Abstract:

Parkinson’s disease (PD) is a progressive neurodegenerative disorder that occurs mainly due to the degeneration of dopaminergic neuronal cells in the substantia nigra. l-3,4-Dihydroxyphenylalanine (l-DOPA) is the most effective known therapy for PD. However, chronic l-DOPA administration results in a loss of drug efficacy and irreversible adverse effects, including l-DOPA-induced dyskinesia, affective disorders, and cognitive function disorders. To study the motor and non-motor symptomatic dysfunctions in PD, neurotoxin and genetic animal models of PD have been widely applied. However, these animal models do not exhibit all of the pathophysiological symptoms of PD. Regardless, neurotoxin rat and mouse models of PD have been commonly used in the development of bioactive components from natural herbal medicines. Here, the main animal models of PD and their applications have been introduced in order to aid the development of therapeutic and adjuvant agents.
