This study examines how glycosylation mutations in the NTD of the SARS-CoV-2 XEC variant affect neutralizing antibody responses, cell-cell fusion, and spike stability.

This study compares vaccine-elicited and naturally elicited antibodies' recognition of HIV-1 fusion peptide sequences, finding that naturally elicited antibodies show greater tolerance to sequence variation.

This study evaluates neutralization, infectivity, and stability of JN.1-derived SARS-CoV-2 subvariants, finding that DelS31 mutation in the NTD reduces nAb titers, impairs infectivity, and increases spike stability.

This study evaluates neutralization resistance, infectivity, and membrane fusion of JN.1-derived SARS-CoV-2 subvariants SLip, FLiRT, and KP.2, identifying key mutations affecting antibody sensitivity and spike function.

A novel Hendra virus variant was identified in Australian horses, showing 83% nucleotide identity to the prototype strain and suggesting potential effectiveness of existing antibodies and vaccines.
