- FKBP51 protein found in the muscle can promote diabetes and obesity in people who consume unhealthy diet
- An unhealthy diet, rich in fat can induce stress in the body and thereby increase the production of FKBP51 protein
- Increased production of FKBP51 protein can lead to changes in glucose absorption and intolerance leading to diabetes
Diabetes and obesity can now be promoted by a stress regulating protein called as FKBP51. This protein if not regulated can cause glucose intolerance in the body causing diabetes. The findings of this study are further discussed in the journal of Nature Communications.
For some time, researchers have known that the protein FKBP51 is associated with depression and anxiety disorders. It is involved in the regulation of the stress system - when the system does not function properly; mental disorders may develop.
Now, researchers at the Max Planck Institute of Psychiatry have discovered a new, surprising role for this protein: It acts as a molecular link between the stress regulatory system and metabolic processes in the body.
An unhealthy diet, rich in fat means stress for the body. If FKBP51 is increasingly produced in the muscle it leads to reduced absorption of glucose - as a result, diabetes and obesity may develop.
If FKBP51 is blocked, diabetes will not develop, even if too many calories are consumed or the body is still stressed. Less FKBP51 in the muscle tissue means reduced glucose intolerance and thus maintenance of normal metabolism.
The protein FKBP51 can be pharmacologically blocked by antagonist compounds that were developed at the Max Planck Institute by Felix Hausch (presently at University of Darmstadt).
In collaboration with the scientists at the Technical University Darmstadt and funded by the Bavarian State Ministry of Economic Affairs and Media, Energy and Technology, these compounds will be further developed for use in clinical trials.
"These findings may provide a completely new treatment approach for diabetes and other metabolic diseases," states Alon Chen, Director at the Max Planck Institute of Psychiatry.
