Neurodegenerative Diseases

The research conducted in our group is geared toward elucidating the cause and molecular mechanisms of neurodegeneration in Parkinson's disease (PD), a disabling, currently incurable common neurodegenerative disorder. To this end, we perform clinical and pre-clinical translational research in both PD patients and in human-relevant experimental in vitro and in vivo PD-related models. 

Elucidating the molecular mechanisms underlying neurodegeneration in PD should allow to: 

  • Identify biomarkers for PD diagnosis, early detection, patient stratification, disease progression, prognosis or response to treatment. This is the objective of the VHIP Project that the team is carrying out.
  • Identify new molecular targets for potential therapeutic intervention and prevention.
  • Develop novel therapeutic strategies with disease-modifying potential.
  • Unravel molecular pathways common to other neurodegenerative diseases and, in a broader sense, brain aging.

Regeneration of dopaminergic neurons in Parkinson's disease via cell fusion-mediated reprogramming

Co-PI: Pia Cosma, CRG.


Given the current lack of disease-modifying therapies for Parkinson’s disease (PD), we are exploring whether cell-fusion-mediated regeneration of dopaminergic neurons can be achieved, for therapeutic purposes, in experimental animal models of PD after transplantation of Wnt-activated haematopoietic stem and progenitor cells (HSPCs).

Role of autophagy in neurodegeneration

The main focus of our research is to study the role of autophagy in neurodegeneration.

Autophagy is the degradation of intracellular components inside the lysosomes and it is essential for the maintenance of cellular homeostasis and neuronal viability. Alterations in the autophagy process have been associated with neurodegenerative diseases including Parkinson’s, Huntington’s and Alzheimer’s disease,  and has been shown to be one of the main causes that contribute to neuronal death in these pathologies.

 

Our efforts are currently directed to:

- Study the pathogenic role of autophagic/lysosomal dysfunction in Parkinson's disease

- Development of new therapies for Parkinson’s disease based in the restoration of lysosomal glucocerebrosidase (GBA) activity through nanoencapsulation.

- Development of new autophagy pharmacological modulators (mTOR-independent) as a therapeutic strategy in neurodegenerative diseases.

- Study  selective autophagy in Huntington’s disease: charaterization of mitophagy impairment in Huntington’s disease.

Role of mitochondria in Parkinson's disease

Mitochondria are highly dynamic organelles with complex structural features that play several important cellular functions, such as the production of energy by oxidative phosphorylation, the regulation of calcium homeostasis, or the control of programmed cell death. Given its essential role in neuronal viability, alterations in mitochondrial biology can lead to neuron dysfunction and cell death. Defects in mitochondrial respiration have long been implicated in the etiology and pathogenesis of Parkinson's disease (PD). However, the role of mitochondria in PD extends well beyond defective respiration and also involves perturbations in mitochondrial dynamics, leading to alterations in mitochondrial morphology, intracellular trafficking, or quality control. Whether a primary or secondary event, mitochondrial dysfunction holds promise as a potential therapeutic target to halt the progression of dopaminergic neurodegeneration in PD.

Coneix i participa al projecte VHIP

Vall d'Hebron Iniciativa per al Parkinson (VHIP) is a research project aimed at the development of biochemical markers for the early detection of Parkinson's disease. This study is carried out in people at high risk of having this disease, because they carry genetic mutations that predispose to the development of Parkinson's or because they present non-motor symptoms that manifest themselves years before motor symptoms.
