The nociceptor neurons and non-nociceptor somatosensory neurons have cell body located in the dorsal root ganglia in common.
What are nociceptor neurons and non-nociceptor somatosensory neurons?
- Nociceptors are a specialized subset of sensory neurons that mediate pain and densely innervate peripheral tissues including the skin, joints, respiratory, and gastrointestinal tract.
- Various subsets of nociceptors exist, and can respond to mechanical, chemical or thermal noxious stimuli.
- Nociceptor sensory neurons protect organisms from dangers by eliciting pain and driving avoidance.
- Pain also accompanies many types of inflammation and injury.
- Active crosstalk occurs between nociceptor neurons and the immune system to regulate pain, host defence, and inflammatory diseases. Immune cells at peripheral nerve terminals and within the spinal cord release mediators that modulate mechanical and thermal sensitivity.
- In turn, nociceptor neurons release neuropeptides and neurotransmitters from nerve terminals that regulate vascular, innate, and adaptive immune cell responses.
- In contrast to the scenario of nociceptive pain described above, that these forms of pathological pain often occur as the direct result of non-nociceptive afferent activity.
- The evidence also suggests that this "non-nociceptive pain" is dependent upon changes in central neuronal processes which occur as the result of prior or ongoing nociception or as the result of any of several neuropathological processes.
