Impaired cued and spatial learning performance and altered cannabinoid CB1 receptor functionality in the substantia nigra in a rat model of diabetic neuropathy
(Elsevier, 2016-01-13)Diabetes, and associated diabetic neuropathic pain, impact negatively on cognitive function. However, the underlying mechanisms remain poorly understood. This study investigated neuropathic pain-related behaviour and ... -
Impaired endocannabinoid signalling in the rostral ventromedial medulla underpins genotype-dependent hyper-responsivity to noxious stimuli
(International Association for the Study of Pain, 2014-01)Pain is both a sensory and an emotional experience, and is subject to modulation by a number of factors including genetic background modulating stress/affect. The Wistar-Kyoto (WKY) rat exhibits a stress-hyper-responsive ... -
Impaired recognition memory and cognitive flexibility in the rat L5-L6 spinal nerve ligation model of neuropathic pain
(De Gruyter, 2016-01-01)Background and aims: Although neuropathic pain is known to negatively affect cognition, the neural mechanisms involved are poorly understood. Chronic pain is associated with changes in synaptic plasticity in the brain which ... -

Inhibition by Anandamide of 6-Hydroxydopamine-Induced Cell Death in PC12 Cells
(2010)6-hydroxydopamine (6-OHDA) is a selective neurotoxin that is widely used to investigate cell death and protective strategies in models of Parkinson's disease. Here, we investigated the effects of the endogenous cannabinoid, ... -
Involvement of the endocannabinoid system in attentional modulation of nociceptive behaviour in rats
(Wiley, 2014-11-15)BackgroundDistraction is used clinically to relieve and manage pain. It is hypothesized that pain demands attention and that exposure to another attention-demanding stimulus causes withdrawal of attention away from painful ... -
Locomotor and anti-immobility effects of buprenorphine in combination with the opioid receptor modulator samidorphan in rats
(Elsevier, 2018-12-13)Modulation of the opioid system has re-emerged as a potential therapeutic avenue for treating depression, with efficacy of a fixed-dose combination of buprenorphine (BUP), a partial mu-opioid receptor (MOR) agonist and ... -
Modulation of Conditioned Fear, Fear-Conditioned Analgesia, and Brain Regional C-Fos Expression Following Administration of Muscimol into the Rat Basolateral Amygdala
(Elsevier, 2011-04)Evidence suggests that gamma-aminobutyric acid (GABA) signalling in the basolateral amygdala (BLA) is involved in pain, fear, and fear-conditioned analgesia (FCA). In this study, we investigated the effects of intra-BLA ... -
Modulation of stress by imidazoline binding sites: Implications for psychiatric disorders
(Taylor & Francis, 2009-07-07)In this review, we present evidence for the involvement of imidazoline binding sites (IBS) in modulating responses to stress, through central control of monoaminergic and hypothalamo-pituitary-adrenal (HPA) axis activity. ... -
Molecular and electrophysiological changes in the prefrontal cortex-amygdala-dorsal periaqueductal grey pathway during persistent pain state and fear-conditioned analgesia
(Elsevier, 2011-10)Fear-conditioned analgesia (FCA) is the reduction in pain responding which is expressed upon re-exposure to a context previously paired with an aversive stimulus. Projections along the prefrontal cortex (PFC)¿amygdala¿dorsal ... -
N-palmitoylethanolamide in the anterior cingulate cortex attenuates inflammatory pain behaviour indirectly via a CB1 receptor-mediated mechanism
(Lippincott, Williams & Wilkins, 2016-12)The neural substrates and mechanisms mediating the antinociceptive effects of the endogenous bioactive lipid, N-palmitoylethanolamide (PEA), require further investigation. We investigated the effects of exogenous PEA ... -
Pharmacological blockade of PPAR isoforms increases conditioned fear responding in the presence of nociceptive tone
(MDPI, 2020-02-24)Peroxisome proliferator-activated receptors (PPARs) are nuclear receptors with three isoforms (PPAR¿, PPARß/¿, PPAR¿) and can regulate pain, anxiety, and cognition. However, their role in conditioned fear and pain-fear ... -
Pharmacological inhibition of endocannabinoid degradation modulates the expression of inflammatory mediators in the hypothalamus following an immunological stressor
(Elsevier, 2011-09)The endocannabinoid system is an important regulator of the nervous, neuroendocrine, and immune systems, thus representing a novel therapeutic target for stress-related neuroinflammatory and psychiatric disorders. However, ... -
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), ... -
PPARs and pain
(Wiley, 2018-04-21)Chronic pain is a common cause of disability worldwide and remains a global health and socio-economic challenge. Current analgesics are either ineffective in a significant proportion of patients with chronic pain or ... -
The prefrontal cortical endocannabinoid system modulates fear–pain interactions in a subregion‐specific manner
(Wiley, 2018-05-30)Background and Purpose The emotional processing and coordination of top‐down responses to noxious and conditioned aversive stimuli involves the medial prefrontal cortex (mPFC). Evidence suggests that subregions of the ... -
Repeated forced swim stress differentially affects formalin-evoked nociceptive behaviour and the endocannabinoid system in stress normo-responsive and stress hyper-responsive rat strains
(Elsevier, 2015-05-16)Repeated exposure to a homotypic stressor such as forced swimming enhances nociceptive responding in rats. However, the influence of genetic background on this stress-induced hyperalgesia is poorly understood. The aim of ... -
A role for the ventral hippocampal endocannabinoid system in fear-conditioned analgesia and fear responding in the presence of nociceptive tone in rats.
(Elsevier, 2011-08)The endogenous cannabinoid (endocannabinoid) system plays an important role in fear-conditioned analgesia (FCA) and expression and extinction of conditioned fear. The hippocampus has an established role in both pain and ... -
A role for viral infections in Parkinson's etiology?
(Portland Press, 2018-04-16)Despite over 200 years since its first description by James Parkinson, the cause(s) of most cases of Parkinson’s disease (PD) are yet to be elucidated. The disparity between the current understanding of PD symptomology and ... -
The role of the brain's endocannabinoid system in pain and its modulation by stress
(Elsevier, 2015-11-06)Stress has a complex, bidirectional modulatory influence on pain. Stress may either reduce (stress-induced analgesia) or exacerbate (stress-induced hyperalgesia) pain depending on the nature, duration, and intensity of the ...
