6-Hydroxydopamine (6-OHDA), a synthetic neurotoxin, has been used to generate animal models of Parkinson's disease (PD). Even though 6-OHDA induced neurodegenerative model in rat, it does not reproduce all the symptoms of the disease, but it does replicate most of the cellular processes such as oxidative stress, neurodegeneration, neuroinflammation and apoptotic neuronal death. The knowledge of the mechanisms involved in neurodegeneration is relevant to define possible therapeutic targets for PD.
