When we looked in the autism brain tissues, we found nearly all of the aluminum was, first of all, inside cells, but not even inside neurocells but inside what are called the housekeeping cells of the brain—the glial cells, the microglia or, indeed, cells which are called inflammatory or pro-inflammatory cells. Now, these are cells which are responding, usually, to some sort of perturbation in the brain. They are cells which are trying to solve a problem that might have been caused a small inflammatory event would invite cells to come to that event to try and help out to solve the problem caused in that area of the brain tissue.
Some of those cells will originate from the brain itself, but some of them originate from the body. The brain calls for help and cells from the rest of the body come into the brain to help. Now, the startling and, for me, shocking observation that we made is that some of those cells, which are coming to help, are full of aluminum. Well, they cannot help and they will die and will release the aluminum into the brain tissue. And so they will be releasing acutely toxic amounts of aluminum into particular areas of the brain.
We have looked at what happens to the aluminum adjuvant when it’s injected, and we have shown that certain types of cells come to the injection site and take up the aluminum inside them. These same cells are the ones we also see in the brain tissue in autism. So, for the first time, we have a link that, honestly, I had never expected to find between aluminum as an adjuvant in vaccines and that same aluminum potentially could be carried by those same cells across the blood-brain barrier into the brain tissue where it could deposit the aluminum and produce a disease, an encephalopathy. It could produce a more severe and disabling form of autism.
