Human erythrocytes survive in the circulation for about 120 days. How do they appreciate aging and determine their lifespan? The objective of this monograph is to present a fully new compendium (molecular-sensing) of Heinz body formation mechanisms inherent in human erythrocytes, whereby 1- 1 (and 2- 2) interface of the hemoglobin molecule ( 2 2) controls removal of erythrocytes from the blood circulation by triggering degradation of the molecule to hemichrome, and subsequent clustering of Heinz bodies within the erythrocytes depending on the internal and extraneous conditions of the...
