New Research on ALS: Advances Toward a Possible Cure

Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease that has challenged science for decades. However, an innovative study conducted by the Biogipuzkoa Health Research Institute has opened new doors in the understanding and treatment of this disease, highlighting the crucial role of muscle tissue in its development. This breakthrough has the potential to change the current approach to treatment and offer new hope to those living with the condition.

The study led by the Biogipuzkoa Institute emphasizes a novel aspect: muscle tissue. Traditionally, ALS has been considered a disease affecting motor neurons, the cells responsible for transmitting signals to the muscle. However, scientists at the institute have discovered that skeletal muscle may be much more than a simple recipient of damage. According to Dr. Adolfo López de Munain, head of the study, muscle may play an active role in the development of the disease. This new perspective suggests that, in some cases, muscle damage might not only be a consequence of motor neuron degeneration, but could also influence its progression in a retrograde manner, affecting the motor neuron itself.

The research team at the Biogipuzkoa Health Research Institute has worked on this multidisciplinary approach, combining the expertise of specialists in neurodegeneration, genetics, and muscle disorders. This allows for the exploration of ALS’s multicausality and overcomes the limitations of one-dimensional approaches that focus on a single factor or cause. According to experts, the variability in how the disease presents in patients indicates that treatments must be adapted to the diversity of contributing factors.

The relationship between muscle activity and ALS

One of the recurring topics in ALS research is the relationship between intense physical activity and the onset of the disease. Although it cannot be said that high-intensity exercise is a direct cause, it has been observed that in some ALS cases—such as those involving professional football players—there may be a correlation with significantly increased muscle activity. Dr. Sonia Alonso, a member of the research team, suggests that ALS could have a metabolic origin related to excessive muscle wear. The disease is hypercatabolic, meaning it rapidly consumes the body’s energy, and this accelerated wear could be one of the contributing factors to ALS development in genetically predisposed individuals.

Additionally, neurologist Juan José Poza emphasizes that although there have been case reports involving athletes—such as footballers from the Italian league in the 1970s—there is no proven link between muscle activity alone and ALS. However, research is ongoing to determine which factors, in combination with genetic predisposition and other elements, may underlie the onset of this disease.

A major scientific breakthrough

This study, published in the prestigious journal Acta Neuropathologica, represents a significant step forward in ALS science. The work carried out by researchers at the Biogipuzkoa Institute not only provides a new perspective on the role of muscle tissue, but also promotes the idea that future ALS therapies should adopt a comprehensive approach that integrates multiple factors and research areas.

The contributions of Adolfo López de Munain, Patxi Gil, Gorka Guereñu, Lorea Blázquez, Sonia Alonso, and many other team members have been essential in advancing this line of research. While there is still no effective treatment to stop the progression of the disease, these developments could be key to creating more targeted therapies suited to the diverse manifestations of ALS. Research continues, and each step taken brings us closer to offering new solutions for those who suffer from this devastating disease.

In conclusion, the renewed focus on muscle tissue and its role in ALS opens new avenues for treating the disease. With the collaboration of experts across disciplines and the publication of relevant findings, science is gradually moving closer to discovering effective treatments that could relieve—or even eliminate—this neurodegenerative condition.
