Our research relies in the hypothesis that brain dysmetabolism is an underlying cause of neurodegenerative diseases such as Parkinson’s or Alzheimer’s.
Epidemiological findings suggest that Diabetes mellitus type 2 is an important risk factor for neurodegenerative diseases. The DysBrainD is focused in dissecting the molecular links between these diseases, to unveil novel causes for Neurodegenerative diseases.
We are currently investigating how glycation, reaction between sugars and biomolecules, is affecting the brain at a protein level (proteomics), all way to how it affects animal models (rodents) behaviour (motor and non-motor).
We are also investigating how sugar stress potentiates neurodegeneration and if compensating dysregulated proteins such as the insulin-degrading enzyme have therapeutic potential for Parkinson's disease.
The DysBrainD employs a translational approach from cells and animal models, to patient-derived cells and to the evaluation of Patient cohorts, aiming to identify novel biomarkers and disease-altering therapeutics for neurodegenerative diseases, particularly, for Parkinson's disease.
