Emerging evidence has revealed the existence of an interferon‐like signaling pathway in invertebrates that is functionally analogous to the vertebrate cGAS‐STING‐IFN‐ISG axis and central to antiviral defense. Crustaceans, as one of the most economically significant taxa in global aquaculture, provide a valuable model for uncovering innate immune mechanisms relevant to host‐pathogen interactions and disease management. In shrim...
