Journal of Trace Elements in Medicine and Biology: Aluminium in brain tissue in autism "Extraordinarily High"
NOTE: You might recall that a "freezer malfunction" at Harvard University destroyed one third of the world's largest autistic brain collection. Can you imagine the information lost?
J.B. Handley has written about this paper at his Medium site - STAFFORDSHIRE, England — Professor Chris Exley is a formidable scientist, which is perhaps more important than you think, because a study he published today with his colleagues in the Journal of Trace Elements in Medicine and Biology may just be the “smoking gun” to prove that vaccines are triggering autism that we’ve all been waiting for. Professor Exley is a Professor of Bioinorganic Chemistry at Keele University in Staffordshire, England. He received a Ph.D. in a subject that makes him highly qualified to author this latest paper: “the ecotoxicology of aluminium.”
Autism spectrum disorder is a neurodevelopmental disorder of unknown aetiology. It is suggested to involve both genetic susceptibility and environmental factors including in the latter environmental toxins. Human exposure to the environmental toxin aluminium has been linked, if tentatively, to autism spectrum disorder. Herein we have used transversely heated graphite furnace atomic absorption spectrometry to measure, for the first time, the aluminium content of brain tissue from donors with a diagnosis of autism. We have also used an aluminium-selective fluor to identify aluminium in brain tissue using fluorescence microscopy. The aluminium content of brain tissue in autism was consistently high. The mean (standard deviation) aluminium content across all 5 individuals for each lobe were 3.82(5.42), 2.30(2.00), 2.79(4.05) and 3.82(5.17) μg/g dry wt. for the occipital, frontal, temporal and parietal lobes respectively. These are some of the highest values for aluminium in human brain tissue yet recorded and one has to question why, for example, the aluminium content of the occipital lobe of a 15 year old boy would be 8.74 (11.59) μg/g dry wt.? Aluminium-selective fluorescence microscopy was used to identify aluminium in brain tissue in 10 donors. While aluminium was imaged associated with neurones it appeared to be present intracellularly in microglia-like cells and other inflammatory non-neuronal cells in the meninges, vasculature, grey and white matter. The pre-eminence of intracellular aluminium associated with non-neuronal cells was a standout observation in autism brain tissue and may offer clues as to both the origin of the brain aluminium as well as a putative role in autism spectrum disorder.

We have made the first measurements of aluminium in brain tissue in ASD and we have shown that the brain aluminium content is extraordinarily high. We have identified aluminium in brain tissue as both extracellular and intracellular with the latter involving both neurones and non-neuronal cells. The presence of aluminium in inflammatory cells in the meninges, vasculature, grey and white matter is a standout observation and could implicate aluminium in the aetiology of ASD
