Burke, Nikita N.; Geoghegan, E.; Moriarty, Orla; Finn, David P.; Kerr, Daniel M.; Roche, Michelle (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 ... -
Am I being watched? The role of researcher presence on toddlers’ behaviour during ‘everyday’ pain experiences: a pilot study
O'Sullivan, Grace; McGuire, Brian; Roche, Michelle; Caes, Line (Taylor & Francis, 2019-12-31)Objective: Paediatric research on 'everyday' pain experiences is sparse, stemming from a lack of appropriate methodologies. We explored the feasibility of two methodologies for conducting naturalistic observations of ... -
Anandamide modulation of endotoxin-induced inflammation
Kerr, Daniel M.; Henry, Rebecca; Roche, Michelle (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 ... -

Okine, Bright N.; Mc Laughlin, Gemma; Gaspar, Jessica C.; Harhen, Brendan; Roche, Michelle; Finn, David P. (Elsevier, 2020-07-13)The G-protein coupled receptor, GPR55, modulates nociceptive processing. Given the expression of GPR55 in the anterior cingulate cortex (ACC), a key brain region involved in the cognitive and affective dimensions of pain, ... -
Attenuation of fear‐conditioned analgesia in rats by monoacylglycerol lipase inhibition in the anterior cingulate cortex: Potential role for CB2 receptors
Corcoran, Louise; Mattimoe, Darragh; Roche, Michelle; Finn, David P. (The British Pharmacological Society, 2020-01-22)Improved understanding of brain mechanisms regulating endogenous analgesia is important from a fundamental physiological perspective and for identification of novel therapeutic strategies for pain. The endocannabinoid ... -
Brain CB2 receptors: Implication for Neuropsychiatric disorders
Roche, Michelle; Finn, David P. (2010)Although previously thought of as the peripheral cannabinoid receptor, it is now accepted that the CB2 receptor is expressed in the central nervous system on microglia, astrocytes and subpopulations of neurons. Expression ... -
Characterisation of peroxisome proliferator-activated receptor signalling in the midbrain periaqueductal grey of rats genetically prone to heightened stress, negative affect and hyperalgesia
Okine, Bright N.; Gaspar, Jessica C.; Madasu, Manish K.; Olango, Weredeselam M.; Harhen, Brendan; Roche, Michelle; Finn, David P. (Elsevier, 2016-12-01)The stress-hyperresponsive Wistar-Kyoto (WRY) rat strain exhibits a hyperalgesic phenotype and is a useful genetic model for studying stress-pain interactions. Peroxisome proliferator-activated receptor (PPAR) signalling ... -
Characterization of the affective component of acute postoperative pain associated with a novel rat model of inguinal hernia repair pain
Bree, Dara; Moriarty, Orla; Broom, Daniel C.; Kelly, John P.; Roche, Michelle; Finn, David P. (Wiley, 2015-12-10)Aims: Acute postoperative pain remains a significant healthcare issue. Historically, the assessment of postoperative pain in rodents has relied on evoked withdrawal or reflexive measures. Using a recently developed, ... -
Chronic administration of amitriptyline differentially alters neuropathic pain-related behaviour in the presence and absence of a depressive-like phenotype
Burke, Nikita N.; Finn, David P.; Roche, Michelle (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 ... -
Chronic administration of buprenorphine in combination with samidorphan produces sustained effects in olfactory bulbectomised rats and Wistar-Kyoto rats
Burke, Nikita N.; Li, Yan; Daniel R Deaver, Daniel R.; Deaver, Daniel R.; Finn, David P.; Roche, Michelle; Eyerman, David J.; Sanchez, Connie; Kelly, John P.
