Brain Matters 2016 The newsletter from Queen Square Brain Bank for Neurological Disorders Welcome Professor Tom Warner, Clinical Director of Queen Square Brain Bank welcomes you to the eleventh edition of Brain Matters. “As the Queen Square Brain Bank (QSBB) entered its fourth decade we said goodbye to one of its most loyal staff. Susan Stoneham, featured in Brain Matters 2015, retired in January after twenty five years working as administrator to QSBB and The Sara Koe PSP Research Centre. Over the years, many donors, their relatives and friends will have spoken to or even met Susan. Always calm, courteous and charming, she worked tirelessly to orchestrate the “front of house” of QSBB ensuring its smooth running and acting as its public face. She had unique skills and her empathetic manner and organisation will be greatly missed by her friends, colleagues and, most importantly, those on the brain donor scheme and their families. Finding a successor to Susan was going to be a difficult task and I am pleased to introduce Lynn Haddon who was appointed from a very competitive field of candidates. Lynn brings many qualities and skills from previous experience as administrator to a large academic department at Queen Mary University of London and from her work with patients and their relatives at The Barts Cancer Institute. She also has in depth IT experience which will be invaluable as we update our computer systems and database. Over the last year there has been increasing political and media coverage of dementia and its effect on the ageing population. As with other neurodegenerative disorders such as progressive supranuclear palsy and multiple system atrophy, the study of brain tissue plays a critical role in understanding how the brain cells involved die, and in identifying potential ways this can be treated. At QSBB we continue to work closely with the Dementia Research Centre at the National Hospital for Neurology and Neurosurgery, led by Professor Nick Fox, to encourage donation from well-studied patients with the commonest forms of dementia, familial Alzheimer’s disease and frontotemporal dementia. This productive collaboration complements our ongoing research programme investigating the causes of Parkinson’s disease and atypical parkinsonism as the most prevalent forms of neurodegeneration. Finally, I would like to emphasise that the world class reputation of QSBB is entirely based on the selfless generosity of brain donors and their families, to whom we are very grateful.” Lynn Haddon – photo courtesy of PSPA Research Updates This new information could be key to developing a strategy to alter the course of progression and ultimately to stop the disease in its tracks.” Image (left) shows Christina collecting samples of tissue to be analysed Professor Janice Holton, Neuropathology Director and Dr Aoife Kiely, Research Fellow continue their studies in multiple system atrophy, funded by the Multiple System Atrophy Trust and MSA Coalition: Ms Christina Murray, PhD student, and Dr Sonia Gandhi, Wellcome Trust Fellow and Consultant Neurologist give an update on their study, funded by Parkinson’s UK: “The aim of our project is to investigate the way in which Parkinson’s disease (PD) begins and progresses in the brain. As the disease advances, the brain pathology increases in severity and spreads to affect many areas. We wanted to explore the earliest pathological changes that occur using a technique called proteomics, which is the investigation of all the proteins present in a cell or brain tissue at any one time. Proteins are the basic building blocks of all cells and if defective can disturb normal functioning. The brain, a complex organ contains thousands of different proteins and our proteomics technique provides a snapshot of several of these, including defective ones. We analysed brain samples donated from individuals who had early signs of PD during life. At this stage only certain brain areas are affected with Lewy bodies, the pathological hallmark of PD, made up of a protein called alpha-synuclein. Other regions are spared until later in the disease development. Previous studies show that mitochondria, which produce energy for the cell and are crucial for cell function, become dysfunctional in Parkinson’s disease. However, it is not known whether abnormal mitochondria function precedes the pathology. Our findings imply that this could in fact be the case. Mitochondrial proteins are changing in brain areas in PD that do not yet have pathology but would at a later stage, suggesting that mitochondrial dysfunction appears to be one of the first processes to be affected. “The multiple system atrophy (MSA) research group at QSBB is utilising diverse methods to understand the cause of MSA. So far our work has shown that the immune system of the brain may not be functioning properly in this disease resulting in over activity known as neuroinflammation. We used state of the art technology to look closely at a large number of indicators of inflammation in brain regions typically affected. This has given us a unique opportunity to find several new targets for future studies that may be valuable in developing treatments for the disease. We have begun experiments, in collaboration with Professor Seth Love’s group in Bristol, examining the protein alphasynuclein which builds up in brain cells in MSA. In a healthy brain specialised enzymes would usually breakdown and clean out any alpha-synuclein that has accumulated. However, we believe that these enzymes are probably not working effectively in MSA, causing build-up of this sticky protein and we are keen to find reasons for this. By examining the levels and activity of enzymes in a large number of MSA brains, comparing them to normal ‘control’ brains, we aim to confirm our hypothesis. We can grow cells in a dish in the laboratory (called ‘in vitro’) and treat them with a virus which carries DNA to code for alpha-synuclein so that this protein can be produced. By adding different combinations and concentrations of enyzmes we hope to determine if we can improve the breakdown of alphasynuclein. We are excited to find out the results of these experiments as ultimately they could provide new ways to consider treating MSA.” Research Updates Dr Helen Ling, Research Associate and Emeritus Professor, Tamas