Iron: effect of overload and deficiency

Area of Science:

• Biochemistry
• Human Physiology
• Medical Science

Background:

• Iron is an essential redox-active metal vital for biological processes like enzyme function and oxygen transport.
• Biological organisms tightly regulate iron levels due to its potential toxicity when in excess.
• Dysregulation of iron homeostasis is implicated in various diseases, including anemia and neurodegeneration.

Purpose of the Study:

• To provide an overview of human mechanisms for controlling body iron levels.
• To discuss the therapeutic applications of iron supplementation and chelation.
• To explore the role of iron dysregulation in disease and potential treatments.

Main Methods:

• Review of established clinical procedures for iron management.
• Discussion of iron chelating molecules and their therapeutic targets.
• Examination of research into iron chelators for infectious diseases and cancer.

Main Results:

• Iron supplementation is an established treatment for anemia.
• Iron chelation therapy is effective for systemic iron overload.
• Iron chelation shows promise for treating neurodegenerative diseases.

Conclusions:

• Human iron homeostasis is tightly regulated through various mechanisms.
• Iron supplementation and chelation are vital clinical tools for managing iron-related disorders.
• Iron chelation therapy holds future potential for treating neurodegenerative conditions and infectious diseases.
