MITA(也称为STING)是针对胞质DNA的先天免疫应答中的中心衔接蛋白。DNA病毒感染后,MITA从内质网向核周微粒体的细胞运输对于MITA激活和先天性抗病毒反应的发生至关重要。在这里,我们发现SNX 8是DNA触发的下游效应基因和先天免疫应答诱导的组分。用DNA病毒HSV-1感染的Snx 8-/-小鼠表现出较低的血清细胞因子水平和较高的病毒滴度,导致较高的致死率。从机制上讲,SNX 8将III类磷酸肌醇3-激酶VPS 34募集到MITA,这是将MITA从ER运输到核周微粒体所必需的。我们的研究结果表明,SNX 8是一个关键的组成部分,在先天性免疫反应的胞质DNA和DNA病毒。
MITA (also called STING) is a central adaptor protein in innate immune response to cytosolic DNA. Cellular trafficking of MITA from the ER to perinuclear microsomes after DNA virus infection is critical for MITA activation and onset of innate antiviral response. Here we found that SNX8 is a component of DNA-triggered induction of downstream effector genes and innate immune response. Snx8-/- mice infected with the DNA virus HSV-1 exhibited lower serum cytokine levels and higher viral titers in the brains, resulting in higher lethality. Mechanistically, SNX8 recruited the class III phosphatylinositol 3-kinase VPS34 to MITA, which is required for trafficking of MITA from the ER to perinuclear microsomes. Our findings suggest that SNX8 is a critical component in innate immune response to cytosolic DNA and DNA virus.
