Background: A oligomers are major players in Alzheimer disease, but the tools for their detection are not satisfactory. Results: We developed a SPR-based immunoassay and a test in C. elegans, specifically identifying toxic oligomers. Conclusion: These methods allow study of the effects of mutations or drugs on A oligomerization. Significance: The S...
Article
A growing number of important human diseases are associated with the aggregation and deposition of incorrectly folded proteins in the form of highly structured amyloid fibrils. The aggregation process involves the formation of intermediate oligomeric assemblies with toxic properties. There are many commonalities among the different amyloid diseases...

Selenoprotein N (SEPN1) is a protein of the endoplasmic reticulum (ER) whose inherited defects originate SEPN1-related myopathy (SEPN1-RM). Here, we identify an interaction between SEPN1 and the ERstress-induced oxidoreductase ERO1A. SEPN1 and ERO1A, both enriched in mitochondria-associated membranes (MAMs), are involved in the redox regulation of...

Background Brain injury and neurological deficit are consequences of cardiac arrest (CA), leading to high morbidity and mortality. Peripheral activation of the kynurenine pathway (KP), the main catabolic route of tryptophan metabolized at first into kynurenine, predicts poor neurological outcome in patients resuscitated after out‐of‐hospital CA. He...

The formation of neurofibrillary tangles and amyloid plaques accompanies the progression of Alzheimer’s disease (AD). Tangles are made of fibrillar aggregates formed by the microtubule-associated protein tau, while plaques comprise fibrillar forms of amyloid-β (Aβ). Both form toxic oligomers during aggregation, and are thought to interact synergist...

Solid tumors are often characterized by a hypoxic microenvironment which contributes, through the hypoxia-inducible factor HIF-1, to the invasion-metastasis cascade. Endoplasmic reticulum (ER) stress also leads tumor cells to thrive and spread by inducing a transcriptional and translational program, the Unfolded Protein Response (UPR), aimed at res...
