The PPAR-gamma agonist pioglitazone modulates inflammation and induces neuroprotection in parkinsonian monkeys

Journal of Neuroinflammation 2011, 8:91 doi:10.1186/1742-2094-8-91

Activation of the peroxisome proliferator-activated receptor gamma (PPAR-gamma) has been proposed as a possible neuroprotective strategy to slow down the progression of early Parkinson's disease (PD). Here we report preclinical data on the use of the PPAR-gamma agonist pioglitazone (Actos(R); Takeda Pharmaceuticals Ltd.) in a paradigm resembling early PD in nonhuman primates.

Clinically, pioglitazone has been tested for Alzheimer disease, multiple sclerosis, autism, stroke, amyotrophic lateral sclerosis, and Friedreich’s Ataxia. The results of these small clinical trials suggest that its administration can benefit patients with neurological disorders.

MDA has awarded a research grant to Des Richardson, professor and senior principal research fellow at the University of Sydney (Australia) to continued research into iron metabolism in Friedreich's ataxia (FA).

The aim of Richardson's studies is to examine the role of altered iron metabolism in the cellular energy factories called mitochondria.
