Iron release by healthy volunteer (○) and HH patient (•) monocytes. After erythrophagocytosis, monocytes were incubated in RPMI from 0 to 48 hours. At a given time point, cells and supernatants were collected and 59Fe activity measured in both fractions. Results are expressed as percentage of the total iron in the system (mean ± standard deviation [SD] of six experiments).
