Host AAA-ATPase VCP/p97 lyses ubiquitinated intracellular bacteria as an innate antimicrobial defence - Nature Microbiology Host AAA-ATPase VCP/p97 binds and extracts ubiquitinated proteins from the bacterial cell membrane causing bacterial lysis and death to confer cell-autonomous protection against infection.

Human giant GTPase GVIN1 forms an antimicrobial coatomer around the intracellular bacterial pathogen Burkholderia thailandensis Several human pathogens exploit the kinetic forces generated by polymerizing actin to power their intracellular motility. Human cell-autonomous immune responses activated by the cytokine interferon-ga...

Exciting work from neighbor Jörn Coers at Duke identifying a new class of host defense GTPases. Out of a genetic screen they identify the human Giant GTPase GVIN1 (previously annotated as a human pseudogene) in coatomer-based restriction of Burkholderia motility. 1808 aas long!

Glad the NHS pulled all the stops out for you! Hope you're ok and get better soon

Cell-autonomous innate immunity by proteasome-derived defence peptides - Nature Proteasomal degradation of cellular proteins generate defence peptides constitutively and in response to bacterial infection. Such peptides might provide a source of natural antibiotics that...

Fantastic new paper out @nature.com! @merbllab.bsky.social discovers proteasome-derived peptides that function as a defence against bacterial infections. I'm not an immunologist but even I can tell that this finding has huge implications for new therapeutic interventions!

Interrogating the genus Yersinia to define the rules of lipopolysaccharide lipid A structure associated with pathogenicity. Pathogen recognition by the immune system relies on germline-encoded pathogen recognition receptors which identify conserved pathogen-associated molecular patterns (PAMPs) such as the lipid A section ...

Delighted to share our last pre print -this one close to my heart- We set to define the rules of lipid A associated with virulence by interrogating the genus Yersinia. www.biorxiv.org/content/10.1...

100+ years of phase variation: the premier bacterial bet-hedging phenomenon Stochastic, reversible switches in the expression of Salmonella flagella variants were first described by Andrewes in 1922. Termed phase variation (PV), subsequent research found that this phenomenon ...
