People with this disease have atypical hemoglobin molecules called hemoglobin S, which can distort red blood cells into a sickle , or crescent, shape.
The loss of red blood cell elasticity is central to the pathophysiology of sickle cell disease. Normal red blood cells are quite elastic and have a biconcave disc shape, which allows the cells to deform to pass through capillaries. In sickle cell disease, low oxygen tension promotes red blood cell sickling and repeated episodes of sickling damage the cell membrane and decrease the cell's elasticity. These cells fail to return to normal shape when normal oxygen tension is restored. As … WebJun 11, 2024 · Sickle cell anemia, or sickle cell disease (SCD), is a genetic disease of the red blood cells (RBCs).
