Abstract: 
Protein-lipid interactions in the nervous system may provide insight into the causes of neurological disorders. In this study, we elucidated if expression of human presenilin 1 (PS1) in a mouse model changes the physico-chemical properties of brain membranes. PS1 is a multifunctional transmembrane protein and part of the gamma-secretase complex. This complex is critical for the production of the Alzheimer related amyloid beta peptide. Brain membranes isolated from mice expressing a human wild-type PS1 transgene are less fluid and contain higher cholesterol and sphingomyelin levels. Moreover, our data reveal significant changes in membrane micro-domains and indicate that PS1 induces the formation of lipid rafts. (C) 2009 Elsevier Inc. All rights reserved.
