环二 GMP 和环二 AMP 是细菌产生的第二信使,影响细菌细胞的存活、分化、定植、生物膜形成、毒力和细菌与宿主的相互作用。在这里,我们表明,在 RAW264.7 巨噬细胞和原代骨髓源性巨噬细胞 (BMM) 中,响应环二 AMP 和环二 GMP 产生 IFNβ 和 IL-6,但不产生 TNF,需要 MPYS(也称为 STING、MITA 和 TMEM173)。此外,MPYS 的表达是干扰素反应因子 (IRF)-3 所必需的,而不是核因子 κB (NFκB) 响应这些细菌代谢物的激活所必需的。我们还证实,MPYS 是感染细胞内病原体单核细胞增生李斯特菌和土拉弗朗西斯菌的培养巨噬细胞产生 I 型干扰素所必需的。然而,在任一病原体的全身感染期间,MPYS 缺乏并不影响受感染脾脏中的细菌负荷。感染对照小鼠和 MPYS−/− 小鼠的血清 IFNβ 和 IL-6 浓度在 24 hpi 时也相似,表明这些病原体在体内感染期间刺激不依赖于 MPYS 的细胞因子的产生。我们的研究结果表明,MPYS 依赖和独立途径的分叉介导细胞质细菌感染的感知。
Cyclic-di-GMP and cyclic-di-AMP are second messengers produced by bacteria and influence bacterial cell survival, differentiation, colonization, biofilm formation, virulence, and bacteria-host interactions. Here, we show that in both RAW264.7 macrophage cells and primary bone-marrow–derived macrophages (BMM) the production of IFNβ and IL-6, but not TNF, in response to cyclic-di-AMP and cyclic-di-GMP requires MPYS (also known as STING, MITA, and TMEM173). Furthermore, expression of MPYS was required for interferon response factor (IRF)-3 but not nuclear factor κB (NFκB) activation in response to these bacterial metabolites. We also confirm that MPYS is required for type I IFN production by cultured macrophages infected with the intracellular pathogens Listeria monocytogenes and Francisella tularensis. However, during systemic infection with either pathogen, MPYS deficiency did not impact bacterial burdens in infected spleens. Serum IFNβ and IL-6 concentrations in the infected control and MPYS−/− mice were also similar at 24 hpi, suggesting that these pathogens stimulate MPYS-independent cytokine production during in vivo infection. Our findings indicate that bifurcating MPYS-dependent and -independent pathways mediate sensing of cytosolic bacterial infections.
