            "title": "Antiparallel stacking of Csu pili drives Acinetobacter baumannii 3D biofilm assembly",
            "description": "Many Gram-negative nosocomial pathogens rely on adhesive filaments, known as archaic chaperone-usher pili, to establish stress- and drug-resistant, multi-layered biofilms. Here, we uncover the mechanism by which these pili build three-dimensional (3D) biofilm architectures. In situ analyses of Acinetobacter baumannii biofilms using electron microscopy (EM) reveal an extensive network of ultrathin, flat stacks of archaic Csu pili interconnecting bacterial cells in 3D space. Cryo-EM structures of a single native pilus, pilus pairs, and two types of multi-pilus stacks show that the pili pack into antiparallel sheets, with their rods connected laterally by junctions at their zigzag corners. This antiparallel arrangement ensures that contacts form primarily between pili from interacting cells rather than pili from the same cell. With a remarkably short helical repeat, archaic chaperone-usher pili spontaneously establish a high density of junctions that determines the biofilm’s 3D architecture. Our findings may help develop new therapies against multidrug-resistant bacterial infections by targeting pilus-pilus interactions. Some pathogenic bacteria rely on adhesive appendages, known as archaic chaperone-usher pili, to establish drug-resistant multi-layered biofilms. Here, Malmi et al. use electron microscopy techniques to show that these pili form a network of ultrathin, flat stacks interconnecting bacterial cells, and provide a detailed description of the interactions between pili.",