Revesz are investigating a topical subject, chronic traumatic encephalopathy: “Repetitive head injury can cause long term irreversible damage to the brain years after exposure to the injury. The condition ‘chronic traumatic encephalopathy’ (CTE), previously known as dementia pugilistica, was initially recognised in retired boxers. We now know it can occur in individuals pursuing other sports and activities which may result in repetitive head trauma. The clinical symptoms include progressive dementia, changes in personality and speech, and balance and movement abnormalities. The pathology is characterised by the accumulation of abnormal tau protein. We all have tau protein in our brain but when it clumps together, the protein no longer functions normally and can lead to brain cell death. We studied the brain tissue and clinical records of 268 donors with different pathological diagnoses including progressive supranuclear palsy (PSP), Alzheimer’s disease, corticobasal syndrome, frontotemporal lobar degeneration, multiple system atrophy and healthy elderly individuals. Our findings confirm that individuals with a history of traumatic brain injury during life are more susceptible to developing CTE pathology. Many had suffered concussion, some had participated in sports prone to head injury such as rugby, and some were military veterans. We also found CTE pathology more commonly in PSP, with around a quarter of the cases affected. This higher incidence could be the consequence of these patients experiencing sustained multiple falls, which are more prevalent in this disease than in others. However, in our cases the CTE changes were mild and they may not have contributed to the clinical symptoms. Dillwyn Smith, Artist in Residence at Queen Square Brain Bank since 2013 is creating artwork which offers a unique opportunity to engage the public with brain donation and the techniques used in post mortem diagnostics and research. The project is sponsored by The Virginia Keiley Benefaction, and Francis and Renee Hock Foundation: Through observational drawing at QSBB and from memory in his studio, Dillwyn is producing a body of work entitled ‘Silvering the Cerebrum’. ‘Silvering’ refers to a particular staining technique synonymous with neuropathology and used when identifying various cells under a microscope. The discovery of stains (also called aniline dyes) and their application within the scientific and artistic worlds over a hundred years ago led to the development of methods which continue to be used in everyday pathological practice. The interrelationship of science and art is not a new one. Dillwyn is influenced by the artist William Morris who experimented with aniline dyes when making his work and whose workshop and home was 26 Queen Square, London between 1865 and 1881 (now the site of The National Hospital for Neurology and Neurosurgery). Further research is needed in the near future to unravel the mechanisms of CTE pathology as there are many unanswered questions.” Dillwyn’s aesthetic studies of neuropathology practice provide alternative insights into the brain, and highlight the important work and continued need for brain banks. Image (top right) shows a microscopic view of abnormal accumulation of tau protein (in brown) surrounding a blood vessel in brain tissue affected by CTE Following a successful exhibition in 2015, a symposium is planned for April 2016 at the National Hospital for Neurology where artists, scientists and members of the public will be invited to attend, view the artwork and participate in a discussion of the relationship between art and medical science. Some of the artworks are for sale with a proportion of all sales going to Queen Square Brain Bank.

I took an opportunity during my degree to work at Novartis Pharmaceuticals in Basel, Switzerland where I used human muscle cells as part of my project. This sparked my passion for scientific research and I went on to do a PhD in Learning and Memory. I knew my ultimate goal was to study the mechanisms involved in neurodegenerative diseases and in September 2014 I began working at QSBB as a senior research technician. I feel privileged to have this unique position where I can contribute to research as well as to the day to day running of the brain bank. Last year we had a Human Tissue Authority (HTA) inspection lasting two days (brain banks are required by law to be licensed with the HTA) and I helped to log all frozen tissue from over two thousand brains which are stored here in freezer rooms. I also recently trained as a medical photographer and during the weekly brain dissection I can now take high quality images which are often used in medical education and displayed at scientific meetings worldwide. My own experiments involve utilising brain tissue from donors who had multiple system atrophy (MSA) in life, as part of a project funded by the Multiple System Atrophy Trust. The brain bank provides a valuable resource of tissue matched with donors’ medical records. One of my first tasks was to create a database detailing all 232 MSA cases, the largest collection in the UK, with the pathological and clinical information. This now serves as a resource for researchers studying this poorly understood degenerative condition. It is a real pleasure and honour to work at QSBB, every day is interesting, and I hope to continue to participate in new projects for the foreseeable future.” Donations The importance of controls We would like to encourage people without a neurological condition, ‘controls’ to register with our donor scheme. Controls are vital in providing researchers with an understanding of the normal appearance and function of the brain, and for comparison with the diseased brain. Brain donation coordinators Lynn Haddon, who recently joined QSBB as administrator, is the first point of contact for potential donors. She is responsible for coordinating the brain donor scheme and along with Linda Parsons, laboratory manager and Robert Courtney, senior technician, organise the safe receipt of donated brains. Lynn, Robert and Linda provide an on-call service during evenings and weekends, and liaise with relatives, hospital staff, funeral directors and couriers, to ensure the careful donation of the brain with the minimum of distress to the relatives of the deceased.
