Iron Metabolism: from Molecular Mechanisms to Clinical Consequences

Data

Official data in SubjectManager for the following academic year: 2024-2025

Topic

During the course we will discuss the role of iron in the metabolism. We will deal with the iron demand of microorganisms and with the role of iron in the protective mechanisms against bacterial infections. We will discuss the possibilities of iron uptake and intracellular iron utilistaion, especially heme synthesis, and the syntesis of iron-sulfur clusters. The iron storage and iron mobilization from stores will be discussed in details. We reveal the functions of iron regulatory factors, their crosstalks, and the functions of the iron-containing proteins. Based on the brand new literature we discuss the the positive and negative regulators of the master iron regulator hepcidin. During the course we will deal with the different types of iron disorders and diseases (anemias, thalassemias, secondary iron overload, hemochromatosis) their genetic background, and therapeutic approaches. Based on the most actual findings the role of iron in the developpment of neurodegenerative diseases (Parkinson's disease, Alzheimer's disease and Huntington's disease) will be also discussed.
