Laminin affects polymerization, depolymerization and neurotoxicity of Abeta peptide.

abstract：:Members of the neprilysin family of neutral endopeptidases (M13) are typically membrane-bound enzymes known to be involved in the extra-cellular metabolism of signalling peptides and have important roles during mammalian embryogenesis. In this study we show that membranes prepared from embryos of Drosophila melanogast...
