Analysis of reactive astrocytes and NG2 proteoglycan in ex vivo rat models of spinal cord injury
Patar, Azim; Dockery, Peter; Howard, Linda; McMahon, Siobhan (Elsevier, 2018-09-26)Background: The use of animals to model spinal cord injury (SCI) requires extensive post-operative care and can be expensive, which makes an altemative model extremely attractive. The use ofex vivo slice cultures is an ... -
Cell viability in three ex vivo rat models of spinal cord injury
Patar, Azim; Dockery, Peter; Howard, Linda; McMahon, Siobhan S. (Wiley, 2018-11-11)Spinal cord injury (SCI) is a devastating disorder that has a poor prognosis of recovery. Animal models of SCI are useful to understand the pathophysiology of SCI and the potential use of therapeutic strategies for human ... -
Chondrocytes derived from mesenchymal stromal cells and induced pluripotent cells of patients with familial osteochondritis dissecans exhibit an endoplasmic reticulum stress response and defective matrix assembly
Xu, Maojia; Stattin, Eva-Lena; Shaw, Georgina; Heinegård, Dick; Sullivan, Gareth; Wilmut, Ian; Colman, Alan; Önnerfjord, Patrik; Khabut, Areej; Aspberg, Anders; Dockery, Peter; Hardingham, Timothy; Murphy, Mary; Barry, Frank (Wiley, 2016-07-07)Familial osteochondritis dissecans (FOCD) is an inherited skeletal defect characterized by the development of large cartilage lesions in multiple joints, short stature, and early onset of severe osteoarthritis. It is ... -
Comparison of cellular architecture, axonal growth, and blood vessel formation through cell-loaded polymer scaffolds in the transected rat spinal cord
Madigan, Nicolas N.; Chen, Bingkun K.; Knight, Andrew M.; Rooney, Gemma E.; Sweeney, Eva; Kinnavane, Lisa; Yaszemski, Michael J.; Dockery, Peter; O'Brien, Timothy; McMahon, Siobhan S.; Windebank, Anthony J. (Mary Ann Liebert, 2014-08-08)The use of multichannel polymer scaffolds in a complete spinal cord transection injury serves as a deconstructed model that allows for control of individual variables and direct observation of their effects on regeneration. ... -
Effect of a binge-like dosing regimen of methamphetamine on dopamine levels and tyrosine hydroxylase expressing neurons in the rat brain
Moreira da Silva Santos, Andreia; Kelly, John P.; Dockery, Peter; Doyle, Karen M. (Elsevier, 2018-10-05)Methamphetamine, an amphetamine derivative, is a powerful psychomotor stimulant and commonly used drug of abuse. This study examined the effect of binge-like methamphetamine (MA) dosing (4 x 4 mg/kg, s.c., 2 h apart) on ... -
Effect of cyclosporin A on functional recovery in the spinal cord following contusion injury
McMahon, Siobhan S.; Albermann, Silke; Rooney, Gemma E.; Moran, Cathal; Hynes, Jacqueline; Garcia, Yolanda; Dockery, Peter; O’Brien, Timothy; Windebank, Anthony J.; Barry, Frank P. (Wiley, 2009-08-20)Considerable evidence has shown that the immunosuppressant drug cyclosporin A (CsA) may have neuroprotective properties which can be exploited in the treatment of spinal cord injury. The aim of this study was to investigate ... -
Engraftment, migration and differentiation of neural stem cells in the rat spinal cord following contusion injury
McMahon, Siobhan S.; Albermann, Silke; Rooney, Gemma E.; Shaw, Georgina; Garcia, Yolanda; Sweeney, Eva; Hynes, Jacqueline; Dockery, Peter; O'Brien, Timothy; Windebank, Anthony J.; Allsopp, Timothy E.; Barry, Frank P. (Elsevier, 2012-12-20)Background aims. Spinal cord injury is a devastating injury that impacts drastically on the victim's quality of life. Stem cells have been proposed as a therapeutic strategy. Neural stem (NS) cells have been harvested from ... -
Impaired recognition memory and cognitive flexibility in the rat L5-L6 spinal nerve ligation model of neuropathic pain
Moriarty, Orla; Gorman, Claire L.; McGowan, Fiona; Ford, Gemma K.; Roche, Michelle; Thompson, Kerry; Dockery, Peter; McGuire, Brian E.; Finn, David P. (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 ... -
Lentiviral vector delivery of short hairpin RNA to NG2 and neurotrophin-3 promotes locomotor recovery in injured rat spinal cord
Donnelly, Eleanor M.; Madigan, Nicolas N.; Rooney, Gemma E.; Knight, Andrew; Chen, Bingkun; Ball, Bret; Kinnavane, Lisa; Garcia, Yolanda; Dockery, Peter; Fraher, John; Strappe, Padraig M.; Windebank, Anthony J.; O'Brien, Timothy; McMahon, Siobhan S. (Elsevier, 2012-01-08)Background aims. In this study we investigated the effect of neurotrophin-3 (NT-3) and knockdown of NG2, one of the main inhibitory chondroitin sulfate proteoglycans (CSPG), in the glial scar following spinal cord injury ... -
Lentiviral vector‐mediated knockdown of the neuroglycan 2 proteoglycan or expression of neurotrophin‐3 promotes neurite outgrowth in a cell culture model of the glial scar
Donnelly, Eleanor M.; Strappe, Padraig M.; McGinley, Lisa M.; Madigan, Nicolas N.; Geurts, Elizabeth; Rooney, Gemma E.; Windebank, Anthony J.; Fraher, John; Dockery, Peter; O'Brien, Timothy; McMahon, Siobhan S. (Wiley, 2010)Background Following spinal cord injury, a highly inhibitory environment for axonal regeneration develops. One of the main sources of this inhibition is the glial scar that is formed after injury by reactive astrocytes. ... -

Clancy, Cillian; Khan, Sonja; Glynn, Claire L.; Holian, Emma; Dockery, Peter; Lalor, Pierce; Brown, James A.L.; Joyce, Myles R.; Kerin, Michael J.; Dwyer, Róisín M. (IOS Press, 2017-01-03)BACKGROUND: Cells release extracellular membrane vesicles including microvesicles known as exosomes. Exosomes contain microRNAs (miRNAs) however the full range within colorectal cancer cell secreted exosomes is unknown.OBJECTIVE: ...
