Neuropathic pain is one of the most important types of chronic pain. It is caused by neuronal damage. Clinical and experimental studies suggest a critical role for neuro-immune interactions in the development of neuropathic pain. Herein, we have shown that the cytoplasmic receptor Nod-like receptor-2, NOD2, and its adaptor-signaling molecule RIPK2, participate in the development of neuropathic pain after peripheral nerve injury (Spared nerve injury model). The activation of NOD2 signaling in peripheral macrophage mediates the development of neuropathic pain through the production of pro-nociceptive cytokines (TNF and IL-1β). This study found that peripheral nerve injury promoted a systemic increase in the NOD2 ligand. These results highlight a previously undetermined role for NOD2 signaling in the development of neuropathic pain, suggesting a new potential target for preventing neuropathic pain.

A NOD signaling adaptor protein that contains two C-terminal leucine-rich domains which recognize bacterial PEPTIDOGLYCAN. It signals via an N-terminal capase recruitment domain that interacts with other CARD SIGNALING ADAPTOR PROTEINS such as RIP SERINE-THEONINE KINASES. The protein plays a role in the host defense response by signaling the activation of CASPASES and the MAP KINASE SIGNALING SYSTEM. Mutations of the gene encoding the nucleotide oligomerization domain 2 protein have been associated with increased susceptibility to CROHN DISEASE.
Disorder of the peripheral nerves that primarily impair small nerve fibers. The affected small nerve fibers include myelinated A-delta fibers (see A FIBERS) and unmyelinated C FIBERS. Because these small fibers innervate skin and help control autonomic function, their neuropathy presents with neuropathic pain, reduced thermal and pain sensitivity, and autonomic dysfunction (e.g. abnormal sweating or facial flushing). Small fiber neuropathy can be idiopathic or associated with underlying diseases (e.g., AMYLOIDOSIS; DIABETES MELLITUS; SARCOIDOSIS; or VASCULITIS).
A purinergic P2X neurotransmitter receptor involved in sensory signaling of TASTE PERCEPTION, chemoreception, visceral distension, and NEUROPATHIC PAIN. The receptor comprises three P2X3 subunits. The P2X3 subunits are also associated with P2X2 RECEPTOR subunits in a heterotrimeric receptor variant.

The P2X2 subunits also have been found associated with P2X3 RECEPTOR subunits in a heterotrimeric receptor variant.
A widely distributed purinergic P2X receptor subtype that plays a role in pain sensation. P2X4 receptors found on MICROGLIA cells may also play a role in the mediation of allodynia-related NEUROPATHIC PAIN.
