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.
