Here we report that intragastrically administered rotenone, a commonly used pesticide that inhibits mitochondrial Complex I, is able to reproduce PD pathological staging as found in patients. Our results show that low doses of chronically and intragastrically administered rotenone induce PD pathology in all the above-mentioned nervous system structures in wild-type mice. Interestingly, HPLC analysis showed no rotenone levels in the systemic blood or the central nervous system (CNS) (detection limit [rotenone] http://precedings.nature.com/documents/3352/version/2 Mon, 22 Jun 2009 20:13:49 UTC Progression of Parkinson’s disease pathology is reproduced by intragastric administration of rotenone in mice hdl:10101/npre.2009.3352.2 2009-06-22 Francisco J.
