Iron trafficking and metabolism in macrophages: contribution to the polarized phenotype.

Abstract excerpt

During inflammation, proinflammatory macrophages sequester iron as a well known bacteriostatic mechanism. Alternative activation of macrophages is linked to tissue repair, and during this process the expression pattern of genes important for iron homeostasis is distinct from that in proinflammatory macrophages. This leads to an increased capacity of the alternatively activated macrophages for heme uptake, via...
