Pro-survival and anti-inflammatory roles of NF-κB c-Rel in the Parkinson's disease models.

ABSTRACT: The pathological hallmarks of Parkinson's disease (PD) are the progressive loss of dopaminergic (DA) neurons in the substantia nigra pars compacta (SNpc) and the presence of overactivated glial cells and neuroinflammation. Nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) c-Rel subunit is closely related in the pathological progress of PD, however the roles and mechanisms of c-Rel in PD development remain unclear. Here, in neurotoxins-induced PD models, the dynamic changes of NF-κB c-Rel and its functions were evaluated. We found that c-Rel was rapidly activated in the nigrostriatal pathway, which mainly occurred in dopaminergic neurons and microglia. c-Rel could maintain neuronal survival by initiating the anti-apoptotic gene expression in MPP⁺-treated SH-S
