5.35 – Ascending pathways: Anatomy and physiology
Publication year: 2008

Abstract/Results: ABSTRACT:
Nociceptive information traveling from the periphery in primary sensory neurons is transmitted to second-order neurons located at the spinal cord and cranial sensory nuclei. From this first relay, various pathways distribute nociceptive input through higher processing centers, so that pain is ultimately perceived in its multiple dimensions and adequate adaptive responses are generated. Although these ascending pathways are believed to terminate in the cortex with one or several relay stations in their way, the term ‘nociceptive ascending pathways’ is normally used in a restricted sense to designate the neuronal tracts that connect the spinal cord with supraspinal regions, each pathway being named from the brain area at which it terminates. About 20 nociceptive ascending pathways have been uncovered so far, which terminate at multiple sites, from the upper spinal cord up to the thelencephalon.
There are subtle differences between the various pathways as to the laminar location and morphology of the spinal neurons of origin, although the latter aspect has been addressed only sporadically. Data on the spinal location of the ascending tracts point to the lack of clear segregation in their way to the brain. As to their neurochemical architecture, our present knowledge is still scarce and thus far from allowing a neurochemical-based pathway characterization. The data collected on the response properties of the neurons of origin of most pathways do not reveal major differences between them. High-threshold, wide-dynamic-range, and low-threshold neurons always participate albeit in different proportions, and, whenever investigated, inputs from skin, viscera, and deep tissues converge onto the same pathway.
The multitude of ascending nociceptive pathways, together with the subtleness of the anatomical and physiological aspects that separate them as to their origin at the spinal cord, makes difficult to attribute a particular functional meaning to each one. A tentative way of unraveling the role of each pathway in nociceptive processing has been the elucidation of the connections established by the target. There is, however, a fundamental need to further investigate the functional specificity of each pathway and in which way the compound organization of the nociceptive system contributes to the processing of the various pain states.

From neuroanatomy to gene therapy: Searching for new ways to manipulate the supraspinal endogenous pain modulatory system
Publication year: 2007
URL:
http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2375764/pdf/joa0211-0261.pdf
Abstract/Results: ABSTRACT:
The endogenous pain modulatory system is a complex network of brain areas that control nociceptive transmission at the spinal cord by inhibitory and facilitatory actions. The balance between these actions ensures effective modulation of acute pain, while during chronic pain the pronociceptive effects appear to prevail. The mechanisms underlying this imbalance were studied as to the role of two medullary components of the pain modulatory system: the dorsal reticular nucleus and the caudal ventrolateral medulla, which function primarily as pronociceptive and antinociceptive centres, respectively. Both areas are connected with the spinal dorsal horn by closed reciprocal loops. In the spino-dorsal reticular nucleus loop, the ascending branch is strongly inhibited by spinal GABAergic neurons, which may act as a buffering system of the dorsal reticular nucleus-centred amplifying effect. In the spino-caudal ventrolateral medulla loop, the ascending branch is under potent excitation of substance P (SP) released from primary afferents, which is likely to trigger the intense descending inhibition detected in acute pain. During chronic pain, the activity in the lateral reticular formation of the caudal ventrolateral medulla changes, so that the action of the caudal ventrolateral medulla upon SP-responsive spinal neurons shifts from inhibitory to excitatory. The mechanisms of this modulatory shift are unknown but probably relate to the decresed expression of µ-opioid, d-opioid and GABAB receptors. Normalizing receptor expression in the caudal ventrolateral medulla or controlling noci-evoked activity at the dorsal reticular nucleus or caudal ventrolateral medulla by interfering with neurotransmitter release is now possible by the use of gene therapy, an approach that stands out as a unique tool to manipulate the supraspinal endogenous pain control system.

Dynamic of migration of HSV-1 from a medullary pronociceptive centre: antinociception by overexpression of the preproenkephalin transgene

Abstract/Results: ABSTRACT:
Herpes Simplex Virus type 1 (HSV-1) vectors are known to inhibit nociceptive transmission at the spinal cord after peripheral applications. Similar approaches may also be useful when applied at the supraspinal pain control system as the system includes pronociceptive (facilitatory) components. We performed a study aimed to analyse the migration of HSV-1 along with the inhibition of pronociception from the medullary dorsal reticular nucleus (DRt), a major facilitatory component of the supraspinal pain control system. To study the migration, a HSV-1 vector expressing lacZ under control of the human cytomegalovirus (hCMV) promoter was injected in the DRt and the expression of ß-galactosidase (ß-gal) was detected at 2, 4, 7, 10 and 14 days. Numerous ß-gal-immunoreactive neurons were observed at the injection site until day 4, and at some of the brain areas projecting to the DRt until day 7. To block the pronociceptive effects of the DRt, a HSV-1 vector expressing the preproenkephalin transgene, under the control of hCMV promoter, was injected into the DRt. Behavioural evaluation was performed at the time-points referred above, using the paw withdrawal latency test to evaluate thermal nociceptive responses. Anti-hyperalgesic effects persisted during 4 days, decreasing after that time-point. The present study demonstrates that selective migration of HSV-1 should be considered in gene therapy strategies based on HSV-1 injections into the brain. The study also shows that it is possible to decrease pain facilitation from the brain using opioidergic inhibition of pronociceptive supraspinal areas.

Participation of µ-opioid, GABAB, and NK1 receptors of major pain control medullary areas in pathways targeting the rat spinal cord: Implications for descending modulation of nociceptive transmission
Publication year: 2008
URL:
http://onlinelibrary.wiley.com/doi/10.1002/cne.21793/abstract
Abstract/Results: ABSTRACT:
Several brain areas modulate pain transmission through direct projections to the spinal cord. The descending modulation is exerted by neurotransmitters acting both at spinally projecting neurons and at interneurons that target the projection neurons. We analyzed the expression of µ-opioid (MOR), ?-aminobutyric acid GABAB, and NK1 receptors in spinally projecting neurons of major medullary pain control areas of the rat: rostroventromedial medulla (RVM), dorsal reticular nucleus (DRt), nucleus of the solitary tract, ventral reticular nucleus, and lateralmost part of the caudal ventrolateral medulla. The retrograde tracer cholera toxin subunit B (CTb) was injected into the spinal dorsal horn, and medullary sections were processed by double immunocytochemistry for CTb and each receptor. The RVM contained the majority of double-labeled neurons followed by the DRt. In general, high percentages of MOR- and NK1-expressing neurons were retrogradely labeled, whereas GABAB receptors were mainly expressed in neurons that were not labeled from the cord. The results suggest that MOR and NK1 receptors play an important role in direct and indirect control of descending modulation. The co-localization of MOR and GABAB in DRt neurons also demonstrated by the present study suggests that the pronociceptive effects of this nucleus may be controlled by local opoidergic and GABAergic inhibition of the pronociception increased during chronic pain
