1st paper from Sadler Lab is out!! Highlights: 1) A. muciniphila reverses sickle cell (SCD) pain, 2) fecal transplant from SCD mice induces pain via bilirubin-TRPM2 vagal signaling, 3) BilR+ bacteria less abundant in SCD patient poo, 4) RNAseq on HUMAN nodose ganglia! www.cell.com/cell-host-mi...
Gut microbiota and metabolites drive chronic sickle cell disease pain in mice
Brandow et al. describe how the gut microbiome drives chronic sickle cell disease (SCD) pain. SCD guts contain excessive heme catabolites, fewer bacteria that metabolize bilirubin, and low levels of A...

New method development work from our lab that I hope will make it easier for labs to work with peripheral nervous system tissues recovered from organ donors, tissue donors, and fast autopsies: www.biorxiv.org/content/10.1... This work was led by the amazing duo of Joe Lesnak and Mandee Schaub

BOOM! Cool to see the final form of this great work now published. Deep new insight into human peripheral neuropathy. Congrats @mheming.bsky.social and colleagues on a great study.

Very proud that our human PNS atlas is finally published in @natcomms.nature.com We found perineurial hyperplasia and lipid-associated nerve macrophages in #polyneuropathies.

CRMP2 expression and function is already validated in human lymphocytes from patients with HTLV1 and MS. Which brings a lot of translational relevance to this manuscript. It's all very exciting

A big game changer in the CRMP2 game bringing together old and new litterature and further validating CRMP2 phosphorylation at S522 as a excellent therapeutic target for alleviating pain.

Jiang et al. find that collapsin response mediator protein 2 phosphorylation in CD4+ T cells affects spinal infiltration and pain modulation, hinting at novel therapies for rheumatoid arthritis–related chronic pain. Learn more in #PAIN bit.ly/3HnqDO4

We started with an observation from the clinic but ended with a model, a mechanism, and a path toward treatment.

Science is at its best when it closes the loop—from bench to bedside, and back again.

We’re proud of what this work uncovered—but even more excited about what it unlocks next!

I am grateful to all co-authors for their input and support.

This project was supported by funds from NINDS, The University of Arizona and Saint Louis University. Thanks to our funders for supporting high-risk, translational work.

Lyuba Salih & Nicolas Dumaire at SLU took time off from their graduate projects to help close key experiments.

Jérôme Honnorat provided invaluable clinical insight and precious patient sera.

This project began with Rajesh Khanna, whose mentorship and support made the finish line possible.

This was a true team effort:

Laurent Martin and Harrison Stratton contributed greatly with behavior, electrphysiology, critical discussions and key ideas that helped to transform dream experiments into figures.

This project took us beyond our scientific comfort zone and into a highly translational adventure.
We worked with human samples and ran studies designed to directly inform patient care. In doing so, we built a framework to rapidly uncover how CRMP5 autoantibodies cause pain—and how to stop it.
aubinmoutal.bsky.social
We then created a DNA immunization model that replicated CRMP5 autoimmunity and pain in rats.

this led us to:
- Evaluate the therapeutic potential of clinically available pain relieving drugs
- Use anti-CD20 (Rituximab, B cell depletion) to reverse behavior and hyperexcitability long term.
aubinmoutal.bsky.social
We show that patient-derived anti-CRMP5 autoantibodies:
🔹 Penetrate DRG neurons and bind intracellular CRMP5
🔹 Induce hyperexcitability in DRG neurons
🔹 Cause mechanical hypersensitivity in rats

Depleting antibodies or masking their epitopes blocks these effects.

Pain is a frequent yet poorly understood symptom in paraneoplastic neurological syndromes. We started from clinical reports of ~80% of patients with anti-CV2/CRMP5 autoantibodies having a painful neuropathy, but the mechanisms remained unknown.
