17286743 Ishido M: Melatonin inhibits maneb-induced aggregation of alpha-synuclein in rat pheochromocytoma cells. J Pineal Res. 2007 Mar;42(2):125-30.

Thus, melatonin prevents maneb-induced neurodegeneration at a nighttime physiological blood concentration, most likely by inhibiting the aggregation of alpha-synuclein as well as preventing mitochondrial dysfunction in PC 12 cells.

In this study, A53T mutant human alpha-synuclein transgenic mice (M83), which develop alpha-synuclein neuropathology, were treated with the pesticides paraquat and maneb (either singly or together), and their effects were analyzed.

Potential causative factors include environmental toxins and gene mutations that can combine to dysregulate the processing and degradation of alpha-synuclein.
Oxidative stress induced by the neurotoxins MPTP, paraquat, maneb, and rotenone causes lipid peroxidation and protein misfolding that affects cell death through members of the Bcl-2 family.

Maneb, a widely used fungicide, has been associated with Parkinsonism in humans.
Proteasomal dysfunction was accompanied by formation of cytoplasmic inclusions that were positive for alpha-synuclein immunostaining and significantly increased sodium dodecyl sulfate-insoluble alpha-synuclein aggregation seen by Western blot analysis.
