Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is characterized by profound and/or pathological fatigue and malaise. It can be aggravated by physical or cognitive efforts at intensities previously well tolerated by the individual. The symptoms are persistent or recurrent over long periods of time and lead to a significant reduction in functioning and cannot (yet) be explained by a somatic cause. Also the molecular and cellular mechanisms in the brain that underlie ME/CFS are currently not known.
We are looking for an ambitious and enthusiastic PhD candidate to help us unravel this largely unexplored, burdensome and complex disorder. The position is supported by a recently awarded ZonMw grant, and is part of a larger Dutch consortium on ME/CFS. This project concerns a collaboration between the University of Amsterdam (
Brain Plasticity group, Swammerdam Institute for Life Sciences (SILS) in the Faculty of Science), the Amsterdam UMC and the
Neuroimmunology group of the Netherlands Institute for Neuroscience (NIN). You will be working both at the SILS and at the NIN.
Research in our consortium aims at advancing fundamental knowledge of the neurobiology of ME/CFS, using state-of-the-art molecular methods in neuroscience. Together with societal partners, we aim to translate fundamental knowledge and novel insights into solutions for societal problems.
The aim of this project is to make first steps into improving our understanding the molecular and cellular alterations in the brain in relation to fatigue, such as they occur in ME/CFS and in Long Covid, for which we will use human post-mortem brain tissue and study related pre-clinical fatigue model systems (mice and/or primates).
Together with ME/CFS patient associations and the Netherlands Brain Bank, a brain donor program is initiated to make brain tissue of ME/CFS patients available for scientific research. Using the collected human brain tissue, you will characterize proxies for the stress response, microglia-neuron interactions, and energy/mitochondrial metabolism, all of which have been implicated in brain functioning and have been proposed to contribute to ME/CFS. The methods to be used are quantitative immunohistochemistry, STED microscopy, mitochondrial metabolic measures and (bulk, single cell and/or spatial) transcriptomics.
Are you fascinated by the human brain and the neurobiology of disease, and do you want to contribute to elucidating the brain mechanisms behind this debilitating disorder? Then this is the job for you!
What are you going to do? You will help set up the donor program and assist in building the human ME/CVS brain cohort. You will perform a first, in-depth characterization of the brains of ME/CFS patients and their controls. You will study changes in (1) their HPA stress axis, (2) their resident immune cells, and (3) their mitochondrial energy metabolism, focusing on various brain regions; the hypothalamus, hippocampus, cortical grey matter and subcortical white matter of diagnosed ME/CFS, long-COVID and control brains using immunohistochemistry, flow cytometry, qPCR analysis and (single cell) RNA sequencing. A related project with TNO Rijswijk on fatigue after COVID involves the study of similar changes in relation to COVID infection in post-mortem primate brains.
Tasks and responsibilities: - complete a PhD thesis within the official appointment duration of four years;
- work with pre-clinical disease models, such as mice and primates, as well as post mortem human tissue;
- use (single cell) RNA sequencing of post-mortem brain tissue to explore the changes in gene expression;
- use quantitative immunohistochemistry of corticotropin-releasing hormone (CRH) and
CRH/arginine vasopressin (AVP)-co-expression and glucocorticoid-receptor expression in hypothalamic
and hippocampal neurons to analyze HPA-axis activity;
- quantify and determine the phenotype(s) of microglia and T cells in cortical regions using quantitative
immunohistochemistry;
- explore mitochondria function and structure using qPCR and immunohistochemistry;
- perform experiments in a systematic and well-controlled manner and keep accurate records by properly
documenting and organizing your work;
- be an active member of the research groups and take responsibility for shared tasks. Discuss your work
with the group leaders, colleagues at all three institutes and during national consortium meetings.
Incorporate feedback and give input to others;
- take a leading role in writing manuscripts and incorporate subsequent feedback for improvement;
- participate in the ONWAR PhD training program;
- assist in teaching program at UvA and supervise Bachelor and Master theses and tutoring students.
You will get the opportunity to - combine the advantages of a truly collaborative project, including access to the 3 different
state-of-the art research facilities at the UvA, TNO and NIN partners;
- publish your work in international journals, leading to a PhD thesis and present your
results at (inter)national scientific meetings;
- develop and expand you academic, professional, personal and soft skill set,
needed to become an independent scientist.
