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 awarded New Investigator Scheme grant from the Biotechnology and Biological Sciences Research Council.

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.

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

Overview
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.

Background
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 (barry.mccoll@roslin.ed.ac.uk).

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.
