    Immune stealth-driven O2 serotype prevalence and potential for therapeutic antibodies against multidrug resistant Klebsiella pneumoniae

    Pennini, Meghan E. ; De Marco, Anna ; Pelletier, Mark ; Bonnell, Jessica ; Cvitkovic, Romana ; Beltramello, Martina ; Cameroni, Elisabetta ; Bianchi, Siro ; Zatta, Fabrizia ; Zhao, Wei ; Xiao, Xiaodong ; Camara, Maria M. ; DiGiandomenico, Antonio ; Semenova, Elena ; Lanzavecchia, Antonio ; Warrener, Paul ; Suzich, JoAnn ; Wang, Qun ; Corti, Davide ; Stover, C.

    Emerging multidrug-resistant bacteria are a challenge for modern medicine, but how these pathogens are so successful is not fully understood. Robust antibacterial vaccines have prevented and reduced resistance suggesting a pivotal role for immunity in deterring antibiotic resistance. Here, we show the increased prevalence of Klebsiella pneumoniae lipopolysaccharide O2 serotype strains in all...

    Structure and function analysis of an antibody recognizing all influenza A subtypes

    Kallewaard, Nicole L. ; Corti, Davide ; Collins, Patrick J. ; Neu, Ursula ; McAuliffe, Josephine M. ; Benjamin, Ebony ; Wachter-Rosati, Leslie ; Palmer-Hill, Frances J. ; Yuan, Andy Q. ; Walker, Philip A. ; Vorlaender, Matthias K. ; Bianchi, Siro ; Guarino, Barbara ; De Marco, Anna ; Vanzetta, Fabrizia ; Agatic, Gloria ; Foglierini, Mathilde ; Pinna, Debora ; Fernandez-Rodriguez, Blanca ; Fruehwirth, Alexander ; Silacci, Chiara ; Ogrodowicz, Roksana W. ; Martin, Stephen R. ; Sallusto, Federica ; Suzich, JoAnn A. ; Lanzavecchia, Antonio ; Zhu, Qing ; Gamblin, Steven J. ; Skehel, John J.

    Influenza virus remains a threat because of its ability to evade vaccine-induced immune responses due to antigenic drift. Here, we describe the isolation, evolution, and structure of a broad-spectrum human monoclonal antibody (mAb), MEDI8852, effectively reacting with all influenza A hemagglutinin (HA) subtypes. MEDI8852 uses the heavy-chain VH6-1 gene and has higher potency and breadth when...
