Protection of neurons from apoptosis by apolipoprotein E-containing lipoproteins does not require lipoprotein uptake and involves activation of phospholipase Cgamma1 and inhibition of calcineurin.

Abstract excerpt

Apolipoprotein E-containing lipoproteins (LpE) are generated in the central nervous system by glial cells, primarily astrocytes, and are recognized as key players in lipid metabolism and transport in the brain. We previously reported that LpE protect retinal ganglion neurons from apoptosis induced by withdrawal of trophic additives (Hayashi, H., Campenot, R. B., Vance, D. E., and Vance, J. E. (2007) J. Neurosci....
