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 ... -
Evidence for a role of GABAergic and glutamatergic signalling in the basolateral amygdala in endocannabinoid-mediated fear-conditioned analgesia in rats
Rea, Kieran; Olango, Weredeselam M.; Harhen, Brendan; Kerr, Daniel M.; Galligan, Rachel; Fitzgerald, Sean; Moore, Maeve; Roche, Michelle; Finn, David P. (Elsevier, 2012-12-31)The basolateral amygdala (BLA) is a key substrate facilitating the expression of fear-conditioned analgesia (FCA). However, the neurochemical mechanisms in the BLA which mediate this potent suppression of pain responding ... -
Genotype-dependent responsivity to inflammatory pain: A role for TRPV1 in the periaqueductal grey
Madasu, Manish K.; Okine, Bright N.; Olango, Weredeselam M.; Rea, Kieran; Lenihan, Róisín; Roche, Michelle; Finn, David P. (Elsevier, 2016-08-09)Negative affective state has a significant impact on pain, and genetic background is an important moderating influence on this interaction. The Wistar-Kyoto (WKY) inbred rat strain exhibits a stress-hyperresponsive, ... -
Impaired endocannabinoid signalling in the rostral ventromedial medulla underpins genotype-dependent hyper-responsivity to noxious stimuli
Rea, Kieran; Olango, Weredeselam M.; Okine, Bright N.; Madasu, Manish K.; McGuire, Iseult C.; Coyle, Kathleen; Harhen, Brendan; Roche, Michelle; Finn, David P. (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 ... -
Repeated forced swim stress differentially affects formalin-evoked nociceptive behaviour and the endocannabinoid system in stress normo-responsive and stress hyper-responsive rat strains
Jennings, Elaine M.; Okine, Bright N.; Olango, Weredeselam M.; Roche, Michelle; Finn, David P. (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 ...
