Iron metabolism in the erythrophagocytosing Kupffer cell
Hitoshi Kondo, Kainosuke Saito, Joseph P. Grasso, Philip Aisen – 1 January 1988 – Like the peritoneal macrophage, the isolated Kupffer cell is capable of processing and releasing iron acquired by phagocytosis of immunosensitized homologous red blood cells. When erythrophagocytosis is restrained to levels which do not affect cell viability, or less than 1.5 red cells/macrophage (phagocytic index of 150%), over 40% of iron acquired from red cells is released within 24 hr. More active erythrophagocytosis results in greater release of iron but progressive deterioration in cell viability.
