It is shown that GSDMA deficiency increases viral loads but reduces inflammation, tissue damage, and mortality upon infection, suggesting that disease severity is driven more by inflammation than by viral load.
Coronaviruses employ discontinuous transcription to produce canonical subgenomic RNAs (sgRNAs) essential for gene expression. Although TRS-dependent template switching mechanism has been proposed, its structural basis remains poorly defined, and the functional significance of abundant non-canonical sgRNAs persists as a...

The structure of PEDV HNXX-strain spike domain B (S1B) is determined and a strain-specific vulnerable site on the PEDV S-trimer is identified, providing insight into how cell-surface membrane fusion activity may influence viral entry pathway selection and antibody neutralization efficacy.

Porcine reproductive and respiratory syndrome virus (PRRSV) is a significant pathogen in swine, causing substantial economic losses globally. The host acute-phase response to PRRSV infection and its role in antiviral defense remain poorly understood. In this study, we identify serum amyloid A2 (SAA2) as a key acute-pha...
