  • Segmented Filamentous Bacteria (SFB) are understudied commensals that promote immune activation through their attachment to the intestinal epithelium. Here, Cruz et al. use cryo-electron microscopy and tomography to identify various surface structures and uncover a developmental transition at the SFB adhesive tip.

  • The architecture of functional TNTs is still under debate. Here, the authors combine correlative FIB-SEM, light- and cryo-electron microscopy approaches to elucidate the structure of TNTs in neuronal cells, showing that they form structures that are distinct form other membrane protrusions.

  • An integrated cryo-imaging pipeline combining cryo-correlative light and electron tomography with cryo-soft X-ray tomography provides 3D cellular context information and improved cryolamellae targeting for in situ cellular studies.

  • A comprehensive analysis of the distribution and evolution of the main outer membrane tethering systems across bacteria, coupled with experimental deletion of one of these systems in Veillonella parvula, provide insights into the transition from diderm to monoderm bacteria

  • Baquero et al. show that extracellular vesicles produced by the dominant human-gut archaeon are likely formed by budding from the cell membrane and released through disruptions in the cell wall, and contain extrachromosomal circular DNA molecules encoding methanogenesis enzymes as well as a proviral genome.

  • The human gut virome includes understudied viruses that infect archaea. Here, Baquero et al. characterize a temperate archaeal virus that infects the dominant methanogenic archaeon of the human gut, shedding light on archaeal virus-host interactions and highlighting similarities with gut bacteriophages in establishing stable coexistence with their hosts.

  • Most archaea divide by binary fission using an FtsZ-based system that is poorly understood. Here, the authors combine structural, cellular, and evolutionary analyses to show that the SepF protein acts as the FtsZ anchor in the archaeon Methanobrevibacter smithii.
