Amyotrophic lateral sclerosis (ALS) is a complex neurodegenerative disease that primarily affects motor neurons, leading to progressive muscle weakness and paralysis. While most cases of ALS have unknown causes, mutations in the Cu/Zn superoxide dismutase (SOD1) gene account for a small percentage of instances.
The pathology of ALS involves a combination of factors such as protein misfolding, mitochondrial dysfunction, oxidative damage, and inflammation, among others. The selective vulnerability of motor neurons and the role of nonneuronal cells in accelerating disease progression highlight the complexity of ALS.
Research on mutant SOD1 models provides hope for developing effective therapies that could potentially translate to sporadic ALS cases. By targeting nonneuronal cells and understanding the underlying mechanisms of motor neuron damage, scientists aim to uncover new treatment options for ALS patients.
