CONCLUSION: Both structural and accessory HCoV-OC43 proteins are able to inhibit antiviral response elements in HEK-293 cells, and to block the activation of different antiviral signaling pathways. Following SeV challenge of HEK-293 cells, the expression of genes involved in the type I IFN and NF-κB signaling pathways was downregulated in the presence of HCoV-OC43 structural or accessory proteins (Fig. 4) . Similar to influenza A NS1 protein, HCoV-OC43 structural (M and N) and accessory (ns2a and ns5a) proteins were able to inhibit the transcriptional activity of antiviral response elements, ISRE, IFN-β promoter, and NF-κB-RE, and to downregulate the expression of several genes involved in the activation of an antiviral response. ./cache/cord-275643-lbikoyo3.txt ./txt/cord-275643-lbikoyo3.txt
