There is evidence available suggesting that membrane alterations occur in Alzheimer's disease including the metabolism of membrane phospholipids.

Abstract
There is evidence available suggesting that membrane alterations occur in Alzheimer's disease including the metabolism of membrane phospholipids. We have quantitated in vitro the phospholipase D activity of homogenates from Alzheimer's disease brain tissue. There was a significant increase of this enzyme activity as compared to controls. Amyloid beta protein is the predominant protein of the characteristic senile plaques found in Alzheimer's disease. Treatment of LA-N-2 cells, a human cholinergic neuroblastoma clone, with amyloid beta protein results in an activation of phospholipases A, C and D.File in questo prodotto:
