Deskripsi
Formation of amyloid-beta (Aβ) oligomer pores in the membrane of neurons has been proposed to explain neurotoxicity in Alzheimer´s disease. Here authors present the 3D- structure of an Aβ oligomer formed in a membrane mimicking environment and observe that Aβ tetramers and octamers inserted into lipid bilayers as well-defined pores.
