'Trigger' for stress processes discovered in the brain

At the Center for Brain Research at the MedUni Vienna an important factor for stress has been identified in collaboration with the Karolinska Institutet in Stockholm (Sweden). This is the protein secretagogin that plays an important role in the release of the stress hormone CRH and which only then enables stress processes in the brain to be transmitted to the pituitary gland and then onwards to the organs. A current study on this molecular switch has now been published in the top-ranked EMBO Journal.

“If, however, the presence of secretagogin, a calcium-binding protein, is suppressed, then CRH (= Corticotropin Releasing Hormone) might not be released in the hypothalamus of the brain thus preventing the triggering of hormonal responses to stress in the body,” explains Tibor Harkany of the Department of Molecular Neurosciences at the MedUni Vienna.

The hypothalamus requires the assistance of CRH to stimulate the production and release…
