The first paper from the Crewe lab is online today. We found that macrophage-meditated clearance of EVs is a major determinate of circulating adipocyte EV levels. This clearance is disrupted in obesity. A huge effort by Snigdha Tiash!

Big congrats to @MargueriteMrad for winning the Outstanding Poster Award in basic science at Diabetes Day Symposium at @WashUMedEndo for presenting her work on immune-progenitor crosstalk in adipose tissue!
[please retweet] I’m #hiring! The Millman Lab is looking for a postdoctoral researcher to lead an exciting new project focused on vascularized #stemcell-derived islets for #diabetes disease modeling and cell replacement therapy. Email me your CV and cover letter.
I'm happy to present our new web-tool CORESH https://t.co/r1bswFuZXo for searching public gene expression datasets using gene signature as a query, developed by @vd_sukhov, which was just published in @NAR_open https://t.co/PdDMgQz56a 1/n

ITACONATE MECHANISM SOLVED!!
Tom Paulenda @tompaulenda solved molecular mechanism of immunoregulatory action of itaconate in macrophages:
https://t.co/efeSAW4ZTA
Previously, our lab has discovered two major immunoregulatory phenotypes of itaconate in macrophages - enhancement of type I interferon signaling and inhibition of late inflammasome activation (Swain et al, 2020 and Bambouskova et al, 2021). Yet the mechanism of immunoregulation itaconate has been elusive even though we (and others) have previously shown its ability to inhibit Sdh and its mild electrophilic properties.
In the latest work, we believe we have finally cracked that puzzle!!
We show that both immunoregulatory phenotypes are driven by the ability of itaconate to modulate ROS through non-covalent inhibition of the peroxiredoxin 5, mitochondrial peroxide-detoxifying enzyme.
We describe major new phenotypes for the pro-interferon action of itaconate in vitro and in vivo and show that Prdx5 inhibiton is sufficient for immunoregulatory action of itaconate and does not require neither Sdh inhibition nor its mild
electrophilicity.

Honored and excited to receive the 2025-2026 CTRFP Award! 🎉 Grateful for the support as we continue exploring links between metabolism and autoimmunity.
If you have a sec, check out our new paper by @Amy_Hsu_ with @HibbsLab (@MonashImmunol) and @ivana_hal (@imgprague) showing that CD53 drives cellular infiltration and inflammation in allergic airway asthma-like disease in @AllergyEaaci (it's a quick read). https://t.co/CLV7l8eKJu
Collaborative work of @slavicaPD, @Hashemyaser4, Jovanovic Lab and @DjuranovicLab - a new method to isolate ribosomes and translational material in minutes. We show multiple usage of our RAPPL method in biochemical and structural assays with ribosomes. Please be free to contact us for further instructions if needed. @IsraelF96135088 you'll like this one.

Thrilled and grateful to receive this year's Discovery Grant from @NPF! 🎉 Excited to explore how dysregulated metabolism contributes to psoriasis pathology. Looking forward to the discoveries ahead!
Very excited to share our latest paper out today
