Brief description of research activities

The group started its research path on 2006, since then, they have focused their research on the neurodegenerative process in Parkinsonís disease and other alpha-synucleinopathies.
The team has during the last years studied and characterized those pathological events initiated as a consequence of the overexpression and or mishandling of the protein alpha-synuclein that contribute to the disease process. In addition, they have an interest on the processes occurring in the immune system during the neurodegenerative event and how both, local and peripheral immune cells, can modify the neuronal survival. Their fundamental goal is to reveal new targets for disease modification that can be ultimately used to develop novel therapies for the patients.
The lab's main tools of work are animal models of the disease: from neurotoxin based models to transgenic models, both classic transgenic mouse lines and adult transgenesis models by means of viral vectors. We are also using the fibril alpha-synuclein spreading model.
