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…
A genus of spirochete bacteria transmitted by Ixodes ticks, best known as the causative agent of Lyme disease -- the most common tick-borne illness in the Northern Hemisphere. Borrelia burgdorferi sensu lato comprises approximately 20 genospecies, with B. burgdorferi se…
The primary intracellular iron storage protein, capable of sequestering up to 4,500 iron atoms in a single molecule as a mineralized ferric oxyhydroxide core. Ferritin is one of the most elegant solutions evolution has produced for the iron paradox: iron is essential fo…
Kynurenine is the primary metabolite of the kynurenine pathway, which handles ~95% of tryptophan catabolism in the body. While serotonin gets more attention, the kynurenine pathway is quantitatively dominant -- and its downstream metabolites span the range from neuropro…
The labile metal pool (LMP) is the fraction of intracellular metal that is bioavailable -- loosely coordinated with small molecules, transiently protein-bound, or truly "free" in solution. This pool is vanishingly small (often <1 free atom per cell for zinc and copper) …
Reactive oxygen species — superoxide (O2•−), hydrogen peroxide (H2O2), and hydroxyl radical (OH•) — are chemically reactive molecules generated during normal metabolism and massively amplified by heavy metal exposure. ROS are both weapons (the host uses them to kill pat…
