Improvements in electron cryo-tomography towards understanding virus surfing

, 2019
Electron cryo-tomography (cET), in combination with sub‑volume averaging (SVA), is a powerful technique for determining the structure of complex biological specimens that are not amenable to more traditional structure determination methods. In Chapter 1, SVA was used to achieve a sub-nanometre resolution structure of Herpes simplex virus 1 glycoprotein

Structural Basis of Shiga Toxin Neutralization by Human Antibodies Targeting Canonical Receptor‐Binding and Non‐Canonical Assembly Sites

Advanced Science, EarlyView.
Cryo‐electron microscopy structures reveal two distinct neutralization mechanisms of fully human monoclonal antibodies targeting the Shiga toxin 1a B subunit. RDS059 occludes the Gb3 receptor‐binding site, whereas RDS045 engages a lateral quaternary epitope to disrupt holotoxin assembly.

The architecture of membrane structures involved in hepatitis C virus genome replication revealed under close-to-native conditions by cryo-electron tomography [PDF]

Hepatitis C virus (HCV) infection induces extensive rearrangements of host cytoplasmic membranes, leading to the formation of multiple membranous structures that facilitate RNA replication.

Tau Aggregate Imaging and Transcriptomics of Alzheimer's Disease Brain at Different Stages of Disease

Advanced Science, EarlyView.
The protein aggregates and gene expression in the middle temporal gyrus (MTG) and somatosensory cortex (SOM) of the postmortem brains of 13 Alzheimer's disease patients were studied in detail, revealing that small hyperphosphorylated tau aggregates increase with Braak stage driven by microglial inflammation.

Integrative imaging and electron cryo-tomography of viral transport mechanisms

, 2016
To comprehensively understand a biological process or mechanism from molecule to cell it requires the combination of multiple techniques across a range of resolutions and scales. We currently rely on a variety of different approaches to highlight given aspects of biology that are then interlinked through interpretation.

Carbohydrate‐Mediated Cellular Uptake of Boronic Acid Hybrids In Cellulo and Insulin‐Deficient Zebrafish: Live Imaging and Application of Multiphoton FLIM

Advanced Science, EarlyView.
Boronic acid‐based fluorescent hybrids have been used as part of a versatile platform for real‐time metabolic bioimaging across cellular and organismal scales. Including glucose‐responsive imaging in living cells and in an insulin‐deficient vertebrate model, this work opens new opportunities for the development of precision diagnostics, metabolic ...

Water‐Soluble POSS Promotes Concurrent Coalescence and Crosslinking for Multiscale‐Reinforced, Coalescent‐Free Waterborne Coatings

Advanced Science, EarlyView.
Water‐soluble amine‐functionalized polyhedral oligomeric silsesquioxane promotes concurrent latex coalescence and crosslinking, allowing epoxy‐functional particles to form continuous films without added volatile coalescing agents. The resulting multiscale‐reinforced waterborne coatings combine high strength, toughness, optical transparency, scratch ...
