Systemic Analysis of Successful Spinal Cord Regeneration in Larval Zebrafish
The Centre for Neuroregeneration is pleased to announce its involvement in a new PhD project to better understand how the zebrafish central nervous system (CNS) can regenerate. The successful applicant will help to identify how different cells and cell types of the injured spinal cord interact to lead to functional recovery (swimming capability) in the zebrafish CNS. The project aims to clarify the molecular signals controlling successful neuronal and axonal regeneration, as well as their subsequent re-myelination. The student will screen chemical compound libraries in an unbiased approach to identify pathways controlling these processes.
This project uniquely draws together the expertise present in three groups. The student will work with the Centre’s Prof Catherina Becker (an expert in spinal cord regeneration) and Dr David Lyons (an expert in myelination and remyelination in zebrafish), as well as Prof Keith Sillar from St. Andrews University provides detailed knowledge about the spinal locomotor network and electrophysiolog.
Further details of teh PhD and how to apply are on the EASTBIO Doctoral Training Partnership website.
Zebrafish Shed Light on Nerve Cell Repair
Tropical fish may hold clues that could aid research into motor neurone disease and paralysis caused by spinal cord injury. Scientists have discovered that a hormone called serotonin – better known for its role as a mood booster – can help zebrafish to recover from a spinal cord injury.
The Centre for Neuroregeneration's Dr Thomas Becker said, "Understanding how zebrafish are able to repair damaged nerves could one day help us to trigger similar mechanisms in human stem cells. Our hope is that this may eventually lead to new treatments for conditions such as motor neuron disease, for which there is no cure."
Edinburgh Researchers Part of New £1.3m UK SMA Research Consortium
Professor Tom Gillingwater (CIP) and Professor Catherina Becker (CNR) are to be part of a new collaborative initiative for Spinal Muscular Atrophy research in the UK over the next 3 years. The consortium will consist of world-class research/clinical experts based in Oxford, Edinburgh, London and Sheffield Universities. It will be led jointly by Professor Kevin Talbot (University of Oxford) and Professor Tom Gillingwater (University of Edinburgh). The intention is to form an initial nucleus that will, in time, draw together other leading UK scientists.
The new UK Research consortium is the first of its kind for SMA and is being announced on 29th September 2015 as part of the first ever UK SMA Awareness Week. It has come about because of impressive recent progress, leading to an ever-increasing need for research collaboration, not just within the SMA field, but in the overlap areas with other neuromuscular conditions like Muscular Dystrophy and Motor Neurone Disease. The main aims are to: i) further develop existing drug targets and identify new neuroprotective therapies to maintain function throughout the lives of people living with SMA, and; ii) identify improved ways of delivering treatments in order to maximise benefit throughout the body.
Joanna Mitchell, CEO of The SMA Trust comments: “These are exciting times in SMA research and for the new UK research consortium. Recent years have seen rapid advances, with several companies now actively pursuing clinical trials for potential treatments. Whilst a cure for SMA remains the ultimate goal, we also recognise that, for the time being, ‘success’ is equally likely to come in the form of combinations of treatments that improve the quality of life of people living with SMA.”
Edinburgh has been awarded funding by the Wellcome Trust for three new PhD programmes that address global health challenges.
The prestigious courses will provide students with cutting-edge training in the fields of infectious disease, translational neuroscience and tissue repair.
The 4-year programmes will begin in September 2016. The closing date for applications will be in December 2015.
The tissue repair course will train the next generation of scientists in the biology of regeneration, inflammation and fibrosis to develop future tissue repair treatments.
It will be led by Professor Stuart Forbes, of the University’s MRC Centre for Regenerative Medicine, and Professor Catherina Becker, of the Centre for Neuroregeneration.

