Gabapentin has been an effective medication for many people living with pain. It is particularly helpful for neuropathic pain when used thoughtfully.

Shaping the Action Potential in Dorsal Root and Trigeminal Ganglia Neurons: Relevance to Pain Mechanisms Sensory neurons of the dorsal root ganglia (DRG) and trigeminal ganglia (TG) are critical for transmitting somatosensory information, including pain, to the central nervous system. In these neurons, a...

Potential role for immune cell signatures as predictors of acute and chronic pain in adolescents post major musculoskeletal surgery - PubMed Our findings suggest that immune cell signatures are potentially useful as biomarkers, prognostic indicators, and guides for personalized surgical recovery in youth.

Very nice recent study from the Chidambaran Lab in our dept @cincychildrens.bsky.social suggesting potential immune cell signatures in acute vs chronic post-surgical pain #PainResearch pubmed.ncbi.nlm.nih.gov/41077098/

Physiological actions of a humanized P2X4 scFv on peripheral and central neurons in male mice with neuropathic pain Neuropathic pain remains a challenging clinical condition due to its resistance to conventional analgesics. The purinergic P2X4 receptor (P2X4R), an A…

Our final contribution to this collaboration is now online. We obtained electrophysiological recordings of DRG/TG neurons and Fos+ neurons of spinal dorsal horn & vlPAG in 2 models of neuropathic pain to study the actions of a humanized P2X4R scFv #PainResearch www.sciencedirect.com/science/arti...

Three lab members standing proudly in front of a newly assembled electrophysiology rig. The setup includes a micromanipulator, amplifier, and monitor, with cables neatly arranged. Everyone is smiling in casual lab attire, celebrating the milestone in a well-lit lab space.

📸 Big day in the lab!
Our new electrophysiology rig is officially up and running — huge thanks to everyone who helped make this happen. Excited for the science ahead! 🧠⚡️

Anti-CV2/CRMP5 autoantibodies as drivers of sensory neuron excitability and pain in rats - Nature Communications Lung and thymoma cancer patients often suffer from autoimmunity and related painful neuropathies. Here the authors show that patient-derived anti-CRMP5 autoantibody binds to rat dorsal root ganglia to...

I’m proud to share that our first paper from the lab has just been published in Nature Communications: www.nature.com/articles/s41...
This work uncovers a mechanism by which autoantibodies targeting CRMP5 contribute to neuropathic pain in paraneoplastic syndromes.
