Codon-deoptimized single-round infectious virus for therapeutic and vaccine applications.

ABSTRACT: Coxsackievirus B3 (CVB3) is a major cause of myocarditis and acute pancreatitis, particularly in neonates, in whom infections result in severe symptoms and high mortality rates. Despite the urgent need for effective preventive strategies, no vaccines or therapeutic agents have been developed. Live-attenuated vaccines hold promise for combating viral infections; however, their pathogenicity must be carefully regulated without compromising immunogenicity. Here, we investigated codon deoptimization and defective viral genomes (DVGs) as strategies to modulate CVB3 pathogenicity, while preserving its immune-activating capacity. Codon-deoptimized CVB3s with increased CpG dinucleotide content in their 3CD region were engineered, leveraging the innate immunostimulatory properties of CpG. These mod
