Structural analyses of fibrinogen amyloid fibrils

, 2007
Hereditary fibrinogen amyloidosis is characterized by deposition of amyloid fibrils in renal glomeruli. The subunit protein of the amyloid fibrils is a proteolytic fragment of the fibrinogen Aa-chain.

A Prodrug Approach for Activity‐Based Chemical Modulation toward Multiple Pathological Targets in Alzheimer's Disease

Small, EarlyView.
We present a pathology‐responsive, activity‐based prodrug strategy that tackles multiple hallmarks of Alzheimer's disease (AD). Rationally designed BE compounds convert under oxidative stress into redox‐active aminophenols, neutralizing ROS and redirecting both metal‐free and metal‐bound Aβ aggregation.

Decontamination of prions, prion-associated amyloid and inefectivity from surgical stainless steel - implications for the risk of iatrogenic transmission of CJD

, 2009
The physicochemical nature of the infectious agent in prion diseases creates asignificant challenge for decontamination services. It has been shown to be both resistant tostandard methods of decontamination, used to inactivate viruses and bacteria, and ...

Nanobodies as next‐generation targeting platforms: From discovery technologies to translational biomedicine

VIEW, EarlyView.
Nanobodies, derived from the variable domains of camelid heavy‐chain‐only antibodies, have emerged as transformative biomedical tools due to their nanoscale size, exceptional stability, and unique capacity to recognize cryptic epitopes. This review provides a comprehensive overview of the field, outlining the structural and biochemical features of ...

Design and commissioning of a new synchrotron beamline dedicated to X‐ray footprinting mass spectrometry

Journal of Synchrotron Radiation, EarlyView.
A dedicated beamline at the Advanced Light Source synchrotron has been opened and commissioned for X‐ray footprinting mass spectrometry.The structural biology method of X‐ray footprinting mass spectrometry (XFMS) is available at two national synchrotron beamlines in the USA: one at the Advanced Light Source (ALS) on the West Coast and the other at the ...

Increased expression of inflammasome signaling genes and proteins in selective brain regions in the intermediate stage of Alzheimer's disease

Brain Pathology, EarlyView.
Neuritic plaques increase in the intermediate stage of Alzheimer's neuropathological change. The intermediate stage of Alzheimer's disease was investigated by transcriptomics and immunohistochemistry. This revealed that inflammasome sensors NLRP1, NLRP3, and AIM2 oligomerize with ASC speck to form the inflammasome complex and initiate the downstream ...

Associations between TMEM106B C‐terminal fragment aggregation, age, and TDP‐43 or tau pathology

Brain Pathology, EarlyView.
TMEM106B C‐terminal fragment (CTF) aggregation represents an age‐associated, common, diffuse phenomenon emerging after midlife with a weak association with TDP‐43 or tau pathology. These findings suggest that TMEM106B fibrillization may define a distinct axis of protein aggregation in the aging human brain. Abstract Transmembrane protein 106B (TMEM106B)

New perspectives on VEGF signalling in Alzheimer's disease

Brain Pathology, EarlyView.
Emery et al. bring together findings from recent multi‐omic studies, including single‐cell mRNA analysis of human post‐mortem brain tissue, and proteomic analysis of matched CSF and blood samples in large clinical studies. The authors present evidence of the involvement of altered VEGF signalling in vascular and immune dysfunction and neurodegeneration

Human brain matters: Navigating the neuropathology of COVID‐19

Brain Pathology, EarlyView.
Severe COVID‐19 is associated with vascular dysregulation and chronic neuroinflammation, leading to axonal injury and neurodegeneration. In long COVID or PASC, persistent alterations in neuroimaging and biofluid biomarkers reflect ongoing neuronal damage and neuroinflammation, contributing to long‐term neurological symptoms including fatigue, cognitive
