Catalase protects Penaeus vannamei against WSSV by regulating redox homeostasis.
White spot syndrome virus (WSSV) remains one of the most destructive viral pathogens in shrimp aquaculture. Reactive oxygen species (ROS) are required for innate immune signaling, but uncontrolled ROS accumulation can damage host tissues and compromise antiviral defense. Catalase (CAT) decomposes hydrogen peroxide and...
