Your quite right. The oxidative stress hypothesis is also supported by
the observations that iron is significantly elevated in the substantia
nigra of PD brains (Dexter et al. 1989a,b,1991; Jenner et al. 1992).
Although, I'm not too familiar about ILs role, in my opinion cytokine
induction is a secondary phenomenon following the initial neuronal death.
I do believe that they (cytokines) contribute to (as much as they help
against) degenerative processes (which remains to be proven).
