During the developmental cycle of the pathogenic bacterium Chlamydia trachomatis, non-replicative bacterial cells (elementary bodies, EBs) alternate with replicative forms within membrane-bound inclus...

MemBrain v2 enables streamlined analysis of membranes in cryo-electron tomography by providing user-friendly tools for membrane segmentation, membrane protein localization and spatial analysis, suppor...

Multicellular cyanobacteria have evolved sophisticated cell–cell communication machinery to exchange, synchronize, and coordinate the efforts of individual cells. Analogous to gap junctions that have ...

Using in situ cryo-electron tomography, researchers found a unique ‘arm’ domain on the small subunit of Chlamydomonas chlororibosomes. This discovery suggests that chlororibosome structure is more evo...

Focused ion beam (FIB)-milling has been adapted to thin frozen cells for visualization of macromolecular structures in situ with cryogenic electron microscopy. However, only a few large and abundant c...

Filamentous cyanobacteria rely on septal junctions to coordinate multicellular behavior. Kieninger et al. combine cryo-electron tomography, structure prediction, molecular dynamics simulations, and fu...

The ciliary transition zone gates bidirectional protein trafficking to maintain the specialized ciliary proteome using microtubule doublets as a scaffold. While ciliary axonemal doublets are well-char...

Bacterial contractile injection systems (CIS) mediates cell-cell contacts, but the firing mechanism is unclear. Here, the authors employ a multimodal cryoEM approach and structure guided engineering t...

Bacteria, like eukaryotes, use conserved cytoskeletal systems for intracellular organization. The plasmid-encoded ParMRC system forms actin-like filaments that segregate low–copy number plasmids. In m...

Infective endocarditis (IE) is an understudied biofilm-associated infection. Here, analyses of preclinical and clinical data reveal that the Fsr quorum sensing (QS) system of Enterococcus faecalis is ...

Abstract. Bacterial contractile injection systems (CISs) are multiprotein complexes that facilitate the bacterial response to environmental factors or inte
