[Does the cholesterol content in blood cells depend on its level in plasma?]

The cholesterol content in human erythrocytes, granulocytes and the total leucocyte fraction with varying levels of plasma cholesterol has been studied. There was no correlation between the cell cholesterol content and the levels of total, LDL and HDL cholesterol in the plasma. The mean cholesterol content in one cell has been found to be equal to 1.26 x 10(-13) g in the erythrocytes, 2.08 x 10(-12) g in the granulocytes and 3.35 x 10(-12) g in the total leucocyte fraction.
