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…

Gut-Brain Axis
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…

Mitochondrial Dysfunction
Mitochondrial dysfunction refers to the impairment of mitochondrial energy production, redox balance, and signaling functions. Mitochondria are the primary targets of heavy metal toxicity in human cells, and they are also the organelles most dependent on metal cofactors…

Neurodegeneration and Metals
An umbrella concept encompassing the metallomic dimensions of Alzheimer's disease, Parkinson's disease, and other neurodegenerative conditions. The brain is uniquely vulnerable to metal toxicity: it has high metabolic demand, limited regenerative capacity, region-specif…

Oxidative Stress
Oxidative stress is the imbalance between the production of reactive oxygen and nitrogen species (ROS/RNS) and the capacity of biological antioxidant defense systems to detoxify them. It is the single most commonly invoked mechanism across metal toxicology in this wiki,…
