"The glymphatic system and its role in Alzheimer's disease"
Docent Iben Lundgaard, Lunds universitet, Institutionen för experimentell medicinsk vetenskap, Glia-Immune Interactions
Dr. Lundgaard’s research has been focused on the role of glia in brain tissue homeostasis and metabolite clearance for the past 9 years. While working at University of Cambridge she discovered how growth factors in combination with neuronal activity control myelination and that remyelination is dependent on neurotransmitter receptors on the pre-myelinating oligodendrocytes. More recently her work has focussed on the brain wide glia-lymphatic pathway, also known as the glymphatic system. Briefly, instead of a conventional lymphatic system, the brain uses the perivascular spaces (between blood vessels and astrocytes’ endfeet). In the perivascular spaces cerebrospinal fluid (CSF) can exchange solutes with interstitial fluid in order to flush out metabolites and waste products. Interestingly, this pathway is highly active during sleep and shuts down in the wake state. While working with Maiken Nedergaard in Rochester, NY, Dr. Lundgaard applied this model to understand the glymphatic system as a delivery mechanism for small compounds such as glucose from CSF to brain tissue. She also researched this clearance system in relation to neurodegenerative diseases. Due to its function in brain clearance, it is important to gain a deeper understanding of the glymphatic system to develop new drugs or therapies for neurodegenerative diseases.
