Abstract
Pseudorabies virus (PRV) poses a significant threat to the global swine industry, characterized by high morbidity and a range of sequelae in infected pigs. Mitochondria serve as a crucial platform for innate immunity, playing a pivotal role in a wide array of antiviral responses. In our recent study, we revealed that PRV infection induces mitochondrial disruption, which in turn triggers PINK1/PARKIN-mediated mitophagy. We also show that this process leads to the degradation of the mitochondrial antiviral signaling protein (MAVS) and the inhibition of antiviral interferon production and signaling, ultimately facilitating viral replication.
