In sickle cell disease, hemoglobin—the oxygen-carrying component of blood—forms fibers that stiffen red blood cells and cause life-threatening symptoms. Using light-scattering techniques to study the detailed thermodynamics of this process, researchers reporting in the November 5 issue of the Biophysical Journal, a Cell Press publication, have determined the strength of the forces that hold these fibers intact. The information could be used to design therapies that interfere with the sickling process.
