    Asymptomatic Bordetella pertussis infections in a longitudinal cohort of young African infants and their mothers

    Christopher J Gill et al.
    Longitudinal qPCR-based pertussis surveillance of a low-resource African cohort reveals frequent asymptomatic pertussis infections in both young infants and mothers and suggests possible early warning signals for epidemic outbreaks.

    Bordetella adenylate cyclase toxin is a unique ligand of the integrin complement receptor 3

    Radim Osicka et al.
    A toxin produced by the bacterium Bordetella pertussis preferentially binds to non-activated integrin complement receptor 3 outside of its ligand-binding I-domain and efficiently blocks downstream signaling of the integrin through elevation of cytosolic cAMP.

    Abundant toxin-related genes in the genomes of beneficial symbionts from deep-sea hydrothermal vent mussels

    Lizbeth Sayavedra et al.
    Beneficial symbiotic bacteria encode an exceptional number of toxin-related genes that are all expressed by the symbionts in the host, supporting their key role in host-microbe interactions.

    The fluoride permeation pathway and anion recognition in Fluc family fluoride channels

    Benjamin C McIlwain et al.
    In the extremely selective fluoride channels from the bacterial Fluc family, fluoride ions access the pore via two points, an electropositive vestibule and a triad of conserved residues involved in anion recognition.

    Molecular determinants of permeation in a fluoride-specific ion channel

    Nicholas B Last et al.
    The ion-transport pathway of an unconventional bacterial fluoride channel is mapped out through combined crystallographic and functional experiments.

    Homeostatic control of cell wall hydrolysis by the WalRK two-component signaling pathway in Bacillus subtilis

    Genevieve S Dobihal et al.
    Molecular genetic analyses define the first homeostatic control pathway that maintains cell wall remodeling activity during bacterial growth.

    Cytotoxic T cells swarm by homotypic chemokine signalling

    Jorge Luis Galeano Niño et al.
    Killer T cells swarm around tumour targets by accelerating the recruitment of distant T cells, which upon arrival and target engagement augment the chemotactic signal in a positive feedback loop.

    PrkA controls peptidoglycan biosynthesis through the essential phosphorylation of ReoM

    Sabrina Wamp et al.
    Analysis of suppressor mutants led to the identification of a novel signalling pathway that regulates peptidoglycan biosynthesis in Gram-positive bacteria.
