Endogenous trace element homeostasis

Endogenous trace element homeostasis refers to the complex physiological mechanisms that maintain optimal concentrations of essential minerals, such as iron, zinc, copper, and selenium, within the body (NIH, 2023). This regulation is achieved through a coordinated network of specialized transporters (e.g., ZIP and ZnT families), storage proteins like ferritin and metallothionein, and systemic signaling molecules like hepcidin (Nature Reviews Molecular Cell Biology, 2017). Disruptions in these homeostatic mechanisms can lead to either deficiency or toxicity, contributing to various pathological conditions including anemia, Wilson's disease, and neurodegenerative disorders (StatPearls, 2023). While not a single molecular target, the individual components of these pathways—such as ferroportin for iron or CTR1 for copper—serve as critical points for therapeutic intervention (PubMed, 2022). Drugs interacting with these systems typically include chelating agents to remove excess elements or mineral supplements to address deficiencies (PubChem, 2024). Because it encompasses a broad range of distinct molecular pathways rather than a single protein or receptor, it is classified as a physiological process rather than a discrete therapeutic target.

Therapeutic strategies involve the use of chelating agents to sequester and remove excess metal ions, or the administration of elemental supplements to restore physiological levels in cases of deficiency (PubChem, 2024).
