Role of Haptoglobin in Protecting the Toxic Effects of Hemoglobin in Various Pathologies

Abstract

The review presents modern domestic and foreign literature data on the blood plasma protein haptoglobin, its structure, synthesis, function and interaction with hemoglobin. The ability of haptoglobin in interaction with hemoglobin to reduce the toxic effect of the latter is shown. Clinical studies of such interaction in various pathological conditions such as diabetes mellitus, sickle cell anemia, malaria, sepsis, etc. are described. It is noted that the development of new haptoglobin derivatives can contribute to the prevention of hemoglobin toxicity in hemolytic diseases.
