Bank Vole Prion Protein As an Apparently Universal Substrate for RT-QuIC-Based Detection and Discrimination of Prion Strains.

PLoS Pathogens, 2015
Prions propagate as multiple strains in a wide variety of mammalian species. The detection of all such strains by a single ultrasensitive assay such as Real Time Quaking-induced Conversion (RT-QuIC) would facilitate prion disease diagnosis, surveillance ...

A single ultrasensitive assay for detection and discrimination of tau aggregates of Alzheimer and Pick diseases

Acta Neuropathologica Communications, 2020
Multiple neurodegenerative diseases are characterized by aggregation of tau molecules. Adult humans express six isoforms of tau that contain either 3 or 4 microtubule binding repeats (3R or 4R tau).

Enhanced Sensitivity of a Modified Quaking‐Induced Conversion Diagnostic Test for the Broad Detection of Sporadic and Inherited Prion Diseases: A Retrospective Study

Annals of Neurology, Volume 99, Issue 5, Page 1303-1314, May 2026.
Objective Quaking‐induced conversion (QuIC) tests, which detect prion‐seeding activity in cerebrospinal fluid (CSF), have markedly advanced the antemortem diagnosis of prion diseases such as Creutzfeldt‐Jakob disease (CJD). These tests provide high diagnostic accuracy and enable timely differentiation from other rapidly progressive neurodegenerative ...

Myelin Oligodendrocyte Glycoprotein Antibody‐Associated Cerebral Cortical Encephalitis: A Comparative Study With Antibody‐Negative and Non‐MOG Antibody‐Positive Cortical Encephalitis in Chinese Adults

CNS Neuroscience &Therapeutics, Volume 32, Issue 5, May 2026.
MOG antibody‐associated cortical encephalitis (MOG‐CCE) presents a distinct clinical phenotype characterized by seizure‐dominant onset, unilateral cortical lesions, and favorable immunotherapy response, highlighting the diagnostic and prognostic value of antibody profiling in autoimmune cortical encephalitis.

Evidence for different seeding activities of misfolded tau in classical and rapidly progressive Alzheimer's disease

Brain Pathology, Volume 36, Issue 3, May 2026.
The study analyzed the seeding activity of misfolded tau protein in Alzheimer's disease and rapidly progressive Alzheimer's disease patients and provides evidence for the existence of different tau assemblies supported by differences in cellular toxicity and morphology of thioflavin T‐positive real‐time quaking‐induced conversion products.

Quaking-induced conversion of prion protein on a thermal mixer accelerates detection in brains infected with transmissible spongiform encephalopathy agents.

PLoS ONE, 2019
Detection of misfolded prion protein, PrPTSE, in biological samples is important to develop antemortem tests for transmissible spongiform encephalopathies (TSEs).

Seed Amplification Assays for Parkinson's Disease: A Review of α‐Synuclein Assays in Body Fluids and Tissues

Journal of Neurochemistry, Volume 170, Issue 5, May 2026.
Background: Parkinson's disease (PD) diagnosis is hindered by late motor symptom onset and low specificity of clinical assessments. This systematic review and meta‐analysis evaluates α‐synuclein seed amplification assays (SAAs) for PD and related synucleinopathies. Main Results: SAAs, including real‐time quaking‐induced conversion (RT‐QuIC) and protein

Variably Protease‐Sensitive Prionopathy: Two New Cases With Motor Neuron‐Dementia Syndrome

Annals of Clinical and Translational Neurology, Volume 13, Issue 4, Page 827-833, April 2026.
ABSTRACT We describe two patients with variably protease‐sensitive prionopathy (VPSPr) who developed progressive upper motor neuron symptoms, insomnia, behavioral and cognitive decline, compatible with primary lateral sclerosis associated with frontotemporal dementia (FTD).

Tracking tau and cellular responses in human iPSC‐microglia: from uptake to seedable secretion, including in extracellular vesicles

Alzheimer's &Dementia, Volume 22, Issue 4, April 2026.
Abstract INTRODUCTION Microglia have been implicated in the templated spread of tau aggregates in tauopathies through mouse studies. However, it is unclear whether these findings translate to human disease. METHODS We challenged human induced pluripotent stem cell (iPSC)‐derived microglia‐like‐cells (iMGL) with monomeric and fibrillar recombinant tau ...

The Phenotypic Spectrum of Sporadic Creutzfeldt‐Jakob Disease Cortical Subtype

Annals of Neurology, Volume 99, Issue 4, Page 883-896, April 2026.
Objective The objective of this study was to characterize the phenotypic spectrum of the rare sporadic Creutzfeldt‐Jakob disease cortical subtype (sCJDMM/MV2C) in a large multicentric autopsy cohort. Methods We evaluated clinical histories, biofluid markers, brain diffusion‐weighted (DW)‐magnetic resonance imaging (MRI), and electroencephalogram (EEG ...
