    Bacterial Lipopolysaccharides Change Membrane Fluidity with Relevance to Phospholipid and Amyloid Beta Dynamics in Alzheimer's Disease
    Author(s): Ian James MartinsIan James Martins

    Bacterial lipopolysaccharides (LPS) and their increase in plasma in individuals in the developing world has become of major concern. LPS can transform cells by their rapid insertion into cell membranes that partition into cholesterol/sphingomyelin domains. LPS alter cell phospholipid dynamics associated with the recruitment of the Alzheimer’s disease amyloid beta (Aβ) peptide with the promotion of toxic Aβ oligomer formation. The common pattern of naturally occurring phospholipids such as1-palmitoyl-2-oleolyl-phosphatidylcholine in cells confers cells with the rapid transfer of Aβ and phospholipids. Phospholipids such as dipalmitoylphosphatidylcholine (DPPC), dimyristoylphosphatidylcholine (DMPC) and dioleoylphosphatidylcholine (DOPC) are poorly transported with delayed metabolism of Aβ oligomers. LPS can alter cells with POPC cell membrane characteristics by in.. View More»
