"Upon peripheral injection, aluminum activates the nuclear factor-kappa beta (NF-κB) pathway in the brain, resulting in the release of proinflammatory molecules. The increased immunoinflammatory signal downregulates the activity of acetylcholinesterase to activate acetylcholine-mediated immunosuppression. If immunosuppression is not achieved, the excessive immunoinflammatory response may impair neurodevelopmental processes producing autistic pathology."

Isn't science neat?
