Sickle cell disease is a destructive genetic disorder characterized by the
formation of fibrils of deoxygenated hemoglobin, leading to the red blood cell
(RBC) morphology changes that underlie the clinical manifestations of this
disease. Using cryogenic soft X-ray tomography (SXT), we characterized the
morphology of sickled RBCs in terms of volume and the number of protrusions per
cell. We were able to identify statistically a relationship between the number of
protrusions and the volume of the cell, which is known to correlate to the
severity of sickling. This structural polymorphism allows for the classification
of the stages of the sickling process. Recent studies have shown that elevated
sphingosine kinase 1 (Sphk1)-mediated sphingosine 1-phosphate production
contributes to sickling. Here, we further demonstrate that compound 5C, an
inhibitor of Sphk1, has anti-sickling properties. Additionally, the variation in
cellular morphology upon treatment suggests that this drug acts to delay the
sickling process. SXT is an effective tool that can be used to identify the
morphology of the sickling process and assess the effectiveness of potential
therapeutics.
