Progress and Prospects in Parkinson's Research/Causes/Toxins/Dieldrin
Dieldrin is an insecticide which was invented in the 1940s. However once it is used it is persistent and seems to gain in toxicity as it passes up through the food chain. It has been linked to a number of diseases in humans and, as a result, it has been banned in many countries.
Uversky et al  showed that pesticides including Dieldrin were responsible for the formation of alpha-synuclein fibrils in dopaminergic neurons.
Kanthasamy et al  produced evidence linking Dieldrin to the onset of Parkinson’s Disease.
Richardson et al  established the toxicity of Dieldrin to dopaminergic neurons. Their conclusions state:-
"These data suggest that developmental exposure to dieldrin leads to persistent alterations of the developing dopaminergic system and that these alterations induce a "silent" state of dopamine dysfunction, thereby rendering dopamine neurons more vulnerable later in life."
Hatcher et al  demonstrated that dopaminergic neurons (in mice) were severely damaged by Dieldrin.
