Amyotrophic lateral sclerosis (ALS) is a life-threatening neurodegenerative disease for which there are currently no effective treatments. Current research efforts are often address protein deregulation as a contributing factor. Our proposal is to examine the environment of motor neurons in greater detail to determine how this contributes to the disease, with a specific focus on a subtype of cellular senescence.
Senescence is a state that cells can enter when they become irreparably damaged. Senescent cells secrete factors into their environment that can lead to chronic disruption of cell-to-cell communication. Recent evidence in mice has shown that senescent cells can drive cognitive decline, neuroinflammation and neurodegeneration. Our preliminary research has also identified the presence of senescent cells in TDP43 mutant mice. Understanding and counteracting the potentially deleterious role of senescent cells in the environment may therefore be attractive against ALS.
You will investigate whether the removal of scarred-senescent cells can affect motor neuron health and function in 2D and 3D tissue culture, assess the role potential candidates advanced multiplex techniques (4i, Cy-Chi and CosMX) and whether disease features can be stalled or counteracted in neurodegeneration/aging/ALS mouse models. When successful and the elimination of scarred senescent cells delays or counteracts disease-features associated in mice, this innovative strategy could then progress into clinical translation aimed at improving the quality of life and survival of patients.
Utrecht University and its Medical Center house well over 6000 researchers and consistently delivers top-notch research in biology and medicine, evident from a solid ranking among the absolute top academic centers in Europe. The UMCU is one of the leading centers for Cancer research in the Netherlands, well-renowned for its capacity to translate fundamental breakthroughs in oncology research to experimental treatment of patients.
The Center for Molecular Medicine houses experts and state-of-the-art facilities for a broad range of techniques, including genomics (next-generation DNA sequencing, metabolomics, proteomics), cell culturing (iPS cells, organoids), microscopy (live cell imaging, electron microscopy) and bioinformatics (high-performance computing).
Peter de Keizer is associate professor in "Senescence in Cancer and Aging". His research has been highlighted in numerous national and international media items. His aim is to unravel the molecular mechanisms that cause cells to become senescent and to identify how these cells drive aging and age-related diseases. The role of senescence in late-stage therapy-resistant cancer is a major component of this research. The research has a strong translational component and a spearpoint of the group is to develop methods to target the deleterious effects of senescent and senescent-like cancer cells, for instance by eliminating them altogether.
This 3-year postdoctoral fellowship is focused on molecular mechanisms in ALS (Amyotrophic Lateral Sclerosis) - especially involving mouse models and iPSC-derived co-culture systems. Applicants interested in this project should meet the following requirements:

Wij geloven in de kracht van een divers team waarin ruimte is voor verschillende vaardigheden, expertises, sociale en culturele achtergronden. Wij zijn benieuwd naar jou!
Onze nieuwe collega's werven we zelf. We hebben geen behoefte aan acquisitie.
