متن کاملIron and infection.
Iron has a central role in redox reactions and oxygen transport, and living organisms have developed efficient mechanisms for its acquisition, transport, and storage. In man, transferrin and lactoferrin are responsible for the transport of iron in the plasma and secretions, and nonfunctional iron is stored in ferritin. In order to compete with these powerful iron-conserving systems, microorgani...

A decrease in circulating Fe, or hypoferraemia, is one of the most constant features of infectious disease. Since Fe deprivation in bacterial cultures is regularly associated with inhibition of growth, it has been suggested that Fe deficiency may represent an important defence mechanism (Weinberg, 1990). The term ‘nutritional immunity’ has been introduced by Kochan (1973) to underline the impor...
