When they examined the tissue, they found that small neural offshoots had grown from structures called dendrites (branched projections at the end of neurons) in the dorsal horn.
It also reported that PDGF expressed in dorsal horn neurons contributes to neuropathic pain after nerve injury, (22) though how PDGF produces pain hypersensitivity remains unknown.
We found that p-CREB-immunoreactive staining was significantly enhanced in the ipsilateral spinal dorsal horn of SNI group compared with the sham group and normal group (Fig.
sup][12] ERK, p38, and JNK are downstream of many kinases and are activated in primary sensory neurons, dorsal horn neurons, and spinal glial cells, and contribute to neuropathic pain via transcriptional, translational, and posttranslational regulation.
The excitatory neurotransmitters in the dorsal horn are mediated by a number of neurotransmitters, including inhibitory amino acids, such as GABA and glycine, as well as neuropeptides, such as encephalin [42].

Inhibition of the pain signal will occur if other, stronger signals arrive at the dorsal horn at the same time, which is the theory behind massage therapies and transcutaneous electrical nerve stimulation (TENS).

The team then looked at the dorsal horn, the point in the spine where sensory signals are sent to the brain, to find cells that allowed the Nppb molecule to be received.
They are present in the insula, amygdala, hypothalamus, hippocampus, rostral ventromedial medulla and spinal dorsal horn.
