Brief description of research activities

At the Department of Neuroscience and Pharmacology at the University of Copenhagen, the Laboratory of Translational Neurobiology (LTN) aims to understand how the brain controls its own blood supply and use, and the transport of molecules across the blood-brain-barrier. The new knowledge generated in the lab can be used to understand the general pathophysiology of a number of human brain diseases and conditions including ageing, stroke, migraine and intracerebral and subarachnoid hemorrhage.

Important milestones at the Laboratory of Translational Neurobiology
Among others the LTN has achieved the following milestones:
• Implementation of two-photon microscopy for use in living rodents
• Implementation of optogenetics for use in living rodents
• Implementation of genetically encoded indicators for assessment of nerve cell activity by 2-photon microscope
• Generation of mouse models for ageing, migraine, stroke and brain hemorrhages
• Novel findings about vascular control by calcium signals in the neurovascular unit and in brain vascular pericytes was published recently.

The LTN takes part in and are leading the Lundbeck Foundation Research Initiative on Brain Barriers and Drug Delivery (RIBBDD) and has developed new models to assess drug delivery to the brain.

Network and collaborators at the Laboratory of Translational Neurobiology
The group has ongoing collaboration with researchers including, but not limited to, University of British Columbia, Vancouver, Canada; the MIRCen, Paris, France; Moscow State University with Klinikum Charite, Berlin, Germany, and with scientists at national universities.
