A point mutation in duck plague virus gB enhances viral fusogenicity and intercellular dissemination via SNAP25-mediated membrane fusion.
Duck plague virus (DPV) is an alphaherpesvirus that causes significant economic losses to the poultry industry. Glycoprotein B (gB) is the core fusogen mediating membrane fusion during viral entry and cell-to-cell spread, yet the regulatory mechanisms governing gB-induced cell fusion in DPV remain poorly understood. In...
