The Immp2l mutation causes age-dependent degeneration of cerebellar granule neurons prevented by antioxidant treatment.

Abstract excerpt

Reactive oxygen species are implicated in age-associated neurodegeneration, although direct in vivo evidence is lacking. We recently showed that mice with a mutation in the Inner Mitochondrial Membrane Peptidase 2-like (Immp2l) gene had elevated levels of mitochondrial superoxide, impaired fertility and age-associated phenotypes, including kyphosis and ataxia. Here we show that ataxia and cerebellar hypoplasia...
