| General description: | 6-Hydroxydopamine hydrochloride (6-OHDA) is a neurotoxin, commonly used to induce Parkinson′s disease (PD). 6-OHDA causes death of dopaminergic neurons in substantia nigra pars compacta progressively mimicking PD. 6-OHDA is highly oxidizable and cannot cross blood brain barrier. 6-OHDA exerts cytotoxicity by generating reactive oxygen species, initiating cellular stress and cell death. 6-OHDA leads to neuronal cell death in many in vitro models like primary neuronal culture, human neuroblastoma cell line and rat adrenal pheochromocytoma cell line, PC12. |
