Nesfatin-1 and glucagon-like peptide-1(GLP-1) levels in Parkinson's disease and their effect on oxidative processes

Abstract

Parkinson's disease (PD) is a neurodegenerative disorder characterized by bradykinesia, tremor, rigidity, and postural instability which progress through the loss of dopaminergic neurons (1). Progressive loss of dopaminergic neurons at the substantia nigra pars compacta is responsible for the pathophysiology (2). Postmortem studies have shown the essential role of oxidative stress in neuronal degeneration of the dopaminergic nigral neurons (3). Recent reports describe nesfatin-1 and glucagon-like peptide-1 (GLP-1) as molecules with neuroprotective property that relieve oxidative stress. Here we aimed to determine the blood levels of nesfatin-1 and GLP-1 in PD and their effect on oxidative processes.
