Brain Center Bulletin
This first digital edition of the BCRM Bulletin gives an overview of recent developments in our center. Brain Center Rudolf Magnus represents all research and (international) educational activities of the UMC Utrecht Hersencentrum. Our mission is to perform high-level research in clinical and experimental neuroscience, whilst delivering an exceptional standard of care.
March 2018, 12th edition
Neuroscience has become a prominent theme at Utrecht Science Park, with innovative research groups at the different Faculties of Utrecht University. This includes, but is not limited to, the Faculty of Sciences, Veterinary Medicine, Social Sciences and Medicine (UMC Utrecht). Many of Utrecht’s neuroscientists participate in the UU strategic theme “Dynamics of Youth”, with some of them leading the projects that make up the research core of the hub Child Expertise Center (Kinder Kennis Centrum).
Several of these exciting projects were presented at the launch of the Child Expertise Center on Thursday February 8. For example, a project led by Sarah Durston that focuses on the labels that children with developmental disorders, such as autism or ADHD, get and on how this affects these children, or a project studying the role of social play in health and disease by Louk Vanderschuren and colleagues.
While neuroscience is embedded well in “Dynamics of Youth”, this is surprisingly less so in the case of another UU theme “Utrecht Life Sciences”. Given the quality and breadth of Utrecht Neuroscience research, it should be a future goal to also be more visible and active within Utrecht Life Sciences and in Utrecht Science Park as a whole.
A first step in this direction was the organization of the Utrecht Brain Conference on December 12, 2017. Earlier in 2017, representatives of several biotech companies with offices in Utrecht Science Park met with neuroscience researchers from different Faculties of Utrecht University (including those of BCRM). The topic of this meeting was to discuss how to stimulate collaboration between neuroscientists and biotech companies and also to increase visibility at Utrecht Science Park.
The organization of a one-day research meeting in collaboration with Utrecht Life Sciences was chosen as one means to reach these goals. Utrecht Brain Conference was opened with lectures from Crossbeta, Nutricia Research and MILabs detailing their research and product development.
“An important theme was patient-focused research”
Jeroen Pasterkamp, Scientific director BCRM
This was followed by a great keynote lecture by Michael Heneka (University of Bonn) on microglia and their interaction with amyloid-beta, and several shorter talks by Utrecht neuroscientists. In addition to talks, many junior neuroscientists presented their work during a poster session. The meeting room was packed, Utrecht Brain Conference received very positive evaluations and the meeting resulted in several novel collaborations and grant applications, underscoring the need for a campus-wide forum for neuroscientific discussion. Since Utrecht Brain Conference has fulfilled this role last year, a new meeting will be organized this year, together with other activities to increase visibility of Utrecht neuroscience.
The quality of Utrecht neuroscience research is also exemplified by the researchers who received the BCRM publication, thesis and outreach awards last year at the BCRM research day; as well as by both recipients of the Rudolf Magnus Young Talent Fellowship, Franke Meye and Jinte Middeldorp. Their research plans are described in this bulletin. Other topics include the inaugural lecture of Wiepke Cahn, who calls for a more integrative approach towards patient care; an exciting new study in collaboration with the Youth Cohort in which the brains of unborn and newborn children will be studied using MRI by Manon Benders and colleagues and a novel European project led by Leonard van den Berg on ALS. It is clear that BCRM fosters excellent research, care and education and our future goal should be to better visualize our successes and expertise, both locally as well as (inter)nationally.

Brain development around birth studied using MRI
Infants who are born prematurely suffer more often from cognitive problems later in life than children who are born around the expected due date. Preterm children often have problems with concentration, planning and social functioning. Not all premature children develop those problems and it is therefore important to closely monitor these infants. Some studies show the association between early abnormal brain maturation and the development of impaired cognitive skills in extremely premature children. However, it remains difficult to study abnormal brain development when you can’t compare these infants with the normal population. Now it is time for the next step: visualization of the brain of healthy unborn and newborn children by MRI to compare them with the brain of preterm children to get a better understanding of (ab)normal brain developmental processes.
The brain is a complex system that is largely formed during pregnancy. After a full-term pregnancy, the brain morphology at birth does not differ much from that of adults. MRI brain research shows that premature birth, especially before 28 weeks gestational age, can have a significant impact on this vulnerable process.
The brain is often smaller, the maturation of the cerebral cortex often remains behind and the white matter is less developed. Follow up of these premature born children often reveal problems with concentration, planning and social functioning in these children.
Brain development of preterm infants can be compared with that of healthy children and children who have not yet been born. A unique aspect of this research is that pregnant mothers already receive an MRI scan and that the brains of the (healthy) unborn babies are already extensively mapped out. MRI in pregnancy is completely safe. There is no question of unhealthy radiation such as x-ray.
The research is part of the Youth Cohort, a collaboration between UMC Utrecht and Utrecht University. A total of 100 healthy pregnant mothers and their children will be followed in this study. A MRI scan is planned at 30-33 weeks of pregnancy, an MRI scan within four weeks after birth and another MRI scan at 7 years of age.
