Hepcidin and ferroptosis
WebIn cases of ferroportin dysfunction, iron accumulates in the cell and causes ferroptosis. Hepcidin suppresses ferroportin levels and inflammatory activation increases hepcidin production. Mild inflammation in schizophrenia and bipolar disorder may alter hepcidin and ferroportin. Web11 apr. 2024 · Ferroptosis is a type of programmed cell death that is iron-dependent and different from apoptosis, cell necrosis, and autophagy. C. irritans infects fish and causes ferroptosis of host cells, and cell death information is recognized by APCs. Additionally, target cells secrete hepcidin, which participates in nonspecific immunity.
