A Live Cell Imaging‐Compatible Bioreactor for the Interrogation of Cellular Responses to Modulated Flow Conditions

Advanced Science, EarlyView.
An open‐source, low‐cost 3D perfusion system integrating bioprinted scaffolds and live‐imaging overcomes 2D culture limitations. Modeling the cerebrospinal fluid‐filled subarachnoid space, it reveals flow‐dependent focal adhesion kinase activation in meningothelial cells, demonstrating a powerful platform for studying mechanobiology and creating ...

Atomic-resolution structures of prion AGAAAAGA amyloid fibrils [PDF]

Published in [Amyloids: Composition, Functions and Pathology, Editors Irene P. Halcheck and Nancy R. Vernon, NOVA Science Publishers, Hauppauge, N.Y., March 1st 2012, ISBN 978-1-62100-538-4, hardcover], Chapter 10, pp.177-186, 2011
To the best of the author's knowledge, there is little structural data available on the AGAAAAGA palindrome in the hydrophobic region (113-120) of prion proteins due to the unstable, noncrystalline and insoluble nature of the amyloid fibril, although many experimental studies have shown that this region has amyloid fibril forming properties and plays ...

Structure-based inhibitors of amyloid beta core suggest a common interface with tau. [PDF]

, 2019
Alzheimer's disease (AD) pathology is characterized by plaques of amyloid beta (Aβ) and neurofibrillary tangles of tau. Aβ aggregation is thought to occur at early stages of the disease, and ultimately gives way to the formation of tau tangles which ...

Structure of amyloid-β (20-34) with Alzheimer's-associated isomerization at Asp23 reveals a distinct protofilament interface. [PDF]

, 2019
Amyloid-β (Aβ) harbors numerous posttranslational modifications (PTMs) that may affect Alzheimer's disease (AD) pathogenesis. Here we present the 1.1 Å resolution MicroED structure of an Aβ 20-34 fibril with and without the disease-associated PTM, L ...

Transient Interdomain Interactions Modulate the Monomeric Structural Ensemble and Self‐Assembly of Huntingtin Exon 1

Advanced Science, EarlyView.
Polyglutamine (polyQ) tract expansion (≥ 36 amino acids) within the N‐terminal region of the Huntingtin protein (Httex1) causes Huntington's disease (HD), for which the underlying causes are not well‐understood. The authors performed computer simulations to understand the cause of HD at the molecular level.

Antiparallel β‐Sheet as a Key Motif of Amyloid‐β Inhibitor Designed via Topological Peptide Reprogramming

Angewandte Chemie, EarlyView.
Targeting Amyloid‐β (Aβ) aggregation requires a peptide‐based approach that accounts for the structural heterogeneity of Aβ. Here, we employ topological reprogramming via disulfide bonds to stabilize antiparallel β‐sheets within the dimeric peptide.
