The paper investigates how early acquisition of S-specific Tfh clonotypes after SARS-CoV-2 vaccination correlates with sustained anti-S antibody levels.

This study identifies a specific CD4+ T-cell cluster associated with reduced pneumonia risk in SARS-CoV-2 patients, suggesting immune imbalance contributes to severe disease.

This study identifies human Dectin-1 as a ligand for CLEC-2, showing its O-glycosylation enables it to function as a physiological ligand for immune regulation.

This study shows that the MexAB-OprM efflux system contributes to intrinsic cefiderocol resistance in Pseudomonas aeruginosa, with MexXY-OprM partially compensating its function.

The paper identifies and crystallizes public TCRs from SARS-CoV-2-specific Tfh cells in COVID-19 patients, showing they recognize conserved spike epitopes and cross-react with symbiotic bacteria.

The paper identifies a new sublineage of Salmonella 4,[5],12:i:-, clade 9-2, which has become dominant in Japanese food animals through genome reductions and antimicrobial resistance.

The paper develops a shorter questionnaire, BPVI, to assess sense of values in Japanese adults, showing it aligns with Schwartz's value theory and is suitable for comparing values across age groups.

This study identifies novel cholera toxin variants and ToxT regulon in Vibrio mimicus strains, suggesting their role in the evolution of hybrid Vibrio cholerae strains.
