Many spores from the Firmicutes group are decorated with hair-like structures. Since the 60s, they remained a mystery. @remaut-lab.bsky.social named these fibres ENdospore Appendages (ENAs). Using Cryo-ID, we report the identity, structure and function of F-ENA. www.nature.com/articles/s41...

This paper advances deep proteome sequencing, improving detection of protein variants & isoforms beyond standard shotgun proteomics. By analyzing six human cell lines, it identifies a million unique peptides from 17,717 protein groups, highlighting translation of most alternatively spliced isoforms.

How do intracellular #bacteria breach vacuoles to enter the host cytosol? @leaswistak.bsky.social @matthijnvos.bsky.social @enningalab.bsky.social &co show that #Shigella uses its T3SS system to damage endomembranes via mechanoporation to initiate cytosolic access @plosbiology.org 🧪 plos.io/4jXrr9Z
Left: Group of three T3SS localizing in the same zone of the bacteria surface. T3SS n°1 and 2 contact, deform, and perforate the vacuole membrane at the same spot. T3SS n°1 needle (83 nm) is long and seems to deviate from basal body axis showing that strong constraints between T3SS and the vacuole at are play. The locally relaxed vacuole to bacteria space (~50–55 nm) potentially limits additional damage by the T3SS n°3 needle (56 nm) that only slightly deforms the membrane. Right: Model of initial vacuolar membrane breaching by T3SS-induced mechanoporation. Shigella actively enters host cells in a specialized endomembrane compartment, the vacuole, that is rapidly injured and ruptured for cytosolic access. After host cell entry, the vacuole membrane is intact and tightly juxtaposed to the surface of Shigella, permitting contact between T3SSs and the endomembrane. In the authors’ proposed model, vacuole membrane injury is supported both by the vacuole tightness and the length of individual T3SSs.
