Research Expertise

Description

My research falls within the remit of Neuropsychopharmacology, a discipline that links neuroscience to the pharmacological treatment of psychiatric and neurological disorders. My work contributes to understanding the psychopharmacology of nitric oxide (NO), targeting glutamate neuronal transmission for antidepressant action, the role of stress and inflammation in the pathogenesis of brain disorders, anti-inflammatory properties of noradrenergic agents as a potential therapeutic strategy in neurodegenerative disorders and safety pharmacology of recreational drugs, reported in over 100 peer-reviewed publications in international journals. My group utilize a range of behavioural, imaging, molecular, cellular and analytical techniques including bottom up laboratory and top down clinical approaches and I have ongoing collaborations with a number of industrial partners and investigators from a variety of disciplines. Current research on neuroinflammation and glia-neuronal interactions is focused on molecular pathways including glutamate-NO, noradrenaline and tryptophan-kynurenine pathways implicated in neurodegeneration in efforts to identify pharmacological interventions of potential therapeutic benefit. Furthermore, inhibition of the glutamate NMDA receptor (NMDA-R) subtype has shown considerable promise as a drug target to produce new antidepressants that work faster, and are more effective than existing antidepressants. A working hypothesis is that targeting signalling events down-stream of NMDA-R including NO may provide a more viable approach and current research is assessing such targets for development of novel antidepressant agents. I have engaged in projects funded by the European Commission including "ReBirth", a Marie Curie funded international training network for early stage and experienced researchers; MOODINFLAME, a collaborative research project with a variety of academic and industrial partners focused on targeting the activated inflammatory response system in mood disorders; and participated in "MolCellbio", a PhD training programme funded by the Higher Education Authority. I have also received funding from Science Foundation Ireland, Health Research Board and the Irish Research Council.

Projects

  • Title
    • Targeting the noradrenergic system for anti-inflammatory and neuroprotective actions in a clinically relevant model of Parkinson's disease
  • Summary
    • Accumulation of α-synuclein (α-syn), a major constituent of pathological Lewy body inclusions in the brain associated with Parkinson's disease, leads to microglial activation. Therapeutic approaches that reduce microglial activation may halt development and progression of neurodegeneration. Noradrenaline is a neurotransmitter known to elicit anti-inflammatory actions in the brain by stimulating specific receptors expressed by microglia. We propose that increasing noradrenaline's availability or targeting its receptor will ameliorate α-syn associated microglial activation, inflammation and degeneration of neurons. This project will determine whether targeting noradrenaline to elicit anti-inflammatory effects in the brain translates into neuroprotective effects.

  • Title
    • Assessment of a neuroprotective role for noradrenaline in combating alpha-synuclein-related neuroinflammation toward a new treatment strategy for Parkinson's disease.
  • Summary
    • Accumulation of the alpha-synuclein protein in the brain is a pathogenic hallmark of Parkinson's Disease, and is understood to trigger neuroinflammation, neurodegeneration, motor deficit and cognitive decline in patients with the disease. It has been established that the neurotransmitter Noradrenaline (NA), upon interaction with its receptor (beta2-adrenoceptor), has potent anti-inflammatory properties, and is innate in maintaining an immunosuppressive environment within the brain. While compelling evidence from experimentation with inflammatory models of Parkinson's highlights robust neuroprotective effects of drugs targeting NA, the ability of such drugs to ameliorate alpha-synuclein-induced neuroinflammation, neurodegeneration, motor and cognitive deficits in clinically relevant models of Parkinson's is unknown. To address this question, this project will determine if targeting beta2-adrenoceptors alleviates alpha-synuclein-induced microglial activation and associated neurotoxicity in cultured animal and human cells. Additionally, this project will establish an experimental model which simulates the clinical and pathological features of Parkinson's, and apply the model to determine if NA, or other pharmacological interventions which directly stimulate beta2-adrenoceptors, ameliorate the pathogenic features of the disease induced by the delivery of pathogenic forms of alpha-synuclein to the brain. The results will indicate if pharmacologically targeting beta2-adrenoceptors has the propensity to regulate the neuroinflammatory phenotype in vivo, and be a neuroprotective strategy against inflammation-induced neurodegeneration. In accordance, clinical agents such as beta2-adrenoceptor agonists may prove useful as protective agents in the treatment of neurodegenerative conditions associated with brain inflammation.

    • Old drugs, new tricks. Beta2-adrenoceptor agonists for Parkinson's disease
  • Summary
    • In my laboratory we are examining the impact of alpha-synuclein on microglial cells with a particular focus on neuroinflammation. Having simulated Parkinson's in experimental models, the next step involves finding new drugs, or repurposing old ones, that can treat the disease by reducing inflammation. Over the last number of years, work in my laboratory has demonstrated beneficial effects of noradrenaline (NA) and drugs which activate the beta2-adrenoceptor in combating neuroinflammation. This project will potentially deliver a new treatment for Parkinson's by focusing on the repurposing of NA drugs to reduce inflammation and protect the brain from degeneration.

