Iron Metabolism

The Iron Metabolism Laboratory studies a wide spectrum of iron-related issues from basic mechanisms of iron homeostasis to disorders of iron metabolism. We are interested in iron nutrition and iron deficiency, diseases of iron loading (haemochromatosis, thalassaemia), perinatal iron metabolism, and the use of nanotechnology to modulate body iron levels. The laboratory integrates genetic and molecular studies with biochemical and physiological approaches. We have a particular interest in understanding how the liver-derived hormone hepcidin regulates body iron homeostasis. The ultimate goal of our work is to improve the diagnosis and treatment of a range of conditions where iron metabolism is perturbed.

CURRENT RESEARCH

  • basic mechanisms of intestinal iron absorption and its regulation. Increased absorption characterises most iron loading disorders such as haemochromatosis and thalassaemia
  • exploring novel mechanisms of regulating iron intake in pregnancy and early postnatal life which has significant implications for maternal health as well as infant nutrition and complementary feeding
  • using novel nanoparticle technology to develop better methods for delivering iron removing agents for the liver, brain and heart, as well as tumours
  • studying the natural history of the iron loading disorder hereditary haemochromatosis and exploring markers for monitoring the effectiveness of treatment
  • examining the mechanisms underlying hepatic encephalopathy, the neurophsychiatric syndrome that often accompanies severe liver disease
  • determining whether iron supplementation can reduce tic severity in people with Tourette’s syndrome
