Figure 1 From: Sequestration of free cholesterol in cell membranes by prions correlates with cytoplasmic phospholipase A2activation Correlation between the amounts of PrP Sc and free cholesterol in ScGT1 cells. The amounts of PrPSc in GT1 cells (○) or ScGT1 cells (●) treated with varying amounts of GDNF for 7 days were plotted against the amounts of free cholesterol in the same cells (expressed as ng cholesterol/mg protein).Back to article page
