WikiBiomeThe human microbiome encyclopediaRanked matches across titles, topics, categories, and article introductions.
This page serves as a cross-reference point for the existing ahr concept page, which provides comprehensive coverage of AhR signaling, microbiome-derived ligands, and immune regulation. The aryl hydrocarbon receptor is a ligand-activated transcription factor that integr…
A Gram-positive, aerobic to facultatively anaerobic, spore-forming genus that bridges environmental and human microbiology. The genus encompasses both beneficial species (B. subtilis, B. coagulans as probiotics) and pathogens (B. cereus causing food poisoning, B. anthra…
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…

Clostridium perfringens is a Gram-positive, strictly anaerobic, spore-forming bacterium infamous for causing gas gangrene, food poisoning, and necrotizing enterocolitis (NEC) in premature infants. It is one of the most widely distributed pathogenic bacteria in nature, f…

Affects approximately 48 million women worldwide (WHO global infertility prevalence estimates). From a microbiome-metallomics perspective, female infertility sits at the intersection of the estrobolome (microbial estrogen metabolism), heavy metal reproductive toxicity (…

Bidirectional communication between the gut microbiota and the central nervous system, mediated by neural (vagus nerve, enteric nervous system), immune (cytokines, microglia), endocrine (HPA axis), and metabolic (SCFAs, neurotransmitter precursors, tryptophan metabolite…
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…

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…
Specialized proteins that escort metal ions from their point of entry to specific metalloenzyme targets, ensuring correct metalation in a cytoplasm crowded with competing metal-binding sites. Metallochaperones solve a fundamental problem in metal biology: how does the r…
Nuclear factor kappa-light-chain-enhancer of activated B cells (NF-kB) is a family of transcription factors that regulate inflammation, immune responses, cell survival, and proliferation. NF-kB is a convergence point where metal toxicity, pathogen signaling, and chronic…
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 …

Premenstrual syndrome (PMS) affects an estimated 20-40% of women of reproductive age, characterized by cyclical physical and psychological symptoms in the luteal phase (post-ovulation, pre-menstruation). While PMS has traditionally been attributed solely to hormonal flu…

Small, high-affinity iron-chelating molecules secreted by bacteria and fungi to scavenge ferric iron (Fe3+) from the environment. Siderophore competition is a fundamental ecological force in the gut microbiome: organisms with superior iron acquisition systems gain a dec…
A genus of Gram-positive, facultative anaerobic cocci that includes some of the most clinically significant human pathogens. Staphylococci are defined by their exceptionally comprehensive metal acquisition arsenal -- arguably the most thoroughly characterized of any bac…
The primary androgen in human biology, testosterone sits at a critical intersection in WikiBiome's framework: it is both regulated by the gut microbiome and disrupted by heavy metals, making it a node where environmental metal exposure, microbial ecology, and endocrine …
Tryptophan (Trp) is an essential amino acid metabolized via three competing pathways: the kynurenine pathway, the serotonin pathway, and the microbial indole pathway. The balance among these pathways is profoundly influenced by the gut microbiome, inflammation, and meta…
This page serves as a redirect and cross-reference point for the comprehensive virome concept page, which covers the gut virome, bacteriophage-bacteria interactions, phage therapy, and virome-disease associations in detail. The term viral microbiota emphasizes that viru…
