Neural correlates of hyperalgesia in the monosodium iodoacetate model of osteoarthritis pain (2016)
Journal Article
Abaei, M., Sagar, D. R., Stockley, E. G., Spicer, C. H., Prior, M., Chapman, V., & Auer, D. P. (in press). Neural correlates of hyperalgesia in the monosodium iodoacetate model of osteoarthritis pain. Molecular Pain, 12, https://doi.org/10.1177/1744806916642445

Background: The mechanisms driving osteoarthritic pain remain poorly understood, but there is increasing evidence for a role of the central nervous system in the chronification of pain.We used functional magnetic resonance imaging to investigate the...

Blocking the tropomyosin receptor kinase A (TrkA) receptor inhibits pain behaviour in two rat models of osteoarthritis (2015)
Journal Article
Nwosu, L. N., Mapp, P. I., Chapman, V., & Walsh, D. A. (in press). Blocking the tropomyosin receptor kinase A (TrkA) receptor inhibits pain behaviour in two rat models of osteoarthritis. Annals of the Rheumatic Diseases, 75(6), https://doi.org/10.1136/annrheumdis-2014-207203

Objectives: Tropomyosin receptor kinase A (TrkA) mediates nociceptor sensitisation by nerve growth factor (NGF), but it is unknown whether selective TrkA inhibition will be an effective strategy for treating osteoarthritis (OA) pain. We determined th... Read More about Blocking the tropomyosin receptor kinase A (TrkA) receptor inhibits pain behaviour in two rat models of osteoarthritis.

A., & Constantinescu, C. S. (2015). Effects of pro-inflammatory cytokines on cannabinoid CB1 and CB2 receptors in immune cells. Acta Physiologica, 214(1), 63-74. https://doi.org/10.1111/apha.12474

© 2015 The Authors. Aims: To investigate the regulation of cannabinoid receptors CB1 and CB2 on immune cells by pro-inflammatory cytokines and its potential relevance to the inflammatory neurological disease, multiple sclerosis (MS). CB1 and CB2 sign... Read More about Effects of pro-inflammatory cytokines on cannabinoid CB1 and CB2 receptors in immune cells.

Calcitonin gene-related peptide-expressing sensory neurons and spinal microglial reactivity contribute to pain states in collagen-induced arthritis (2015)
Journal Article
Nieto, F. R., Clark, A. K., Grist, J., Chapman, V., & Malcangio, M. (2015). Calcitonin gene-related peptide-expressing sensory neurons and spinal microglial reactivity contribute to pain states in collagen-induced arthritis. Arthritis and Rheumatology, 67(6), https://doi.org/10.1002/art.39082

Objective

To evaluate the contribution of sensory neurons in ankle joints and adjacent tissue to the development of pain in collagen‐induced arthritis (CIA), and to determine the relationship between pain and the appearance of clinical signs....

Dissecting the contribution of knee joint NGF to spinal nociceptive sensitization in a model of OA pain in the rat (2015)
Journal Article
Sagar, D. R., Nwosu, L. N., Walsh, D. A., & Chapman, V. (2015). Dissecting the contribution of knee joint NGF to spinal nociceptive sensitization in a model of OA pain in the rat. Osteoarthritis and Cartilage, 23(6), https://doi.org/10.1016/j.joca.2015.01.010

Objective: Although analgesic approaches targeting nerve growth factor (NGF) for the treatment of osteoarthritis (OA) pain remain of clinical interest, neurophysiological mechanisms by which NGF contribute to OA pain remain unclear. We investigated t... Read More about Dissecting the contribution of knee joint NGF to spinal nociceptive sensitization in a model of OA pain in the rat.

Simultaneous tissue profiling of eicosanoid and endocannabinoid lipid families in a rat model of osteoarthritis (2014)
Journal Article
Wong, A., Sagar, D. R., Ortori, C. A., Kendall, D. A., Chapman, V., & Barrett, D. A. (2014). Simultaneous tissue profiling of eicosanoid and endocannabinoid lipid families in a rat model of osteoarthritis. Journal of Lipid Research, 55(9), 1902-1913. https://doi.org/10.1194/jlr.M048694

We describe a novel LC method for the simultaneous and quantitative profiling of 43 oxylipins including eicosanoids, endocannabinoids, and structurally related bioactive lipids with modified acyl groups. The LC-MS/MS method uses switching at a define... Read More about Simultaneous tissue profiling of eicosanoid and endocannabinoid lipid families in a rat model of osteoarthritis.

Tonic modulation of spinal hyperexcitability by the endocannabinoid receptor system in a rat model of osteoarthritis pain (2010)
Journal Article

model of osteoarthritis (OA) on spinal nociceptive
processing and the role of the inhibitory endocannabinoid
system in regulating sensory processing at the
spinal level.
Methods. Experiment... Read More about Tonic modulation of spinal hyperexcitability by the endocannabinoid receptor system in a rat model of osteoarthritis pain.

Analgesic Effects of Fatty Acid Amide Hydrolase Inhibition in a Rat Model of Neuropathic Pain (2006)
Journal Article
Jhaveri, M., Richardson, D., Kendall, D., Barrett, D., & Chapman, V. (2006). Analgesic Effects of Fatty Acid Amide Hydrolase Inhibition in a Rat Model of Neuropathic Pain

Cannabinoid-based medicines have therapeutic potential for the treatment of pain. Augmentation of levels of endocannabinoids with inhibitors of fatty acid amide hydrolase (FAAH) is analgesic in models of acute and inflammatory pain states. The aim of...