“Now it is time for the next step”
The latter is also special, so far children have not been followed for more than 3 to 5 years. At the age of 7 the cognitive and social development of children is more developed than at the age of 3. The longer period of follow up is therefore of great added value and of great importance to better understand brain development and its impact on development of children.
The aim of this research is to gain more insight into brain development between the 30th and 40th week of pregnancy and its relation to socio-cognitive development. Another goal of this research is to compare healthy brain development with extra-uterine brain development and its long-term outcome. This will be the PhD project of Elise Turk, under supervision of Dr. Roel de Heus, Prof. Arie Franx, Prof. Manon Benders and Dr. Martijn van de Heuvel.
“This research is a great opportunity to compare the development of premature babies with a healthy group,” says Manon Benders, professor of neonatology, “which is a joint effort with obstetricians and other youth collaborators. It is plausible that premature birth has a major (negative) influence on brain development and thus on later cognitive and social skills. The Neonatal Intensive Care Unit environment is a big thing: ventilation, a feeding probe, operations, etc.
One of the possibilities is that the brains of premature babies develop faster because of all these stimuli they get. It is not yet known, but very interesting and important for the prediction and guidance of these patients in the first years of their lives. By identifying and improving early diagnosis and risks, we can provide earlier and better therapies for children with developmental problems.”
At the Brain Center Rudolf Magnus there is, amongst others, a focus on neuromuscular diseases. ALS is one of them and a large amount of research aims to find a cure for this disease. ALS (Amyotrophic Lateral Sclerosis) is a rare neurodegenerative disorder that affects motor neurons in the brain, brainstem and spinal cord, resulting in progressive weakening of the muscles. ALS has an estimated prevalence of 40.000 patients at European level. Treatment is modestly effective at best and the majority of patients die within 3-5 years of diagnosis, often from respiratory failure.
It is a difficult search to discover the cause of ALS. Step by step new details are discovered that may have a link with the development of ALS, but there is still a long way to go. Recently, two of our researchers received important grants to learn more about this disease.
Two million euros for research on DNA change and ALS
Prof. Jan Veldink has received an ERC consolidator grant of two million euros. With the help of this grant, in the next five years he will investigate why some changes in the DNA lead to ALS in one person and not in the other.
Veldink will investigate the interaction between different DNA variations within one person and also the interaction with environmental exposures from the past. The genetic data for this research will come from another project he coordinates, Project MinE. Veldink: “Project MinE is an international collaboration, so there will be extensive exchange of data with international research groups. This includes whole genome sequencing and blood epigenetic profile data on thousands of ALS cases and controls.”
The project will take 5 years to complete. The first phase of the project will be characterized by trying to define homogenous subgroups of ALS patients based on a multitude of data elements, most notably blood epigenetic profiles as a proxy for past environmental exposures and specific clinical data. These results will be informative for subsequent genetic testing in ALS. The last phase of the project includes translating these novel findings using human derived induced pluripotent stem cell based models. Veldink: “One important result will be to identify additional genetic and epigenetic variations that modify the toxic expression of known ALS mutations, which could explain why some people get ALS with a specific genetic mutation but others don’t.”
Veldink has two main expectations on this research. “After 5 years, we will better be able to inform patients and their family members more precisely regarding the risk of developing ALS if they carry one or more ALS risk variants. Also, new cellular models will be available that will help speed up specific drug screening programs in ALS, both by academic and industry groups.”

Horizon 2020 grant for research on safety and efficiency of TUDCA in ALS
Prof. Leonard van den Berg received an Horizon 2020 grant, in collaboration with 10 ALS centers from 7 European countries: UK, Ireland, Italy, France, Germany, Belgium and the Netherlands. This study has the ambition to develop a novel therapy in patients with ALS, based on administration of tauroursodeoxycholic acid (TUDCA) in addition to riluzole. The hope is that this can slow down the ALS process.
This research concerns a randomized control trial on safety and efficiency of TUDCA in patients with sporadic ALS. Van den Berg and his team will play an important role in writing the study protocol. Van den Berg: “The preparations for this research are ongoing. We are aiming to start this trial, which will take 18 months, later this year. The aim is to see whether TUDCA is effective in ALS. Two biomarkers will be measured: neurofilament levels in the CSF and serum and MMP-9 expression in serum. It would be very important to find better biomarkers for disease progression in ALS.”
As ALS is a rare disorder, collaboration with other centers is very important to make progress. Van den Berg: With TRICALS, the European Trials Consortium to Cure ALS, we are aiming to set up many more ALS trials in the coming years.”

Awards on the BCRM Research Day
The theme of the BCRM Research Day on October 27 2017 was ‘The patient as partner in research’. There were several lectures by researchers and patients. PhD students held a blitz presentation to make others curious about their posters and there was a keynote lecture by Annelien Bredenoord about ethics in healthcare. At the end of the day the announcement of the various prize winners took place.
