Rhinoviruses cause common cold & asthma attacks but are also often benign. Using nasal organoids, we learned how the community of cells in the lining the nasal passages coordinates to respond to rhinovirus and which responses lead to excess mucus & inflammation. www.cell.com/cell-press-b...

Rhinovirus triggers distinct host responses through differential engagement of epithelial innate immune signaling

Rhinoviruses are the most frequent cause of common colds and also a major cause of respiratory distress in high-risk groups. Using single-cell sequencing of rhinovirus-infected nasal epithelial organo...

Thrilled to share our new preprint showing that dietary amino acids license the NLRP3 inflammasome via mTOR-dependent mRNA translation! Congrats to co-1st authors @mikelhaggadone.bsky.social, Brian Goldspiel, co-senior author @metabailism.bsky.social & collaborators! www.biorxiv.org/content/10.6...

I’m stoked to share my postdoc work with @sunnyshinlab.bsky.social, a collaborative effort with @metabailism.bsky.social & Brian Goldspiel, aided by many valued collaborators: Environmental Amino Acid Sensing Regulates the Rate of ASC Translation and NLRP3 Inflammasome Assembly. Some big takeaways:

Check out our new publication, a collaboration with Giovanni Luchetti and Vishva Dixit @ Genentech. We show that the E.coli effector NleL inhibits intestinal epithelial cell extrusion after #inflammasome activation via degrading the kinases ROCK1 and 2!! www.nature.com/articles/s41...

The bacterial ubiquitin ligase NleL evades host defence mechanisms both by inhibiting pyroptosis and by preventing infected intestinal epithelial cells from being extruded into the lumen and expelled ...

The mechanism of STING NF-κB signaling has remained a mystery. An exciting new study from the Paludan lab now uses data throughout animal STING evolution to provide new answers – including isolating white blood cells from turtles and carp! www.nature.com/articles/s41...

STING signals to NF-κB from late endolysosomal compartments using IRF3 as an adaptor - Nature Immunology

Here the authors show how the DNA-sensing cGAS–STING pathway activates NF-κB and inflammatory gene expression with delayed kinetics via post-Golgi endolysosomal signaling.

Extra kudos and thanks to all the staff at NIH and NSF and other federal funding agencies for working extra hard in very small windows of opportunity to get grants reviewed and funds released before the attention-addled federal policies change again (on an hourly basis).
