A genus of Gram-positive, facultatively anaerobic, filamentous bacteria that are among the most abundant colonizers of the human oral cavity. Actinomyces species, particularly A. naeslundii, play dual roles as early dental plaque colonizers and as opportunistic pathogen…
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…
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…
Progressive inflammatory disease of the arterial wall characterized by lipid accumulation, immune cell infiltration, and fibrous plaque formation. In the metallomics framework, atherosclerosis sits at the convergence of three interacting systems: heavy metal toxicity, g…
Atherosclerosis is a chronic inflammatory disease of arterial walls characterized by lipid-laden plaque formation, endothelial dysfunction, and progressive vascular occlusion. It is the pathological substrate underlying coronary artery disease, stroke, and peripheral ar…
Cardiovascular disease (CVD) -- encompassing atherosclerosis, coronary artery disease, hypertension, myocardial infarction, heart failure, and stroke -- is the leading cause of death globally. The gut-heart axis has emerged as a central paradigm linking microbial metabo…
Coronary artery disease (CAD) -- the progressive narrowing of coronary arteries by atherosclerotic plaque -- is the single leading cause of death globally, responsible for approximately 9 million deaths annually. CAD encompasses stable angina, unstable angina, and myoca…
A Gram-negative obligate anaerobe traditionally considered an oral commensal, but increasingly recognized as an opportunistic pathobiont with the ability to translocate from oral biofilms to the gastrointestinal tract and bloodstream. Leptotrichia species are prominentl…
The oral microbiome is the second most complex microbial community in the human body after the gut, harboring ~700 species across distinct niches (tongue, buccal mucosa, gingival crevice, saliva, dental plaque). While traditionally studied in the context of dental disea…
Psoriasis is a chronic, immune-mediated inflammatory skin disease characterized by keratinocyte hyperproliferation, resulting in well-demarcated erythematous plaques with silvery scales. Affecting approximately 2-3% of the global population, psoriasis is now understood …
Rothia is a genus of Gram-positive, facultatively anaerobic bacteria in the family Micrococcaceae (phylum Actinobacteria). The most commonly identified species in microbiome studies are Rothia dentocariosa and Rothia mucilaginosa, both of which are primary inhabitants o…
This knowledge-base record is being expanded from WikiBiome’s evidence graph.
A genus of Gram-positive facultative anaerobes that occupy niches ranging from benign commensals (dental plaque, skin) to acute pathogens (pharyngitis, impetigo, invasive disease). Streptococci are uniquely manganese-dependent for catalytic scavenging of reactive oxygen…
The primary architect of dental caries -- the most prevalent chronic infectious disease worldwide. S. mutans is a Gram-positive, facultative anaerobe that colonizes tooth surfaces and produces the acid-rich, metal-managed biofilms known as dental plaque. What sets this …
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…
The most widespread nickel-dependent virulence factor across human pathogens. Urease is found in at least 40 prokaryotic and 9 eukaryotic pathogenic species, making it the single most important enzyme linking dietary/environmental nickel to infectious disease.
