PATHOGENESIS OF AMYOTROPHIC LATERAL SCLEROSIS
Department of Neurology, Medical University of Warsaw, Warsaw, Poland
Amyotrophic lateral sclerosis is a devastating neurodegenerative disease affecting both upper and lower motor neuron. Despiteextensive research the primary cause of the disease has not been indentified and the causative treatment is lacking. The present article describes mechanisms involved in the disease development and progression, including oxidative stress, excitotoxicity, mitochondrial dysfunction, protein aggregation, RNA processing, alterations of cytoskeleton functions and axonal transport, glial cell involvement and programmed cell death.
Biomed Rev 2011; 22: 7-14.
Key words: apoptosis, axonal transport, glial cells, glutamate excitoxicity, mitochondrial dysfunction, oxidative stress, superoxide dismutase
