Barcelona, Spain (AP) — Gene therapy has demonstrated the potential to restore motor skills in animal models of megalencephalic leukoencephalopathy with subcortical cysts (MLC), a rare neurological disease, according to a recent study. Researchers at the Autonomous University of Barcelona (UAB) found that the therapy was effective even after symptoms had already appeared.
Understanding Megalencephalic Leukoencephalopathy with Subcortical Cysts (MLC)
MLC is a rare childhood neurological disorder primarily affecting the brain’s white matter. Key characteristics include macrocephaly, impaired motor coordination, and epilepsy.
Mutations in the MLC1 gene are responsible for over 75% of diagnosed MLC cases. This gene encodes a protein located in the astrocyte membrane, a type of brain cell.While the protein’s precise function remains under investigation, it is indeed known to play a critical role in regulating water and ion balance within the brain.
Gene Therapy Approach
The research team, led by Assumpció Bosch at the UAB’s Department of Molecular Biochemistry and Biology and the Institute of Neurosciences (INC-UAB), used a viral vector to deliver a healthy copy of the MLC1 gene to an animal model with the condition. The goal was to restore normal protein activity.
The study, published in Molecular Therapy, showed the treatment’s effectiveness. Gene expression was sustained in the brain for a year, normalizing physiological changes and reversing motor deficits in the treated mice.
Alejandro Brao, a researcher in the Department of Molecular Biochemistry and Biology and the led author of the study, said the findings suggest gene therapy could be effective even in advanced stages of the disease.
Future Research Directions
Assumpció Bosch, study coordinator, said the next steps involve identifying the most suitable gene vector for clinical request, determining the minimum effective dose, and conducting biological safety and biodistribution studies in larger animal models.
Our next steps will aim to identify the most suitable gene vector for clinical application, determining the effective minimum dose and carrying out biological safety and biodistribution studies on larger animal models.

The research offers new therapeutic possibilities for MLC patients and underscores the potential of gene therapy for treating rare neurological diseases by restoring the expression of affected genes.
Gene Therapy for megalencephalic Leukoencephalopathy with Subcortical Cysts (MLC): Your Questions Answered
Are you curious about a potential breakthrough in treating a rare neurological disorder? This Q&A-style blog post will explore a recent study on gene therapy for Megalencephalic Leukoencephalopathy with Subcortical Cysts (MLC). We’ll delve into the details, using data from a recent study from the Autonomous university of Barcelona (UAB). Let’s dive in!
What is Megalencephalic Leukoencephalopathy with Subcortical cysts (MLC)?
MLC is a rare genetic disorder affecting the brain, specifically the white matter. It primarily affects children.
What are the key characteristics or symptoms of MLC?
The primary characteristics of MLC include:
Macrocephaly: Abnormally large head size.
Impaired motor coordination: Difficulty with movement and balance.
Epilepsy: Seizures.
What causes MLC?
MLC is caused by mutations in the MLC1 gene. These mutations are responsible for over 75% of diagnosed cases.
What does the MLC1 gene do?
The MLC1 gene provides instructions for creating a protein found in the membrane of astrocytes,which are a type of brain cell. While the exact function of this protein is still under investigation, it plays a critical role in maintaining the proper water and ion balance within the brain.
What is gene therapy,and how is it being used to treat MLC?
Gene therapy aims to treat diseases by correcting or replacing faulty genes.In the context of MLC, researchers are using gene therapy to deliver a healthy copy of the MLC1 gene to the brain cells of individuals affected by the disease.
How does the gene therapy work in this particular study?
The research team at UAB, led by Assumpció bosch, used a viral vector to carry a healthy copy of the MLC1 gene. This vector was delivered to an animal model with MLC. the goal was to restore the normal activity of the protein encoded by the MLC1 gene.
What were the main findings of the study?
The study, published in Molecular Therapy, showed that the gene therapy was effective in animal models:
Motor skills restoration: The therapy improved motor skills.
Sustained gene expression: The healthy gene expression continued in the brain for an entire year after treatment.
Reversal of deficits: The treatment reversed motor deficits in the treated mice.
Can gene therapy be effective even after symptoms have appeared?
Yes, the study’s findings suggest that gene therapy could be effective even in the advanced stages of the disease, as stated by the lead author, Alejandro Brao.
What are the next steps in this research?
The researchers are planning several follow-up steps, including:
Identifying the most suitable gene vector for clinical application.
Determining the minimum effective dose for the therapy.
Conducting biological safety and biodistribution studies in larger animal models.
What is the significance of this research for MLC patients?
This research offers hope for new therapeutic possibilities for individuals with MLC. It highlights the potential of gene therapy to treat other rare neurological conditions by restoring the function of affected genes.
What are the potential benefits of this gene therapy approach?
| Benefit | Description |
| —————————- | ———————————————————————————————————– |
| Improved motor Skills | The therapy has demonstrated the potential to restore motor skills in animal models. |
| Sustained Gene Expression | The healthy gene expression was maintained in the brain for an extended period (one year in the study). |
| Reversal of Deficits | the treatment resulted in the reversal of motor deficits in the treated animals. |
| Potential for Advanced Stages | Research suggests potential effectiveness even when the disease is advanced. |
