Delivery of multiple PspA fragments by CyaA toxoid induces broad protection against Streptococcus pneumoniae

Abstract Streptococcus pneumoniae is a leading cause of lower respiratory tract (LRT) infections and invasive pneumococcal diseases (IPD). Conjugate vaccines are effective against IPD and nasal colonization but offer coverage limited to serotypes included in the formulations. Pne...

Covalently Linked Peptides and Membrane Potential Enable CyaA Segment Translocation

The adenylate cyclase toxin (CyaA) from Bordetella pertussis intoxicates host cells by directly translocating its N-terminal catalytic domain across the plasma membrane; however, the forces driving this unique process remain poorly defined. Here, we dissect the membrane transloca...
