Development and regeneration

It is important to understand development in order to understand neurodegenerative disease and regeneration of the nervous system. Our research focuses on neural and glial development. We are especially interested in neuron-glia communication and the molecules used by the different cells to understand each other when differentiating and growing. The research we carry out is mostly based on primary cell cultures of glia and neurons from both the central nervous system (CNS) and the peripheral nervous system (PNS). In the cultures it is possible to investigate different aspects of communication, such as proliferation, migration, axon and dendrite elongation, synapse formation and myelination, using different molecular methods. Current projects:

1. GABA and GABA B receptors in glial development: We are currently investigating the role of GABA and its receptors in the PNS. We have found that GABA is generated by the neurons, and Schwann cells of the PNS and that GABA acting via its B-receptors may be essential for myelination in the nervous system. The project is a collaboration with Drs. Mikael Corell, Grzegorz Wicher and Robert Fredriksson at Uppsala University, Sweden, Duygu Daglikoca, Bogazici University, Turkey, Valerio Magnaghi and Eirikur Benedikz from SDU.

2. Nerve regeneration in the adult PNS: Every day people are involved in accidents that cause nerve damage. Nerve injuries to the peripheral nervous system (arms and legs) are the most common type of nerve injury. The existing procedure used to repair such injuries are not sufficient since only about 40% of the patients regain some movement and sensation in the injured limb. Together with hand surgeons, neurologists and material scientists (from Denmark and Sweden) we are currently working on a new and better method to improve the healing of such injuries. My group work with Schwann cells, essential glial cells, needed for the regeneration process. The work includes understanding how the glial cells react after injury, how we can make the patients own cells proliferate enough and how the cells will work together with axons and new biomaterials used for the healing. Active partners: Professors Søren Overgaard and Zsolt Illes Odense University Hospital (OUH), Denmark, Dr. Anders Lorentsen, OuH, Denmark, Dr. Ole Vilholm, Vejle Sygehus, Sygehus Lillebælt, Professor Lars Dahlin Lund University, Skåne University Hospital, Sweden, Professor Jöns Hilborn, Uppsala University Sweden

3. The role of MIF in glial development: It has recently been discovered that the protein Macrophage Migration Inhibitory Factor (MIF) is up-regulated in several neurological diseases such as multiple sclerosis, but also in stroke and nerve injury. The function of MIF in the nervous system is not clear. We have found that in particular glial cells express MIF and that the expression varies during development. We are currently working to better understand what MIF does in glia during development, to get a better idea of what it does in neurodegenerative disease. This is done first by investigating the over all expression of MIF in the nervous system, during development. Finding new binding partners to MIF to understand what cell signaling MIF is involved in and finally to block or overexpress the function of MIF in cells and animals. This work is a collaboration with Dr. Malin Andersson, University of Uppsala, Sweden and Eirikur Benedikz at SDU.
