Heidelberg Researchers Identify Neuron Survival Programmes

New experiments at the University of Heidelberg's Institute of Neurobiology provide deeper insights into the complex functioning of the brain. In their study, the neurobiologists headed by Prof. Hilmar Bading, together with scientists from the German Cancer Research Centre and the University of Geneva, investigate one of the central molecular switches in the brain, the so-called NMDA receptor. These receptors are of crucial significance as they control learning and memory processes and can either strengthen the survival capacity of nerve cells or cause neuronal degeneration and cell death.

Prof. Bading's research group has now deciphered the contradictory behaviour of the NMDA receptor at the genetic level. Over 40,000 different genes were analysed using gene chip technology. The results indicated that NMDA receptors control different genetic programmes depending on their location on the surface of cells. These programmes either strengthen the survival capacity of nerve cells or lead to cell death. The researchers were able to demonstrate a nerve-protection function for a series of new genes. The identification of the NMDA receptor-controlled survival programme opens up new prospects for therapeutic approaches in the treatment of neurodegenerative disorders like Alzheimer's disease or Parkinson's disease.
