Iron overload or haemochromatosis (also spelled hemochromatosis in American English) indicates increased total accumulation of iron in the body from any cause and resulting organ damage. The most important causes are hereditary haemochromatosis (HH or HHC), a genetic disorder, and transfusional iron overload, which can result from repeated blood transfusions. WebInsulin signaling and iron metabolism are interconnected, as high tissue iron stores are associated with insulin resistance, and conversely, impaired insulin signaling may lead to iron accumulation in an affected tissue. Excess iron accumulation in tissue triggers iron-dependent oxidative stress.
WebActive inflammatory processes and iron accumulation are hallmarks of a variety of neurodegenerative diseases that include Parkinson's disease (PD) and Alzheimer's disease (AD) (Hunot and Hirsch 2003; Ong and Farooqui 2005; Cahill et al. 2009; Sian-Hulsmann et al. 2011; von Bernhardi and Eugenin 2012 ).
