Parkinson's disease (PD) is a progressive and chronic neurodegenerative disorder, characterized by progressive loss of dopaminergic neurons in substantia nigra. The etiology and pathogenesis of PD is still elusive, however, a large body of evidence suggests a prominent role of oxidative stress, inflammation, apoptosis, mitochondrial dysfunction and proteosomal dysfunction in the pathogenesis of PD. Due to multifactorial nature of the disease, currently available drug therapy cannot halt / slow down the disease progression, and only provides symptomatic relief. Peroxisome proliferator-activated receptor (PPAR), a member of nuclear receptor superfamily, regulates development, tissue differentiation, inflammation, mitochondrial function, wound healing, lipid metabolism and glucose metabolism. Recently, several PPAR agonists were shown to exert neuroprotective activity against oxidative damage, inflammation and apoptosis in several neurodegenerative disorders including Alzheimer's, Parkinson's, Huntington's, amyotrophic lateral sclerosis and multiple sclerosis. Similarly, regular intake of PPAR activating non-steroidal anti-inflammatory drugs such as indomethacin and ibuprofen was associated with reduced incidence and progression of neurodegenerative disorders in several epidemiological studies. In this article, we review studies relating to the neuroprotective effect of PPAR agonists in in vitro and in vivo models of PD. Similarly, the pharmacological mechanism in neuroprotective actions of PPAR agonists is also reviewed. In conclusion, PPAR agonists exert neuroprotective actions by regulating the expression of a set of genes involved in cell survival processes, and could be a therapeutic target in debilitating neurodegenerative illnesses such as PD.
