The selective and conjoint loss of red cell lipids

  • Text
  • PDF
Abstract

The pattern of lipid loss from the membrane of red cells incubated in serum is influenced by the availability of glucose. Under homeostatic conditions with respect to glucose, cholesterol alone is lost. This results from esterification of free cholesterol in serum by the serum enzyme, lecithin:cholesterol acyltransferase, and is associated with a proportional decrease in membrane surface area, reflected by an increased osmotic fragility. This selective loss of membrane cholesterol also occurs in hereditary spherocytosis (HS) red cells, even after incubation for 65 hr in the presence of glucose. The loss of free cholesterol from red cells relative to its loss from serum, under these conditions, is greatest at higher hematocrits, similar to those found in the spleen.