  • Title
    • Connecting Connecting Pratchett, Brain Health and Neuroscience: Advancing Our Understanding and Treatment of Alzheimer's Disease
  • Summary
    • Acclaimed comic fantasy writer, Terry Pratchett, author of the popular Discworld series of novels became one of the most vocal advocates for research into Alzheimer's Disease after being diagnosed with a form of Alzheimer's disease in 2007. Pratchett donated $1 million to the Alzheimer's Research Trust for treatment research, and documented his own experiences with the disease and related issues in several documentaries. He spoke publicly about his condition at Trinity College Dublin, when he held an adjunct professorship. Sadly, Pratchett died from Alzheimer's disease in 2015. Now, the College maintains its link with Pratchett through ground-breaking interdisciplinary research into his life and work, under the banner of "The Pratchett Project". A central aim of the Project is to carry on Pratchett's mission to advance understanding of Alzheimer's disease, a degenerative brain condition that causes a loss of memory, difficulty thinking, problems with judging space and distance, and trouble speaking and understanding language. This project will combine three of Trinity's strengths: it's thriving research culture in Neuroscience (tcd.ie/Neuroscience), it's work in brain health at the Global Brain Health Institute (gbhi.org) and it's unique Pratchett Project (facebook.com/PratchettProject). It will develop the findings made possible by Pratchett's donation, along with his spirit of advocacy and the quest for scientific discovery, in a fully interdisciplinary programme. This programme will not only advance Alzheimer's research, but will also develop new methods for translating the findings and their implications for the community. It will allow a doctoral researcher to undertake cutting-edge research on the impact of noradrenaline on brain cell loss, something that is relevant not only to neurodegenerative diseases like Alzheimer's disease, but also to brain aging. At the same time, this programme will develop new ways to share neuroscience research and its implications with the general public, advancing Alzheimer's research, advocating to destigmatise the disease, and attracting further support, all, as Pratchett said: "to get this thing out of our hair". There is a collaborative project team in place. Andrew Harkin leads a laboratory-based research group in Trinity College Institute of Neuroscience, specialising in inflammation, neuronal atrophy and brain degenerative conditions. Brian Lawlor is co-director of GBHI and has extensive clinical experience in the field of Alzheimer's research. James Hadley of the Trinity Centre for Literary and Cultural Translation leads the Pratchett Project, coordinates its various strands, and liaises with the Pratchett estate.

    • Marie Curie Initial Training Networks (ITN): FP7-PEOPLE-2012-ITN Brain Imaging Return to Health "reBIRTH" (see http://www.rbirth.eu/) The r'BIRTH consortium is a Marie Curie Initial Training Network that gathers experts on molecular mechanisms of age-associated pathologies including neurodegeneration and depression. They work together to identify stress-regulated molecules provoking neuronal atrophy and hindering neurogenesis, and monitor the consequences of these processes in human brain. At the cellular level, diminished birth of new neurons (neurogenesis) contributes to cognitive decline and increased depressive and anxiety disorders that are associated with ageing. The work is funded by the European Commission (FP7) under the sub-programme PEOPLE (Marie Curie Actions). 16 early stage researchers will be trained in the topics of the programme i.e. molecular imaging (MRI), proteomics, immunotechnology, high content screening, molecular neuroscience, neuropharmacology and patient studies. The training is provided by seven universities, two private companies and one non-profit research organisation from 7 European countries.

  • Title
    • Early diagnosis, treatment and prevention of mood disorders targeting the activated inflammatory response system.
  • Summary
    • [Acronym: MOODINFLAME] 2008-2013. A collaborative, large-scale focused research project entitled "Early diagnosis, treatment and prevention of mood disorders targeting the activated inflammatory response system. [Acronym: MOODINFLAME]. A consortium of 14 European Universities/Research Institutes and 4 SMEs have come together for this project with the overall objective of developing biomarker tests for mood disorder patients based on an activated inflammatory response system (IRS) and inflammation-mediated disturbances in tryptophan metabolism. As part of this programme patients are treated with drugs to counteract the consequences of an activated IRS/disturbed metabolism of tryptophan. The project leads to an enhanced understanding of the pathogenesis of inflammation-related mood disorders, and of the mechanism of anti-inflammatory drugs and drugs targeting tryptophan metabolism in treating depressive behaviour.

    • Neuronal nitric oxide synthase: A novel target for antidepressant activity
  • Summary
    • Inhibition of N-methyl-D-aspartic acid receptors (NMDA-R) has shown considerable promise as a drug target to produce new antidepressants that work faster, and are more effective than existing antidepressants. However, targeting NMDA-R directly is problematic due to adverse effects. We hypothesise that targeting signalling events down-stream of NMDA-R may provide a more viable approach. nNOS is a down stream target of NMDA-R. We have published a number of original papers demonstrating that 1) NOS inhibitors have antidepressant properties 2) such properties are dependent on endogenous serotonin and 3) NOS inhibitors can augment the effects of conventional antidepressants in preclinical models. Currently our research is assessing the efficacy of nNOS inhibitors as novel antidepressant agents. A future aim is to determine if uncoupling the NMDA-R from nNOS can elicit antidepressant actions.

    • Caffeine exacerbates the acute toxicity of 3,4 methylenedioxymethamphetamine (MDMA; "Ecstasy"): A role for dopamine ?
  • Summary
    • Co-administration of caffeine profoundly enhances the acute toxicity of MDMA. This project will elucidate the mechanism underlying a potentially serious drug interaction between caffeine and MDMA and clarify risks associated with the concurrent consumption of caffeine with other drugs which increase dopaminergic transmission.

  • Title
    • Caffeine promotes hyperthermia and serotonergic loss following co-administration of the substituted amphetamines, MDMA
  • Summary
    • The project determined the effect of caffeine co-administration on the core body temperature response and long-term serotonin (5-HT) loss induced by methylenedioxymethamphetamine (MDMA; "Ecstasy") and its metabolite methylenedioxyamphetamine (MDA; "Love"). Caffeine promotes hyperthermia, tachycardia and long-term central serotonin loss associated with MDMA and MDA. This is a serious drug interaction, which could have important acute and long-term health consequences for recreational drug users.
