Very interesting work from Ibarlosa and colleagues regarding functional amyloid forming proteins in prokaryotic immunity.

Amyloids in bacterial antiphage defence

Nature Microbiology - Bacterial prions form amyloids in response to phage infection and induce cell death to prevent viral replication, similar to the processes in fungi and across the tree of life.

For the first time, scientists have performed targeted mutations on an episymbiosis-determining pathway. In a new study on Saccharibacteria, AFI researchers used advanced techniques to observe pili that drive motility and host attachment.

New paper out! We searched for cargo across thousands of Type 11 Secretion Systems (T11SS) in Proteobacteria and uncovered 2,500+ predicted secreted proteins, including 6 novel cargo types, with experimental verification of a new surface lipoprotein, Pls. doi.org/10.1099/mgen.0.001406

📣 We are proud of the publication of the second paper of @bbaker24.bsky.social PhD thesis. In collaboration with friends in Halifax we have studied the difficult question of the phylogeny of the DPANN archaea, composed of several phyla of highly reduced, fast-evolving epiparasites 🧵

rdcu.be/erkkU

Phylogenomic analyses indicate the archaeal superphylum DPANN originated from free-living euryarchaeal-like ancestors

Nature Microbiology - Phylogenetic reconstructions with conserved protein markers from the 11 known DPANN phyla reveal their monophyletic placement within the Euryarchaeota.

Exciting progress! In our new preprint, we show that episymbiont Saccharibacteria can directly modulate epithelial immunity—a big step in understanding how these elusive microbes interact with the human host. Kudos to Deepak Chouhan and our amazing collaborators! www.biorxiv.org/content/10.1...

Our findings reveal that the specificity of several FISH probes is compromised, with cross-species hybridization being more common than previously assumed as more genomic data becomes available. #microbiology

"That telomere phages are so prevalent means that they are a selective force, one that we know little about. We now want to understand how the telomere-toxin is secreted and also understand how this ‘telocin’ wheedles its way into unsuspecting bacterial neighbors”

Telomere bacteriophages are widespread and equip their bacterial hosts with potent interbacterial weapons

Klebsiella host strains infected with telomere phages can grow to be the dominant lineage in mixed populations.

Many recent viral outbreaks, including SARS-CoV-2 and mpox, feature oral symptoms. A Review in Nature Reviews Immunology discusses antiviral immunity in the oral cavity and presents current mouse models for the study of oral viral infections. �’ https://go.nature.com/49xJlwg

This is figure 2, which shows that the salivary glands are important for immune defence.
