The proinflammatory cytokines, IL-1β and TNF-α, are known to play a key role in inflammatory reaction in many forms of acute and chronic neurological diseases. In Parkinson’s disease (PD), those cytokines immunoreactivity was significantly increased in the substantia nigra and striatum. Moreover, it is implicated that the production of those cytokines from activated microglial cells in Parkinson’s brain contributes to the increase of pathological oxidative stress. However, it is not clear what is the molecular mechanism of cytokines-related dopaminergic cell death underlying PD. Of interest, treatment with IL- 1β and TNF-α induced minimal cell death when compared with other PD-related neurotoxicants. Although IL-1β induced a transient increase in reactive oxygen species (ROS) production within an hour, TNF-α did not increase ROS production even within 12 hours in dopaminergic neurons. The transcription factor, NF-κB was translocated into nucleus in response to IL-1β prior to ROS increase in dopaminergic cells. In addition, IL-1β activated the JNK 1/2 moderately in dopaminergic neurons and triggered the dopaminergic cell death.
