Transgenic rodent models of Parkinson's disease.

ABSTRACT: In the case of Parkinson's disease (PD), classical animal models have utilized dopaminergic neurotoxins such as 6-hydroxydopamine (6OHDA) and 1-methyl 4-phenyl 1,2,3,6-tetrahydropyridine (MPTP). More recently, human genetic linkage studies have identified several genes in familial forms of PD. Transgenic models have been made that explore the function of PD-linked genes (e.g. alpha-synuclein, DJ-1, LRRK2, Parkin, UCH-L1, PINK1). Recent evidence suggests mitochondrial dysfunction may play a major role in PD. Manipulation of mitochondrial respiratory genes (e.g. mitochondrial transcription factor A or TFAM) also elicits a PD phenotype in mice. Transgenic mice (MitoPark) were developed that have TFAM selectively knocked out in dopaminergic neurons. The nigral dopamine neurons of MitoPark mice
