Gene Therapy Congenital Diseases with Neurological Affection
"Gene therapy could lastingly improve the lives of patients with monogenic diseases such as Dravet Syndrome."
DR. RUBÉN HERNÁNDEZ ALCOCEBA RESEARCHER. GENE THERAPY CONGENITAL DISEASES WITH NEUROLOGICAL AFFECTION RESEARCH GROUP
Genetic diseases with neurological involvement usually cause a progressive deterioration in the quality of life of patients, and currently lack specific treatments. In many cases they are due to mutations in genes essential for the correct functioning of neurons. However, these diseases can also be secondary to defects in liver metabolism that lead to the accumulation of neurotoxic substances.
The Gene Therapy Group of Congenital Diseases with Neurological Affection at Cima focuses on designing vectors adapted to this type of diseases, taking into account the characteristics of the affected gene and the organ where it exerts its main function. Our study is focused on the investigation of two diseases:
Dravet Syndrome (DS): congenital encephalopathy characterized by causing very severe epileptic seizures and progressive neurological deterioration.
Cerebrotendinous Xanthomatosis: neurodegenerative disease in which there is a defect in bile acid metabolism that causes the accumulation of neurotoxic intermediates and could be addressed by gene therapy targeting the liver.
Our multidisciplinary team works in close collaboration with other Cima research groups and platforms.

Objectives of our research
- Development of high-capacity adenoviral vectors (HC-Ads) and evaluation of the most appropriate regulatory sequences.
- Evaluation of these vectors in a mouse model designed by the Dravet Syndrome Foundation.
- Study of the use of vectors derived from adeno-associated viruses (AAV) that have shown safety and efficacy in several clinical trials.
- Functional evaluation of these vectors using mice deficient in the homologous gene, subjected to pharmacological treatments that allow mimicking the neurological pathology present in these patients.
FROM THE LABORATORY TO THE CLINIC
High capacity adenovirus
Our group is specialized in a type of vector called High Capacity Adenovirus (HC-Ad) which, contrary to previous versions, does not contain viral genes. This feature reduces their toxicity and confers them two important properties: the possibility of harboring extensive DNA sequences, and the maintenance of their function for long periods of time in vivo.
We have refined the production method of HC-Ad to achieve higher yield and purity, and have used them extensively for the controlled expression of genes with antitumor activity.
FROM THE LABORATORY TO THE PATIENT
Cutting-edge translational research
The research team of the Gene Therapy Program is fundamentally basic, but with a very translational vision and maintains close collaborations with teams from the Clínica Universidad de Navarra.
Improvement of therapies developed for genetic diseases and cancer to provide solutions for patients.
Transfer DNA or RNA in vivo
Implementation of new gene therapy technologies using gene editing or non-viral vectors.
Long non-coding RNAs (lncRNAs)
Development of new expression regulation systems, as well as the identification of new therapeutic targets.
