Not just the flu but flaviviruses and heptachlor could trigger Parkinson's through cross-targeting

Cross-targeting hypothesis suggests that simultaneous infections on one target triggers autoimmunity.  One infection on the outside of the target cell and one infection, like a virus, on the inside of the target.  

Target: substantia nigra neurons
Inside: swine flu, flavivirus, heptachlor
Outside: mycobacteras

Is this a shared virus between melanoma and parkinson's? Flaviviruses?

hepatitis C which is a flavivirus has also been linked to risk of parkinson's

swine flu and parkinson's

Note that it only takes one virus to mark the inside.

Can heptachlor replace the virus in some cases? thus explaining the milk and parkinson's disease connection since milk has been found to be contaminated with heptachlor.  The inside of the cell has been marked as foreign and non self...a chemical instead of a virus.

Breast cancer and melamona cancers are increased in parkinson's patients

Does too much heptachlor leaves deposits in the breast and brain?

Heptachlor also deposits in the breast where it acts like a carcinogen with the  viruses: hpv or epstein barr

psoriasis and parkinon's connection

mycobacteria connections

ischemic stroke connected to high cholesterol and parkinson's

(evidence that mycobacterias are there)

Up until now I have said that cancer is caused by a carcinogen which inhibits a polymerase and a virus.  Obviously heptachlor and viruses can exist together in the substantia nigra neurons.  The reason these neurons die and do not become cancerous is because neurons cannot go through cell division because they lack centrioles.
