In humans, stressful or traumatic life events such as death of a close relative often represent a chronic psychological load that can lead to central nervous diseases such as depression. We are investigating central nervous processes that occur in the course of chronic psychosocial stress in animals that show similar symptoms as depressed patients.
Changes in neurotransmitter systems, receptors, transporters and other molecules are investigated using molecular biology methods to quantify expression of genes in combination with in situ hybridization and immunocytochemistry to localize the changes in distinct neurons of the brain. The effects of antidepressants are investigated with the same tools to elucidate mechanisms that underlie the beneficial effects of these drugs. In conjunction with behavioral studies we are able to find neuromolecular factors that contribute to emotional behavior in the animals.
