Does higher red blood cell (RBC) lactate transporter activity explain impaired RBC deformability in sickle cell trait?

Jpn J Physiol. 2005 Dec;55(6):385-7. doi: 10.2170/jjphysiol.S653. Epub 2006 Jan 31.

Abstract

Lactate and H(+) are suggested to promote the sickling process in red blood cells (RBCs) containing hemoglobin S. We demonstrated greater activity of the RBC monocarboxylate cotransporter MCT-1, lower RBC deformability and impaired hematological indices in sickle cell trait (SCT) carriers compared to control subjects, suggesting an involvement of MCT-1 in hemorheological disturbances in SCT carriers.
