Gene Therapy for Alzheimer's Preserves Brain Function

In a groundbreaking study recently published in Signal Transduction and Targeted Therapy, a team led by Brian Head, M.D., and Shanshan Wang, M.D. Ph.D., has unveiled a new gene therapy with the potential to revolutionize the treatment of neurodegenerative diseases. This innovative approach, which has been licensed to Eikonoklastes Therapeutics, could be a game-changer in the fight against conditions such as Alzheimer’s and Amyotrophic Lateral Sclerosis (ALS), even earning FDA Orphan Drug Designation for its potential applications in treating Lou Gehrig’s disease.

Unlike the current set of palliative options, which target the symptoms and effects of these diseases, this novel gene therapy goes to the root; it reprograms the behavior of brain cells, potentially slowing cognitive decline and preserving brain function in Alzheimer’s patients.

The collaboration between UC San Diego and Eikonoklastes Therapeutics represents a significant stride forward in the field of gene therapy for neurodegenerative disorders. The alliance marries San Diego’s academic expertise with Eikonoklastes’ commercial biotech acumen, exemplifying the growing trend of academia-industry partnerships aimed at accelerating the translation of bench-side discoveries into bedside applications.

The gene therapy technology has already shown compelling results in the treatment of ALS. The application of this technology to Alzheimer’s disease is an exciting development that could potentially open up a new frontier in targeted therapies. This approach is particularly relevant given the rising global burden of Alzheimer’s disease – a condition that currently affects millions worldwide, with numbers projected to increase in line with an ageing population.

A key aspect of this gene therapy is its focus on preserving hippocampal-dependent memory, a crucial facet of cognitive function that often deteriorates in Alzheimer’s patients. In mouse models, the team found that administering the therapy at a symptomatic stage of the disease led to the preservation of this type of memory. Remarkably, the treated mice also exhibited gene expression patterns similar to those of their healthy counterparts, indicating the therapy’s potential to revert diseased cells back to a healthier state.

While the translation of these promising results to human clinical trials requires further rigor and validation, the potential of this gene therapy cannot be overemphasized. This approach could herald a paradigm shift in neurodegenerative disease treatment, moving away from symptom management towards addressing the root causes. If successful, it could redefine the treatment landscape for neurodegenerative conditions, offering hope to millions of patients and their families worldwide.
