Low-pH-induced conformational changes in the spike protein promote porcine deltacoronavirus infection by enhancing viral binding efficiency to the porcine aminopeptidase receptor

ABSTRACT Porcine deltacoronavirus (PDCoV) is a critical enteric pathogen causing severe diarrhea in neonatal piglets, with fecal-oral transmission as its primary route. However, the molecular mechanism underlying PDCoV adaptation to the acidic gastric environment of hosts remains elusive. Here, we demonstrate that low-...
