Effects of hemin on cells

Effects of Hemin on Cells

Upon destruction of erythrocytes, a process also called hemolysis, haemoglobin and, subsequently, free protoporphyrin IX (also called free heme or hemin) is released. Free heme is well known for its cytotoxic and pro-inflammatory properties. For instance, upon incubation of neutrophils with heme a stronger production of reactive oxygen species (ROS) by the cells was observed. In experiments with erythrocytes we could show that free heme induces further haemolytic events, leading to a vicious circle between heme release and further hemolysis.

Upon pre-incubation of hemin with chlorite (ClO2-) we were able to efficiently inhibit the haemolytic effect of free heme
