Web23 Mar 2024 · Although iron metabolism is strictly controlled in the body, disturbance of iron homeostasis under certain type of condition leads to innate and adaptive immune response. In innate immunity, iron regulates macrophage polarizations, neutrophils recruitment, and NK cells activity. Web4 Apr 2024 · Iron metabolism is regulated at the systemic and cellular levels. Systemic iron homeostasis is mostly adjusted by the hepcidin-/ferroportin axis [28,29]. Because iron losses are relatively small, iron absorption and its regulation by hepcidin and ferroportin (FPN) determine systemic iron levels [30]. pavco ventas https://gitamulia.com
