Nociceptive behaviours evoked by intrathecal (R, S)-3,5-dihydroxyphenylglycine to rats with neuropathic and inflammatory pain conditionsDuckworth, Phoebe E. January 2006 (has links)
Spontaneous nociceptive behaviours (SNBs) are an important but under-studied component of chronic pain conditions. The group I metabotropic glutamate receptor (mGluR) agonist DHPG produces SNBs when injected intrathecally and group I mGluR antagonists are effective at reducing symptoms of neuropathic and inflammatory pain. The present experiments tested whether rats with sciatic nerve injury or persistent inflammation exhibit greater SNBs following intrathecal DHPG compared with control animals. SNBs were observed following intrathecal injection of DHPG between the L4 and L5 vertebrae. When DHPG was injected in rats with chronic constriction injury (CCI) of the sciatic nerve, they showed increased paw stamping behaviour compared to DHPG-injected sham controls. Results of the complementary experiment in rats with complete Freund's adjuvant (CFA)-induced inflammation did not show significant effects. Both CCI and CFA rats injected with DHPG showed increased paw licking and biting behaviour in the ipsilateral paws. These results provide evidence for behaviourally relevant contributions of group I mGluRs to SNBs in models of neuropathic and inflammatory pain.

Positional cloning of genes contributing to variability in nociceptive and analgesic phenotypesSmith, Shad Benjamin. January 2006 (has links)
Variability between individuals in pain and analgesia phenotypes is often observed in both clinical and experimental settings. The source of this variability has long been attributed to the interplay of environmental and genetic factors, but we have only recently begun identifying these determinants. Experiments comparing isogenic strains of mice have suggested that different pain tests may share a genetic basis; likewise, analgesic magnitude induced by disparate drug classes may be influenced by a common set of genes. / We have presently used a quantitative trait locus mapping strategy to search for genes responsible for variability in analgesic response to five analgesic drugs (the opioids morphine and U50,488, and the non-opioid drugs clonidine, epibatidine, and WIN55,212-2). We first used a B6129PF2 intercross population to map sensitivity to clonidine, morphine, and WIN55,212-2 to a 30 cM region on distal Chromosome 1. In silico and congenic strain mapping techniques allowed us to refine this linkage, as well as generalize it to four of the five drugs and seven mouse strains. Kcnj9 (GIRK3) was identified as a likely candidate gene underlying response to multiple analgesic modalities. We showed that this gene is differentially expressed between C57BL/6 and 129P3 strains in the periaqueductal gray. We also determined that Kcnj9 null mutant mice exhibit attenuated analgesic responses. / We previously mapped nociceptive response to the formalin test to two loci on Chr. 9 and 10 using an AB6F2 cross. Using in silico mapping, we identified several haplotypes near the Atp1b3 gene on Chr. 9 (a subunit of the sodium-potassium pump) that correlated highly with early phase formalin response. We then showed that pharmacological antagonism of the sodium-potassium channel eliminates the strain difference observed between A and C57BL/6 mice, supporting a role for this gene in determining response to formalin. Positional cloning of the Chr. 10 locus, employing recombinant and congenic strains, allowed us to refine the location of the locus to a <3 cM interval. A small number of genes in this region were identified as differentially expressed by microarray analysis, providing a short list of candidate genes for follow-up investigation.