PhD Opportunity with Dr Jill Fowler
Title: Therapeutic potential of boosting a novel anti-oxidant signalling pathway (nrf2) in mouse models of stroke and Alzheimer’s Disease
Supervisor: Dr Jill Fowler
Stroke is a major risk factor for development of Alzheimer’s Disease (AD), however the pathological mechanisms by which stroke can lead to cognitive decline are unclear. Neurons use oxygen to produce energy, and a by-product of this process is the formation of reactive oxygen species known as free radicals. Stroke can lead to over-production of free radicals, causing cell damage through oxidative stress. In the normal healthy brain, there are defence mechanisms (anti-oxidant) to prevent damage to brain cells. In particular a new signalling molecule has been discovered called Nrf2, which can switch on several antioxidant molecules and exert protection. This project will test the hypothesis that stroke leads to increased oxidative stress and cellular damage which can be ameliorated by boosting the anti-oxidant capacity of the brain through targeting Nrf2. Using a mouse model of stroke, the effects of stroke will be studied on Nrf2 related signalling pathways and Alzheimer’s Disease pathology. Secondly, it will be determined whether boosting anti-oxidant mechanisms either by drugs, or by using specialised genetically modified mice in which anti-oxidant capacity is enhanced, can protect against the effects of stroke. Techniques that will be used in this project include assessment of pathology in mouse brain sections using light and confocal microscope and biochemical techniques to measure proteins which contribute to neuropathology.
This a three year PhD studentship funded by Alzheimer’s Research UK, based at the Centre for Neuroregeneration. Funding will commence in September or October 2015. This is only availabel to EU Students.
Dr HongYan Zhang has been awarded a £400K New Investigator Scheme grant from the Biotechnology and Biological Sciences Research Council to study how spinal neural circuits generate flexible motor output.
Animals can perform various rhythmic movements, like walking, running and swimming, and they are able to precisely control the speed of these movements by flexibly adjusting muscle contractions. Such ability is achieved by coordinated activities of nerve cells in the spinal cord. Using Xenopus embryos and larvae, Dr Zhang and her team will record individual spinal nerve cell and motor nerve activities simultaneously. They will test how spinal nerve cell properties develop, how their interactions change, and how variable swimming speed can be generated. Understanding how spinal nerve cells control movement in simple animals, like Xenopus tadpole, will help us to understand more complex systems, such as movement control in humans.
Dr Leah Herrgen has received a Wellcome Trust-University of Edinburgh Institutional Strategic Support Fund award. She will use her award to hire a research assistant, who will help her to establish an imaging setup to investigate how zebrafish recover from traumatic brain injury.

MS Society £2 million Funding
The MS Society today announced it is investing a further £2 million into a world-class MS research hub known as the Edinburgh Centre for MS Research.
The funding will support a team of approximately 15 world-leading researchers at the University of Edinburgh, co-directed by Professors Charles ffrench-Constant and Siddharthan Chandran, to continue their ground-breaking work into understanding the causes and mechanisms behind MS and finding ways to slow or stop disease progression.
The multi-disciplinary team is made up of investigators from across the University, primarily in the Centre for Clinical Brain Sciences, MRC Centre for Regenerative Medicine and Centre for Neuroregeneration. In addition, the Anne Rowling Clinic will provide an interface between the laboratory-based basic science and clinical research.
Partnerships with the Cambridge Centre for Myelin Repair, the MS Society Tissue Bank (Imperial College London) and the UK MS Register (Swansea University) are integral and vital to the success of the venture.
Over the next 5 years, the Edinburgh Centre will focus their research on stem cells, in the hope of building a clearer picture of how MS develops and a better method for modelling the condition and finding effective treatments. Their crucial insights into the underlying biology of MS will inform treatment development and pave the way for innovative new therapies to repair the damage that occurs in MS.
Professor Siddharthan Chandran, Co-Director of the Edinburgh Centre for MS Research, said: “In Scotland we are uniquely placed to conduct this world-class research, and as the country with one of the greatest burdens of this condition it is increasingly important that we should take a lead in tackling it. We are very fortunate to have a wealth of expertise in regenerative medicine, an NHS that is hardwired to support the best clinical research, and a wonderful community of patients and supporters. With their help, we hope to change the experience of MS for people around the world.”
The Centre has already made many significant breakthroughs. In collaboration with the MS Society-funded Cambridge Centre for Myelin Repair, they have found several key molecules that could play important roles in helping to regenerate and repair myelin , one of which is known as RXR-gamma. Researchers are now preparing a small clinical trial to test the safety and effectiveness of a drug that can target RXR-gamma and could potentially repair myelin in people with MS.
Professor Charles ffrench-Constant, Co-Director of the Edinburgh Centre for MS Research, said: “The value of this funding cannot be underestimated at a time when we have real grounds for optimism in MS research. Stem cells provide genuine hope as a vital tool for drug development. We are confident that they could soon help us answer the unmet need for treatments to stop, slow or reverse the symptoms of this condition.”
The MS Society is a global leader of MS research and is the leading UK charity for people with MS. Michelle Mitchell, Chief Executive of the MS Society in the UK, said: “We know that people with MS desperately want treatments that can slow, stop or reverse the effects of MS progression – and the world-class researchers at the Edinburgh Centre could be pivotal in paving the way for how the condition is treated in the future. Aside from the cutting-edge research being carried out there, it’s also a place where highly promising young scientists are being supported to embark on a career in the field of MS, ensuring that the best scientific minds are focussed on finding answers for people with the condition for years to come.”

Lyons Lab: Brain Activity Regulates Myelination
In a manuscript published in Nature Neuroscience (http://www.ncbi.nlm.nih.gov/pubmed/25849985) the Lyons group have shown that neuronal activity regulates myelin sheath production in the central nervous system (CNS). Using zebrafish as a model organism to visualise and manipulate myelination in vivo, the group have shown that disruption to synaptic vesicle release causes oligodendrocytes (the myelin producing glia of the CNS) to generate about 40% fewer myelin sheaths than normal. Intriguingly and encouragingly increasing neuronal activity promotes oligodendrocytes to generate about 40% more sheaths than normal. Future studies will reveal the underlying mechanisms and determine whether neuronal activity could be regulated for the promotion of myelin repair and treatment of diseases such as multiple sclerosis.

