Compared with control rats, in insulin-deficient rats less of the phospholipid label was distributed to the lighter HDL fraction and more to the heavier HDL fraction, and this difference was not due to changes in activity of lecithin: cholesterol acyltransferase or in the apparent activity of phospholipid transfer protein.

Baseline HDL cholesterol and phospholipids, pre beta-HDL in incubated plasma, plasma apolipoprotein (apo) AI, PLTP activity and cholesterol efflux to plasma were not different between the groups.

In both groups, HDL lipids, as well as plasma apo AI and PLTP activity decreased after 24 h of insulin (P<0.05 to P<0.01) compared to baseline and recovery, i.e. 1 week after insulin.

The univariate relationship between CETP and LDL-III was no longer significant after adjusting for PLTP activity.

PLTP-deficient mice have demonstrated increased antioxidation potential as well as a decrease in apolipoprotein B secretion and atherosclerotic lesions.

Plasma PLTP activity (2364+/-651 nmol/ml/h versus 1880+/-586 nmol/ml/h in control, mean +/- S.D., P <0.01) and CRP (1.64(0.89-3.23)mg/l versus 0.99(0.53-2.23 mg/l, median (interquartile range), P<0.01) were increased in diabetic subjects.

PLTP activity correlated significantly with age, BMI, HbA1c, log(CRP) and apolipoprotein AI and B in diabetic subjects.

Plasma very low density lipid protein (VLDL)+LDL cholesterol, LDL cholesterol, HDL phospholipids, apolipoprotein (apo) A-I, apo B, CETP activity, PLTP activity, cholesterol esterification, cholesteryl ester transfer and the capacity of plasma to induce cholesterol efflux from Fu5AH cells and fibroblasts were higher in diabetic patients.

We assessed cerebrospinal fluid (CSF) levels of apolipoprotein E (apoE), phospholipid transfer protein (PLTP) activity, cholesterol, secreted amyloid-beta protein precursor alpha and beta (sAbetaPPalpha, sAbetaPPbeta), amyloid-beta peptides 1-40 (Abeta_{40}) and 1-42 (Abeta_{42}), total tau and tau phosphorylated at threonine 181 (pTau) in neurologically healthy, cognitively intact adults.

|
Using partial correlations of CSF biomarkers with apoE, PLTP activity, age and gender, apoE remained significantly correlated with sAbetaPPalpha, sAbetaPPbeta, Abeta_{40}, total and pTau (p < 0.001).

The presence of apoE epsilon2 was associated with lower levels of apoE, PLTP activity and Abeta_{42}, while APOEepsilon4} had no significant impact on any of the measured variables.

In this study we provide evidence that phospholipid transfer protein (PLTP), one of the main lipid transfer proteins in the brain, significantly reduces levels of phosphorylated tau and increases levels of the inactive form of glycogen synthase kinase-3beta (GSK3 beta) in HCN2 cells.

Furthermore, inhibition of phosphatidylinositol-3 kinase (PI3K) reversed the PLTP-induced increase in levels of GSK3 beta phosphorylated at serine 9 (pGSK3 beta(Ser9)) and partially reversed the PLTP-induced reduction in tau phosphorylation.

|
We provide evidence that the PLTP-induced changes are not due to activation of Disabled-1 (Dab1), insofar as PLTP reduced levels of total and phosphorylated Dab1 in HCN2 cells.

We have also shown that inhibition of tyrosine kinase activity of insulin receptor (IR) and/or insulin-like growth factor 1 (IGF1) receptor (IGFR) reverses the PLTP-induced increase in levels of phosphorylated Akt (pAkt(Thr308) and pAkt(Ser473)), suggesting that PLTP-mediated activation of the PI3K/Akt pathway is dependent on IR/IGFR receptor tyrosine kinase activity.
