Autophagy (from Greek, "self-eating") is the cellular process of degrading and recycling damaged organelles, misfolded proteins, and intracellular pathogens through lysosomal digestion. It is the cell's primary quality control mechanism -- a housekeeping system that bec…
Heavy metals exert some of their most devastating effects on the nervous system. lead, mercury, and arsenic are the three metals with the most extensively documented neurotoxic mechanisms, but cadmium, manganese, aluminum, and nickel also contribute to neurological dama…
The 6-24 month developmental window — when infants transition from breast milk to solid foods — represents a convergence of maximum vulnerability and maximum exposure. Immature detoxification systems, rapid organ development, and high food-to-body-weight ratios mean tha…
The developing infant represents a uniquely vulnerable window for heavy metal toxicity. Three factors converge to make the first years of life a critical period: an immature and rapidly assembling gut microbiome, a developing blood-brain barrier, and proportionally high…
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…
Parenteral nutrition (PN) -- the delivery of nutrients directly into the bloodstream via intravenous infusion -- is a life-saving intervention for patients who cannot absorb nutrition enterally. However, PN presents unique challenges for the metal-microbiome axis: it in…
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…
