| description | African swine fever (ASF) is a highly contagious and severe infectious disease caused by African swine fever virus (ASFV). The disease significantly threatens the sustainable development of the global pig industry. Unfortunately, to date, no safe and efficacious vaccines are commercially available except in Vietnam. Antioxidative stress is a critical factor in antiviral strategies. In this study, we show that ASFV infection elevates the level of reactive oxygen species (ROS) and suppresses the nuclear factor erythroid 2-related factor 2 (Nrf2) signaling pathway in vitro and in vivo. Moreover, overexpressing Nrf2 can significantly inhibit ASFV replication. Through high-throughput screening of natural small molecules against ASFV, we identify resveratrol (RES), an Nrf2 activator, as a compound capable of inducing the cellular antiviral responses and effectively inhibiting ASFV replication in primary porcine alveolar macrophages (PAMs). Notably, untargeted metabolomics profiling reveals that glutathione emerges as a primary differential metabolite related to the antiviral activities of RES against ASFV. Mechanistically, RES exerts its antiviral effects and attenuates the elevated level of ROS caused by ASFV infection by inducing the production of reduced glutathione (GSH) via the activation of the Nrf2 signaling pathway. In conclusion, RES exhibits broad efficacy as a potentially effective compound for inhibiting ASFV infection and alleviating the oxidative stress induced by ASFV infection via the Nrf2 signaling pathway. |
