Antimicrobial Resistance
The ability of microorganisms to survive and replicate in the presence of antimicrobial agents — antibiotics, antifungals, antivirals, antiparasitic drugs — at concentrations that would normally inhibit or kill them. Antimicrobial resistance (AMR) is designated by the W…

Bacteriophages
Viruses that exclusively infect bacteria. Bacteriophages -- phages for short -- are the most abundant biological entities on Earth, outnumbering bacteria in most environments by ratios of 1:1 to 10:1. In the human gut, the phageome represents a powerful but underexplore…

Co-Selection
The process by which selection pressure from one agent — typically a heavy metal — simultaneously selects for resistance to a structurally unrelated agent such as an antibiotic, because the resistance determinants are genetically linked on the same mobile genetic elemen…

Cuproptosis
A distinct form of regulated cell death caused by excess intracellular copper binding to lipoylated proteins in the TCA cycle, first characterized by Tsvetkov et al. in Science (2022). Unlike ferroptosis (iron-dependent lipid peroxidation) or apoptosis (caspase-dependen…

Glyoxalase I
The third nickel-dependent enzyme class in human pathogens, after urease and hydrogenase. Glyoxalase I detoxifies methylglyoxal, a reactive and toxic byproduct of glycolysis. While less well-known than urease or hydrogenase as a virulence factor, GloI is emerging as a s…

Gut Microbiome
The community of trillions of microorganisms — bacteria, archaea, fungi (mycobiome), viruses, and bacteriophages — inhabiting the human gastrointestinal tract, with the highest density in the colon (~10¹¹ cells/g). The gut microbiome encodes 100–150 times more genes tha…

Human Milk Oligosaccharides (HMOs)
Human milk oligosaccharides are a diverse family of over 200 structurally distinct complex sugars found in breast milk. They are the third most abundant solid component of human milk (after lactose and lipids), yet they are not digestible by the infant. Their sole purpo…

Immune Balance
The immune system is not a monolith but a dynamic equilibrium between pro-inflammatory effector responses (Th1, Th2, Th17) and anti-inflammatory regulatory responses (Treg, IL-10, TGF-beta). Metals and the microbiome are two of the most potent environmental modulators o…

Interleukin-6 (IL-6)
Interleukin-6 is a pleiotropic cytokine that sits at the crossroads of innate immunity, adaptive immunity, and metabolism. It is one of the most frequently elevated inflammatory mediators across conditions in this wiki — appearing in disease signatures spanning IBD, aut…

Intestinal Permeability
The intestinal epithelium is a single-cell-thick barrier separating the lumen -- home to trillions of microbes and ingested metals -- from the systemic circulation. When this barrier fails, the consequences cascade: microbial products translocate, metals gain unrestrict…

Metal Chelation Therapy
Chelation therapy uses molecules with high affinity for specific metal ions to form stable, excretable complexes, removing toxic metals from the body. The word derives from Greek "chele" (claw) -- the chelator grips the metal ion at multiple coordination sites. While ch…

Metallothionein
A family of small (6-7 kDa), cysteine-rich proteins that bind heavy metals with extraordinary affinity. Metallothioneins (MTs) are the cell's primary chemical defense against metal toxicity -- they sequester cadmium, mercury, lead, and other toxic metals, preventing the…

Microglia
Microglia are the resident immune cells of the central nervous system, constituting 5-12% of all brain cells. They function as the brain's surveillance and defense system -- scanning for damage, clearing debris, pruning synapses during development, and mounting inflamma…

Nickel Transporters
Specialized membrane proteins that import nickel into bacterial cells, supplying the essential cofactor for virulence enzymes including urease, NiFe-hydrogenase, and Ni-glyoxalase. Because mammals produce no known nickel-requiring proteins, these transporters represent …
