This Cell Surface Protein Just Crashed a Major Pig Virus and It Changes How We Think About Immunity

Porcine epidemic diarrhea virus, better known as PEDV, continues to haunt swine production worldwide. For veterinarians and researchers working in food animal medicine, PEDV is more than a textbook pathogen. It is a virus that devastates neonatal piglets, disrupts supply chains, and keeps biosecurity plans under constant pressure. Now, new research shines a spotlight on an unexpected player in the pig’s innate immune defense system that could reshape how we think about antiviral responses.