Marjolijn Ketelaar won the Outreach Award 2017. The jury praised her for the fact that she gives patients a substantial role. “This is unique, very important and an inspirational example to others.” Marjolijn is the program leader of the research line for child rehabilitation at the Utrecht Center for Rehabilitation Medicine Utrecht at the UMC Utrecht Brain Center Rudolf Magnus.
She has been involving patients in her research for a long time and has been able to link her work as a researcher to the lives of the patient. She really sets the standard for all researchers in the Brain Center on how to involve patients in their research.
Wouter van Rheenen won the Research Award 2017. This was for his publication entitled: ‘Genome-wide association analyses identify new risk variants and the genetic architecture of amyotrophic lateral sclerosis’. (Nat Genet. 2016 Sep;48(9):1043-8) The jury praised his role in research and publication with a broad scientific impact. Chantal Tax won the Thesis Award 2017 for her thesis entitled ‘Less Confusion in Diffusion MRI’. “An impressive thesis with excellent quality and quantity of research and a great clinical relevance” according to the jury.
The winner of the Poster Award was Renata Baptista Vieira de Sá. She had the best poster presentation entitled: ‘Establishing a patient-derived organoid model for studying cortical thinning in ALS’.

Awards on the BCRM Research Day
About sixty percent of psychiatric patients have physical disorders and about thirty percent of patients with a physical disorder also have psychiatric problems. During the past decades medicine has become ‘superspecialized’ focusing on just one illness and/or one underlying mechanism. As a consequence, a broader understanding of illness and the development of new treatments is restricted, according to Wiepke Cahn, Professor of Physical Health in Psychiatric Disorders at the UMC Utrecht Brain Center Rudolf Magnus. During her inaugural lecture on September 12th 2017, Cahn called for health care professionals to create a more integrated approach to illness, the person in his environment. “We should not pigeon hole in medicine and doctors should view and treat patients as a whole”
Wiepke Cahn: The separation of mental health care and hospital care hinders the recovery of many patients
According to Wiepke Cahn, physical health has been neglected in psychiatry. “The life expectancy of persons with a chronic psychiatric disorder is decreased by 15-20 years. The main cause of death is cardiovascular disease, but other physical conditions such as diabetes and cancer are also more common in patients with psychiatric disorders. This reduced life expectancy can be explained by many factors including prejudice and access to hospital care.
Care in the neighborhood
Cahn sees various opportunities to achieve a longer and better life for patients with mental health problems. “Research into finding the right balance between the effects and side-effects of medication. In addition, we should help patients to improve their lifestyles. To change unhealthy behavior is not easy, especially if you are feeling unwell. To enable this change specialized support is essential.
But most importantly a different health care organization is required in the Netherlands. Health care that is organized around the patient and family, in the neighborhood, where doctors and other disciplines collaborate and hospital care is only used when the care needed supersedes (intensive) home treatment. Integrating mental health care with hospital care give patients a better chance of recovery and ultimately leading to a healthier society.”
Rudolf Magnus Young Talent Fellowships for Frank Meye and Jinte Middeldorp
In order to support gifted junior group leaders implementing their own research line, Brain Center Rudolf Magnus awards one to two Rudolf Magnus Young Talent Fellowships each year. This year the Fellowships went to Frank Meye and Jinte Middeldorp. The Fellowship provides the recipients with €150.000 to be spent on research as the recipient sees fit.
Frank Meye will use the fellowship for doing research in rodents. He intends to unravel -with much higher spatiotemporal resolution than is feasible in humans- how specific parts of the prefrontal cortex are involved in inattentive and impulsive behavior. Furthermore, he aims to determine how Transcranial Magnetic Stimulation (TMS) with distinct parameters, alters the function of separate populations of prefrontal cortex neurons and if these TMS protocols are capable of (durably) improving attention and impulse control.
Meye: “I am very happy to have been awarded this Fellowship. It creates the opportunity to apply our approaches in a new and very translational way to tackle clinically-relevant questions. I am proud to work in an institute that dares to support high-risk and potentially high-gain research.”
Jinte Middeldorp: “I am very pleased to have received this Fellowship, which will help develop my own research line. I am currently studying the effects of the aged systemic environment (blood) in mice, with a focus on the role of astrocytes in the neurovascular unit, but it is essential to study human cells and human brains as well. This fellowship will allow me to set up novel tools for studying these cell types in the human context and that of neurological disorders. I am eager to translate my findings from mice to humans with this fellowship and to get a step closer in knowing how astrocytes interact with the vasculature and respond to changes in the systemic environment in relation to aging and disease.”
The jury praises both recipients for their high quality of publications over the last years and sees a number of possibilities for implementation of their translational research in the future. Talented junior scientists are often confronted with limited funding periods and hence a relatively short period of time in which to strengthen their profile. To allow this group of gifted scientists more time to build their own research line and optimally prepare them for the next funding step, BCRM awards one to two Rudolf Magnus Young Talent Fellowships annually in competition.
