Dyshomeostasis
The pathological disruption of normal metal homeostasis — the tightly regulated balance of essential trace elements (iron, zinc, copper, manganese, selenium, cobalt) and the effective exclusion of toxic metals (cadmium, lead, mercury, arsenic). Dyshomeostasis is a conve…

Ferroportin
The only known cellular iron exporter in mammals. Encoded by the SLC40A1 gene, ferroportin (FPN) sits on the basolateral membrane of enterocytes, the surface of macrophages, and the membrane of hepatocytes, controlling the flow of iron from these cells into the bloodstr…

Hepcidin
The master regulator of systemic iron homeostasis. Hepcidin is a 25-amino-acid peptide hormone produced primarily by hepatocytes that controls iron absorption, recycling, and distribution by binding to and degrading ferroportin (SLC40A1/FPN) -- the only known cellular i…

Lactoferrin
An iron-binding glycoprotein of the transferrin family that sequesters iron (and potentially other metals) from pathogens at mucosal surfaces and sites of inflammation. Lactoferrin is a key effector of nutritional immunity, complementing calprotectin's role in metal res…

Metal-Driven Inflammation
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 …

Siderophore Competition
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…
