Maternal deprivation is associated with sex-dependent alterations in nociceptive behavior and neuroinflammatory mediators in the rat following peripheral nerve injury
(Elsevier, 2013-10)
Early-life stress is associated with an increased risk of developing affective disorders and chronic pain conditions. This study examined the effect of maternal deprivation (MD) on nociceptive responding prior to and ...
Altered neuropathic pain behaviour in a rat model of depression is associated with changes in inflammatory gene expression in the amygdala
(Wiley, 2013-08-29)
The association between chronic pain and depression is widely recognized, the comorbidity of which leads to a heavier disease burden, increased disability and poor treatment response. This study examined nociceptive ...
Circuitry underlying regulation of the serotonergic system by swim stress
(Society for Neuroscience, 2003-02-01)
The dorsal raphe nucleus (DR)–serotonin (5-HT) system has been implicated in depression and is dramatically affected by swim stress, an animal model with predictive value for antidepressants. Accumulating evidence implicates ...
Chronic administration of amitriptyline differentially alters neuropathic pain-related behaviour in the presence and absence of a depressive-like phenotype
(Elsevier, 2015-02)
Chronic pain and depression share a complex, reciprocal relationship. Furthermore, in addition to treating depression, antidepressants such as amitriptyline are a first-line treatment for chronic pain conditions, indicating ...
Neuroinflammatory mechanisms linking pain and depression
(Karger, 2015)
Depression and chronic pain have been estimated to co-occur in up to 80% of patients suffering from these disorders, with this co-morbidity being more disabling and more expensive to both patients and society than either ...
Anandamide modulation of endotoxin-induced inflammation
(OMICS International, 2013-12-20)
The endocannabinoid system is comprised of the CB1
and CB2
receptors, the naturally occurring endogenous ligands, anandamide
(AEA) and 2-arachidonyl glycerol (2-AG); and the enzymes
involved in their synthesis and ...
Supraspinal modulation of pain by cannabinoids: the role of GABA and glutamate
(2007)
Recent physiological, pharmacological and anatomical studies provide evidence that one of the main roles of the endocannabinoid system in the brain is the regulation of ¿-aminobutyric acid (GABA) and glutamate release. ...
Pharmacological inhibition of monoacylglycerol lipase attenuates LPS-induced increases in cytokine expression in the rat frontal cortex and plasma: differential mechanisms of action
(2013)
Background and purpose: This study determined the effect of JZL184, a selective inhibitor of monoacylglycerol lipase (MAGL), the enzyme which preferentially catabolises the endocannabinoid 2-arachidonoyl glycerol (2-AG), ...
The endocannabinoid system in the rat dorsolateral periaqueductal grey mediates fear-conditioned analgesia and controls fear expression in the presence of nocicpetive tone
(Wiley, 2011)
Background and purpose: Endocannabinoids in the midbrain periaqueductal grey (PAG) are involved in modulating nociception and unconditioned stress-induced analgesia, however, their role in fear-conditioned analgesia (FCA) ...
Fear-induced suppression of nociceptive behaviour and activation of signal transduction molecules in the rat periaqueductal grey: role of fatty acid amide hydrolase.
(Sage, 2011-09-17)
The endocannabinoid system regulates nociception and aversion and mediates fear-conditioned analgesia (FCA). We investigated the effects of the fatty acid amide hydrolase (FAAH) inhibitor URB597, which inhibits the catabolism ...
