Burkholderia pseudomallei modulates host iron homeostasis to facilitate iron availability and intracellular survival.

Background: The control over iron homeostasis is critical in host-pathogen-interaction. Iron plays not only multiple roles for bacterial growth and pathogenicity, but also for modulation of innate immune responses. Hepcidin is a key regulator of host iron metabolism triggering degradation of the iron exporter ferroportin.
