Iron is an essential oligoelement that incorporates into proteins as a biocatalyst or electron carrier. The intracellular pathogen Salmonella enterica serovar Typhimurium ( Typhimurium) takes iron as free reduced ferrous cation or as oxidized ferric cation complexed to siderophores or ferrichromes. Deficiencies in ferrous or ferric iron uptake attenuate Typhimurium virulence, but how the uptake systems are used in the intracellular environment remains poorly understood.

Laminin-5 (Ln-5) plays an important role for tumour migration and shows an increased expression in areas of direct tumour/stroma interactions.
