Amyloid-β (Aβ) is a key pathological contributor to Alzheimer's disease. Gremer et al. used cryoelectron microscopy data to build a high-quality de novo atomic model of Aβ fibrils (see the Perspective by Pospich and Raunser). The complete structure reveals all 42 amino acids (including the entire N terminus) and provides a structural basis for understanding the effect of several disease

T1 - Identification of on- And off-pathway oligomers in amyloid fibril formation. AU - Dear, Alexander J. AU - Meisl, Georg. AU - Šarić, Anđela The α-syn amyloid fibril structure shows two protofilaments intertwining along an approximate 2 1 screw axis into a left-handed helix. Each protofilament features a Greek key-like topology. Remarkably, five out of the six early-onset PD familial mutations are located at the dimer interface of the fibril (H50Q, G51D, and A53T/E) or involved in the stabilization of the protofilament (E46K). Amyloid fibril polymorphism.

However, structural details of misfolded Aβ(1-42) have remained elusive. Here we present the atomic model of an Aβ(1-42) amyloid fibril, from solid-state NMR (ssNMR) data. It displays triple parallel-β-sheet segments that differ from reported structures of Aβ(1-40) fibrils.

Ivanova MI, Sawaya MR, Gingery M, Attinger A, Eisenberg D. Proc Natl Acad Sci U S A. 2004 Jul 20;101(29):10584-9. Moreover, some short peptides possess the same amyloid properties as full length proteins (Balbirnie et al., 2001; Tenidis et al., 2000), and some very short specific stretches have been considered to be the regions responsible for aggregation, as they can change the amyloidogenic propensities of polypeptides by facilitating or inhibiting fibril formation (Ivanova et al., 2004; Ventura et al An atomic-resolution structure of a cross-β amyloid fibril and its constituent self-assembling subunits has proved elusive to structural biology. Such a structure is of great interest, because the thermodynamic and kinetic properties of amyloid fibrils, as well as their frequently adverse effects on cellular homeostasis leading to disease, are linked to the details of their morphological Immunohistochemistry - Free Floating - Anti-Amyloid Fibril antibody [mOC87] - Conformation-Specific (ab201062) Image courtesy of Professor Charles Glabe, UC Irvine Immunohistochemical staining of human brain tissue from a patient with a diagnosis of Alzheimers disease, male, 81 years, 5 hour post mortem index, tangle stage 5, plaque stage B, mini mental status exam score 12.
