Anxiety disorders are the most prevalent mental health conditions globally, affecting ~280 million people (~4.8% of the world population). They encompass generalized anxiety disorder (GAD), social anxiety, panic disorder, and phobias. In the WikiBiome context, anxiety f…
Alphabetical definitions of specialist terms used throughout this wiki. Where a full concept page exists, the term links to it. --- AhR (aryl hydrocarbon receptor) -- A ligand-activated transcription factor that senses microbial metabolites (especially indoles from tryp…
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…
Interleukin-22 (IL-22) is an immune signaling protein that helps coordinate host responses at epithelial surfaces. In the gut evidence represented by WikiBiome, group 3 innate lymphoid cells (ILC3s) are a prominent source, while Th17-associated responses can also includ…
Maternal immune activation (MIA) describes the phenomenon in which infection or inflammatory stimulation during pregnancy produces persistent neurological and microbiome alterations in offspring, increasing risk for autism spectrum disorder, schizophrenia, and other neu…
Inflammation is a broad concept, but in the metallomics context it has a specific character: heavy metals and pathogens activate overlapping inflammatory pathways, creating convergent pathology where distinguishing the metal contribution from the microbial contribution …
Multiple sclerosis (MS) is a chronic autoimmune demyelinating disease of the central nervous system, with a global prevalence of approximately 2.8 million attfield 2022 immunology ms nature review. The conventional framing centers on genetic susceptibility (HLA-DRB115:0…
Neuroinflammation is an immune response within the central nervous system (CNS)—the brain and spinal cord. It involves changing states of microglia, astrocytes, cells of the neurovascular unit, and, in some settings, immune cells recruited from the circulation. The resp…
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…
The NLRP3 inflammasome is a host innate-immune signaling complex that connects cellular danger signals to caspase-1 activation. In the canonical pathway represented in WikiBiome's evidence vault, caspase-1 processes the inflammatory cytokines IL-1beta and IL-18 and clea…
