Main areas of research: signal pathways in the brain, synapses, membrane molecules, brain volume regulation, development of neurodegenerative diseases
Ole Petter Ottersen is a neuroscientist. His research focuses mainly on signal molecules and synaptic transmissions in the brain. He clarified the function of membrane molecules in the brain, an accomplishment that could serve as the starting point for the development of new medicines.
Ole Petter Ottersen investigated how plasma membranes in the brain deal with water, which is an important question in connection with brain volume. He was able to explain the role of Aquaporin-4 (AQP4), which is the most prevalent membrane molecule in the brain. It is very widespread in the boundary areas (interfaces) of the blood brain barrier and the spinal fluid brain barrier.
He was able to show that AQP4 is involved in functions like the regulation of the volume of extracellular space, potassium buffering, interstitial fluid resorption, neuroinflammation, cell migration and calcium signalling. AQP4 is also necessary for the trouble-free functioning of the retina of the eye and the inner ear. Additionally, this molecule is involved in the processes associated with the development of neurodegenerative diseases. Targeted treatments could be aimed at the AQP4 membrane molecule.
