先天性DNA敏感受体是一类模式识别受体,在抗病毒感染,特别是DNA病毒感染中起重要作用。在多种DNA传感器中,cGAS已被深入研究,并且在哺乳动物中定义最多。然而,鸡中的DNA传感器还没有得到太多的研究,鸡cGAS仍然没有完全了解。在本研究中,我们研究了鸡cGAS-STING信号轴,揭示了其协同活性,种属特异性和cGAS中的信号必需位点。重要的是,cGAS和STING都表现出对DNA病毒、逆转录病毒和RNA病毒的抗病毒作用,表明了广泛的抗病毒功能和在鸡先天免疫中的关键作用。
The innate DNA sensing receptors are one family of pattern recognition receptors and play important roles in antiviral infections, especially DNA viral infections. Among the multiple DNA sensors, cGAS has been studied intensively and is most defined in mammals. However, DNA sensors in chickens have not been much studied, and the chicken cGAS is still not fully understood. In this study, we investigated the chicken cGAS-STING signal axis, revealed its synergistic activity, species-specificity, and the signal essential sites in cGAS. Importantly, both cGAS and STING exhibited antiviral effects against DNA viruses, retroviruses, and RNA viruses, suggesting the broad range antiviral functions and the critical roles in chicken innate immunity.
