title: Six important themes in amyotrophic lateral sclerosis (ALS) research, 1999.
abstract: My assignment was to identify the 6 most important ALS papers published in 1999 but, great to relate, there were too many excellent candidates. Rather than confining the search to individual papers, six major themes seemed appropriate for discussion: 1) The study of transgenic mice that carry a mutated human gene for superoxide dismutase-1 (SOD1) has led to many far-reaching advances in ALS research. The mice are regarded as the best test system to evaluate potential therapies, including creatine. Inconsistencies between efficacy in mice and people are noted, however. 2) Transgenic mice have also been used to evaluate the role of glutamate toxicity in the pathogenesis of ALS, a dominant theory. 3) The role of mitochondria in the pathogenesis of ALS is gathering increasing attention. 4) The role of neurofilaments in the pathogenesis of ALS has provided new twists in mice and people. 5) Motor neuropathy is the most important differential diagnosis of ALS. 6) Gene therapy, as exemplified by the use of stem cells, has been applied successfully to animal models of other inherited diseases of the central nervous system.
