ABSTRACT
Recently, COVID-19 caused by the novel coronavirus SARS-CoV-2 has brought great challenges to world. More and more studies have shown that patients with severe may suffer from cytokine storm syndrome; however, there are few on its pathogenesis. Here we demonstrated coding protein open reading frame 8 (ORF8) acted as a contributing factor during infection. ORF8 could activate IL-17 signaling pathway promote expression of pro-inflammatory factors. Moreover, treatment IL17RA antibody protected mice ORF8-induced inflammation. Our findings helpful understand pathogenesis provide potential target for development therapeutic drugs.
