"PROMOTING BRAIN REPAIR BY HARNESSING THE IMMUNE SYSTEM"


Our current research aims at elucidating how cellular lipid metabolism impacts inflammatory and repair processes within the central nervous system (CNS) with a focus on Multiple Sclerosis (MS).

During MS, macrophages infiltrate the brain and together with microglia, the resident immune cells of the CNS, degrade myelin, an insulating layer surrounding nerves that is important for the propagation of action potentials.  Myelin breakdown, also called demyelination, leads to failure of nerve conduction and to a wide range of clinical symptoms such as loss of vision and muscle weakness. Besides contributing to demyelination, macrophages and microglia can also promote repair of damaged tissue (remyelination) by clearing myelin debris and secreting anti-inflammatory and neurotrophic factors.

Myelin consists for the major part of lipids, such as cholesterol and fatty acids. In MS, a disturbed lipid metabolism is detected. However, little is known about the cause of this disturbance and the impact it has on disease progression. Our findings show that lipids present in myelin alter the function of macrophages and microglia. By targeting the underlying pathways a beneficial  macrophage phenotype can be induced that slows down lesion progression and stimulates repair. Interestingly, specific nutritional components impact lipid metabolism and immune cell function and thus provide a promising strategy to limit lesion progression and promote CNS repair. Current research focusses on further elucidating metabolic pathways that direct immune cell function and to translate current findings into therapeutic applications.

We aim to:

1) determine the role of cholesterol and fatty acids in CNS inflammation, demyelination and remyelination.

2) study how dietary components affect CNS lipid metabolism and the function of resident brain cells.

Dr. Jeroen Bogie

As a PhD student at Hasselt University, Jeroen Bogie defined the physiology of macrophages in multiple sclerosis (MS). He established thatmyelin-containing macrophages suppress autoreactive T cell proliferation andthat lipid-sensing nuclear receptors are key in driving the functionalproperties of macrophages in MS lesions. In 2014, he started a post-doctoralposition at Rotterdam University. Here, he assessed the impact of plant sterolson Alzheimer’s disease. In 2015, Jeroen obtained a FWO postdoctoral grant tocontinue on findings that emanated from his PhD project. Currently, he defines the impact of fatty acid metabolism on the functional properties of macrophagesand T cells in MS. 


Dr. Mansour Haidar

Mansour obtained an MSc in neuroscience from the University of Strasbourg in France, and a PhD in biochemistry and biotechnology from the University of Antwerp in Belgium. During his PhD he studied autophagy and proteostasis in neurodegeneration. He joined the group end of 2018 bringing with him this expertise to the field of neuroinflammation and macrophage metabolism.
