Red blood cells (RBC) carry the majority of sphingosine-1-phosphate (S1P). Here, the authors show that RBC dynamically regulate S1P levels in response to metabolic stress and employ them to regulate glucose uptake, glycolysis and the pentose phosphate pathway as protection against lipid peroxidation.
