An inducible MAO-B mouse model of Parkinson's disease: a tool towards better understanding basic disease mechanisms and developing novel therapeutics.

ABSTRACT

Several studies have suggested that increases in astrocytic monoamine oxidase B (MAO-B) levels in conjunction with Parkinson's disease (PD) may contribute to subsequent neuropathology associated with the disorder. MAO-B inhibitors are currently widely used as symptomatic therapeutics for PD and, although somewhat controversial, these drugs may also exhibit disease-modifying properties. To obtain a better understanding of the potential role of MAO-B in disease neuropathology, we created an inducible astrocyte-specific transgenic MAO-B mouse model. Here, we summarize findings associated with this model, including neuropathological PD features associated with it.
