Compensatory mechanism of motor defect in SOD1 transgenic mice by overactivation of striatal cholinergic neurons.

Abstract

Expression of a mutant superoxide dismutase 1 (SOD1) gene in transgenic mice induces a gradual degeneration of cholinergic motor neurons in the spinal cord, causing progressive muscle weakness and hindlimb paralysis. Transgenic mice over-expressing the human SOD1 gene containing a Gly-->Ala substitution at position 93 (G93A) were employed to explore the… (More)
