This paper designs an epitope-centric nanoparticle vaccine against Streptococcus pyogenes using structural mass spectrometry and deep learning to enhance immunogenicity.

This paper develops a combined systems antigenomics-serology workflow to characterize circulating IgG against Group A Streptococcus, revealing antigen repertoire and functional properties of antibodies in healthy and infected individuals.

This study shows that streptolysin O enhances plasminogen to plasmin conversion by interacting with plasminogen and altering its conformation to increase sensitivity to proteolytic processing.

This study uses multi-modal mass spectrometry to identify a conserved protective epitope in Streptolysin O from S. pyogenes, which could inform vaccine and therapeutic development.
