are essential sentinels to guide the first wave of neutrophil infiltration in the liver of Listeria-infected mice for effective elimination of the invading pathogen.
