Amyloid-beta (Aβ) is a 36–43 amino acid peptide derived from the proteolytic cleavage of amyloid precursor protein (APP) by beta-secretase (BACE1) and gamma-secretase. Its aggregation from soluble monomers into insoluble fibrillar plaques in the brain is the defining ne…
The process by which soluble amyloid-beta (Aβ) monomers assemble into neurotoxic oligomers and insoluble fibrillar plaques in the brain -- the defining neuropathological event of alzheimers disease. What distinguishes WikiBiome's treatment of this process from conventio…

The most common form of dementia, affecting an estimated 55 million people worldwide and projected to triple by 2050 zhang 2024 recent advances alzheimers mechanisms trials. Characterized by progressive memory loss, cognitive decline, amyloid-beta plaques, and neurofibr…
An essential trace element with a striking dual nature: required for survival as a cofactor for critical enzymes (SOD1, cytochrome c oxidase, ceruloplasmin), yet toxic in excess through Fenton-like redox cycling and mis metallation of iron-sulfur clusters. Copper is ele…

Escherichia is a genus of Gram-negative, facultatively anaerobic bacteria in the Enterobacteriaceae family. The primary species E. coli is simultaneously the most studied bacterium in biology and one of the most consistently enriched organisms in disease-associated micr…

A transition metal occupying a central position in this wiki's evidence base. Nickel is toxic and carcinogenic to humans, yet an essential cofactor for pathogen virulence enzymes. It is the most frequent contact allergen worldwide and drives a wide spectrum of systemic …
Tau is a microtubule-associated protein essential for maintaining the structural integrity of neuronal axons. In health, tau binds to and stabilizes microtubules, enabling axonal transport of organelles, vesicles, and signaling molecules. When tau becomes hyperphosphory…
Copper is elevated in the blood/serum of nearly every disease state examined in this wiki: | Disease | Cu Direction | Evidence | |---|---|---| | PCOS | Elevated | SMD = 0.51, p < 0.0001 (meta-analysis of 9 studies) | | Breast cancer | Elevated | SMD 2.44 in plasma/serum…
Fish is the primary dietary source of methylmercury (MeHg) -- a potent neurotoxin that crosses the blood-brain barrier, depletes glutathione, and can increase amyloid-beta production and tau phosphorylation mercury. MeHg is 95-100% absorbed in the intestinal tract. An e…
