New miniaturized model of neuromuscular junction formation provides insight into ALS

New miniaturized model of neuromuscular junction formation provides insight into ALS Skeletal muscles enable voluntary movements and are controlled by a special type of neurons called motor neurons, which make direct contact with skeletal muscles through so-called neuromuscular junctions (NMJs). It is through NMJs that skeletal muscles receive signals making them contract or relax. In certain neurodegenerative diseases, such as amyotrophic lateral sclerosis (ALS), NMJs are destroyed, leading to progressive muscle weakness and ultimately death. Treatments for ALS mainly focus on alleviating symptoms but cannot stop or reverse its disease progression. To find more effective treatments, researchers require accurate and easily accessible lab-based models for ALS to understand its causes and to develop and test new therapies.
