[Pathogenic mechanisms of neurodegenerative diseases: amyotrophic lateral sclerosis].
Since its description by Charcot in 1869, the mechanism underlying the characteristic selective degeneration and death of motor neurons in amyotrophic lateral sclerosis (ALS) has remained a mystery. There is no effective remedy for this progressive, fatal disorder. Modern genetics have now identified two genes, SODI and ALS2 as primary causes of the disease and has implicated others as potential contributors. These insights have enabled development of model systems to test hypotheses of disease mechanism and potential therapies. Along with errors in the handling of synaptic glutamate and the potential excitotoxic response that it provokes, these model systems underscore the involvement of non-neuronal cells in disease progression and provide new therapeutic strategies.
