Bacterial Receptors for Host Transferrin and Lactoferrin: Molecular Mechanisms and Role in Host–Microbe Interactions

Abstract excerpt

Iron homeostasis in the mammalian host limits the availability of iron to invading pathogens and is thought to restrict iron availability for microbes inhabiting mucosal surfaces. The presence of surface receptors for the host iron-binding glycoproteins transferrin (Tf) and lactoferrin (Lf) in globally important Gram-negative bacterial pathogens of humans and food production animals suggests that Tf and Lf are...
