Michigan Lab Develops New Gene Therapy to Target ALS

A research team in Grand Rapids is bringing fresh hope to people living with ALS by developing therapies that could stop the disease at its source.

Amyotrophic lateral sclerosis destroys the nerve cells that control our muscles, making it progressively harder to move, eat, and breathe. For decades, doctors could only treat symptoms because the disease was too complex to understand. Now, Dr. Qiang Zhu and his team at Van Andel Institute are changing that.

The lab runs one of the only ALS research programs in West Michigan. They focus on a gene called C9ORF72, which causes the most common inherited form of ALS. In some people, this gene contains a glitch where DNA sequences repeat incorrectly. These repetitions create harmful protein buildups that slowly kill the nerve cells controlling muscle movement.

Traditional ALS treatments help patients manage their symptoms and maintain quality of life. But Zhu's team is taking a different approach. They're developing gene therapies that either repair the faulty genes directly or reduce the inflammation that makes the disease worse.

Only 10% of ALS cases run in families through inherited genes. The other 90% appear randomly, likely caused by a mix of genetic and environmental factors. This variation makes every case unique and treatments difficult to design.

The Ripple Effect

Gene therapy represents a turning point for ALS research because it tackles the disease's biological roots instead of just its effects. When treatments can stop nerve cells from dying in the first place, they preserve patients' ability to move and breathe independently for longer.

Zhu's lab is also creating new research tools that help scientists study ALS more precisely and test potential treatments faster. These innovations don't just help ALS patients. The techniques could speed up therapy development for other neurodegenerative diseases like Parkinson's and Alzheimer's.

The work matters because ALS remains an urgent medical challenge with limited options. Each breakthrough in understanding how genes trigger the disease opens new pathways for intervention. What starts as lab research today could become life-changing treatments within years.

Better treatments for the underlying causes of ALS could transform this devastating diagnosis into a manageable condition.