Roslin: Three Year Studentship funded by Alzheimer's Research UK
Neuroinflammation accompanies the progression of neurodegeneration and cognitive impairments in dementia and recent genetics studies have uncovered variants in neuroimmune genes, including loss-of-function TREM2 mutations, that increase risk of dementia. The mechanisms underlying these genetic associations and a potential causative role for TREM2-regulated processes and more broadly neuroinflammation remain to be established. This project will determine the impact of TREM2 deficiency on neuroimmune regulation, cognitive function and key pathological features of dementia in a mouse model of vascular cognitive impairment induced by chronic cerebral hypoperfusion.
Microglia are the key immune sentinels and effectors in the central nervous system and therefore exert a major influence on the neuroinflammatory environment. Numerous regulatory mechanisms prevent inappropriate or excessive microglial and neuroinflammatory activity but if disrupted this may increase the risk of neurodegeneration. TREM2 is a member of the triggering receptor expressed on myeloid cells (TREM) family of cell surface proteins and highly expressed on microglia. Recent evidence suggests TREM2 is an important regulator of microglial activity and the neuroinflammatory environment. The importance of TREM2 to dementia and neurodegeneration is highlighted by recent discoveries of TREM2 mutations that cause or increase risk of several neurodegenerative disease including dementia.
Increasing evidence supports the involvement of vascular mechanisms to dementia and age-related cognitive decline. Cerebrovascular dysfunction is a feature of Alzheimer’s disease and cerebral hypoperfusion is now recognised as an important contributor to cognitive decline and is associated with microvascular damage in the brain. The mechanisms connecting hypoperfusion, cerebrovascular dysfunction and cognitive decline/dementia are not well understood. Given that hypoperfusion and associated hypoxia, microvascular damage and endothelial dysfunction are all important inflammatory triggers, inflammation is a plausible candidate. Our recent work has shown that chronic cerebral hypoperfusion casues marked alterations in microglia associated with white matter pathology and cognitive impairments.
Aims and plans
The overriding aims of the project are to:
1. Define the temporal cellular and molecular neuroinflammatory profile, with a focus on TREM expression, in response to chronic cerebral hypoperfusion
2. Determine the impact of TREM2 deficiency on neuroinflammatory profile, key markers of white matter, neuronal and synaptic pathology and cognitive performance in response to chronic cerebral hypoperfusion
The project will involve a range of techniques including an in vivo model of chronic cerebral hypoperfusion, behavioural assessment of cognitive function, flow cytometric immunophenotyping, histology and biochemical analyses. The student will receive training in these project-specific techniques as well as high resolution microscopy, image analysis and general laboratory, analytical and presentation skills. The student will be encouraged to attend scientific meetings during the project.
Funding, environment and eligibility
The studentship is fully funded for 3y by Alzheimer’s Research UK.
The project will be supervised by Dr Barry McColl (The Roslin Institute) and Prof Karen Horsburgh (Centre for Neuroregeneration) within the College of Medicine and Veterinary Medicine.
Candidates will have a 1st class or 2:1 degree in a relevant biomedical science.
Closing date for applications is 20th March 2015. Informal enquiries to Dr Barry McColl are welcomed (email@example.com).

Becker Group awarded BBSRC Grant
The Becker group have been awarded a £480k grant from the Biotechnology and Biological Sciences Research Council to investigate the regeneration of dopaminergic cells in the zebrafish brain. Adult zebrafish have an amazing capacity to repair injuries to their brain and spinal cord. In particular, there are so-called progenitor cells in the brain that can divide and thus generate new nerve cells. In mammals, including humans, such regeneration usually fails. Nerve cells that produce the chemical dopamine, an important modulator of brain activity, are particularly vulnerable to influences of toxins, aging and disease, such as Parkinson's disease which leads to life-long disability. The Becker group will determine whether dopamine producing nerve cells are regenerated in the adult zebrafish and whether this repairs leads to recovery of lost functions. This will help them determine at a fundamental level how it is possible to replace lost nerve cells in the adult and fully wired nervous system.

Muscular Dystrophy Campaign grant success
Congratulations to Prof. Tom Gillingwater from the CIP and Prof. Catherina Becker from the CNR who have been awarded a 2 year project grant from the Muscular Dystrophy Campaign.
Working with mouse and zebrafish models of spinal muscular atrophy (SMA) will allow to understand the molecular basis of why some motor neurons are particularly vulnerable in the disease, whereas others are resistant to the disease.
This will hopefully lead to the identification of pathways that can act as novel therapeutic targets for the treatment of SMA and related neurodegenerative conditions.
The Muscular Dystrophy Campaign supports excellent research projects, aiming to find treatments and cures for muscular dystrophy and related neuromuscular conditions.
