APOE and dementia: In addition to cholesterol, PLs and TGs, cholesterol esters (CE) can also be found in ApoE [104], but studies comparing the lipid profile of ApoE3 vs. ApoE4 showed that the PLs glycerophosphatidylcholine (PC), glycerophosphatidylinositol (PI), glycerophosphatidylserine (PS), and glycerophosphatidylethanolamine (PE) were significantly reduced in the dementia-associated apolipoprotein [105].
