Neurons’ Broken Machinery Piles Up in ALS
NIH scientists identify a transport defect in a model of familial ALS
A healthy motor neuron needs to transport its damaged components from the nerve-muscle connection all the way back to the cell body in the spinal cord. If it cannot, the defective components pile up and the cell becomes sick and dies. Researchers at the National Institutes of Health’s National Institute of Neurological Disorders and Stroke (NINDS) have learned how a mutation in the gene for superoxide dismutase 1 (SOD1), which causes ALS, leads cells to accumulate damaged materials. The study, published in the journal Neuron, suggests a potential target for treating this familial form of ALS.
