Our latest preprint continues our investigations into spinal mechanisms of human chronic pain! We find no evidence for a loss of neurons in the dorsal horn of donors with chronic lower limb pain, and the ratio of excitatory to inhibitory interneurons also remains consistent between pain states.

The latest work from our PRECISION Human Pain Center project is now up on @biorxivpreprint.bsky.social led by Katherin Gabriel and @oliviadavis.bsky.social with a huge contribution from @allanhpool.bsky.social's lab and, of course, the Southwest Transplant Alliance: www.biorxiv.org/content/10.1...

A molecular map of the human spinal dorsal and ventral horn defines arrangement of neuronal types and glial sex differences
The spinal cord is the gateway for sensory information from the body as it ascends to the brain, as well as a major motor output center of the nervous system. It is also a key location for sensory-mot...

Thrilled to share our latest preprint using single nuq sequencing and Xenium to define neuron organisation and sex differences in glia within human spinal cord. Truly a collaborative effort, with a big shoutout to Katherin Gabriel and @tedpricethepainguy.bsky.social www.biorxiv.org/content/10.1...

Sharing a figure from our recent paper showing excitatory synapses in the human spinal dorsal horn. I’ll never get over the awe of seeing these tiny dots, which underly such an important part of the human experience! @tedpricethepainguy.bsky.social onlinelibrary.wiley.com/doi/10.1002/...

Our paper showing decreased KCC2 expression in the human spinal cord in people who died with a history of neuropathic pain is now published in PAIN: journals.lww.com/pain/abstrac... Great work from @oliviadavis.bsky.social and the teams of the De Koninck and Hildebrand labs. ❤️ 🇨🇦 collabs!

Decreased KCC2 expression in the human spinal dorsal horn... : PAIN
date there is no evidence supporting or opposing this hypothesis in humans. Here, we demonstrate that KCC2 expression is decreased in superficial dorsal horn neurons of organ donors who died with a do...

Decreased KCC2 expression in the human spinal dorsal horn associated with chronic pain and long-term opioid use
Loss of GABAergic and glycinergic inhibitory efficacy in the spinal dorsal horn is associated with neuropathic pain and opioid-induced hyperalgesia in rodent models. Downregulation of the KCC2 chlorid...
