微生物在宿主体内诱导先天免疫反应。了解不同的微生物如何通过先天途径控制适应性反应是至关重要的。革兰氏阳性细菌对先天和适应性反应的影响尚不清楚。在此,我们报道了金黄色葡萄球菌诱导IL-10,Th17诱导的细胞因子IL-6和IL-23,趋化因子,并调节树突状细胞标志。金黄色葡萄球菌通过调节人类白细胞抗原DR、CD86和PD-L1来抑制T细胞IL-2应答。干扰素-γ、Src激酶抑制剂或TLR2抗体可阻止金黄色葡萄球菌下调人类白细胞抗原-DR。我们的数据表明,天然的TLR信号诱导适应性免疫反应的多维抑制,这可能是缺乏对细菌或微生物耐受性的保护性免疫的原因之一。IL-10和PD-L1拮抗剂可能会增强对金黄色葡萄球菌和其他微生物疫苗的免疫力。
Microbes induce innate immune responses in hosts. It is critical to know how different microbes control adaptive responses through innate pathways. The impact of gram-positive bacteria on the innate and adaptive responses is unclear. Herein we report that Staphylococcus aureus induces IL-10, Th17-inducing cytokines IL-6 and IL-23, chemokines, and regulates dendritic cell markers. S. aureus inhibits T-cell IL-2 responses through modulation of HLA-DR, CD86 and PD-L1. IFN-gamma, Src kinase inhibitors, or TLR2 antibodies prevented the down-modulation of HLA-DR by S. aureus. Our data demonstrate that innate TLR signaling induces multi-dimensional inhibition of adaptive immune responses, which may contribute to the lack of protective immunity to bacteria or microbe tolerance. IL-10 and PD-L1 antagonists may boost immunity to vaccines for S. aureus and other microbes.
