This study identifies two distinct capsid conformations in human norovirus GII.3 virus-like particles, revealing conformational switching and alternative P domain interaction networks.

The paper reports near-atomic cryo-EM structures of human astrovirus serotype 4 in immature and mature states, revealing a subunit-specific maturation mechanism driven by protease accessibility.

This study identifies Oxy229, a compound that disrupts the NTCP-EGFR receptor complex, selectively inhibiting HBV and HDV entry without affecting NTCP or EGFR physiological functions.

The paper genetically classifies 525 Picornavirales genomes and 'picorna-like' viruses using multiple sequence and structural analyses, revealing support for existing families and six novel families, along with 32 new genera.
