Dogs Never Gets Prion Diseases. The Entropic Landscape Analysis of Prion Proteins Answers Why. [PDF]

, 2009
The Entropic Landscape Analysis was applied to the prion protein sequences of various mammals in order to detect potential sites of variants that would be responsible for the susceptibility of prion disease infection.

Toxic mechanisms of amyloid oligomers and therapeutic strategies

Protein Science, Volume 35, Issue 4, April 2026.
Abstract Amyloid oligomers are increasingly recognized as the major toxic contributors across protein‐misfolding disorders. In this review, we cover mechanistic evidence showing how these transient and structurally heterogeneous oligomers disrupt cellular homeostasis by: (i) permeabilizing lipid membranes and forming ion‐conducting pores; (ii ...

In vitro, cellular and in vivo studies of amyloid oligomers structure and toxicity: Challenges and advances

Protein Science, Volume 35, Issue 4, April 2026.
Abstract Oligomeric assemblies of amyloidogenic proteins, such as Aβ, tau, α‐synuclein, amylin, transthyretin, and TDP‐43, are increasingly recognized as key drivers of cellular dysfunction across a range of neurodegenerative and systemic disorders.

In silico peptide self‐assembly reveals the importance of N‐terminal motifs and the inhibition mechanism of the mutation L38M in α‐synuclein fibrillation

Protein Science, Volume 35, Issue 4, April 2026.
Abstract Alpha‐synuclein (αSyn) is a presynaptic protein associated with several neurodegenerative diseases. While the non‐amyloid component (NAC) region of the αSyn sequence (residues 65–90) forms the core of all αSyn fibrils, recent findings suggest that the flanking regions play a key role in initiating or preventing amyloid formation. Two motifs in

Scalable assay to identify inhibitors of prion‐like propagation of protein misfolding as potential therapeutics for neurodegeneration

Protein Science, Volume 35, Issue 4, April 2026.
Abstract Protein misfolding is linked to many neurodegenerative diseases. In some cases, misfolding can propagate through a prion‐like mechanism whereby natively folded molecules are converted into more copies of the misfolded isoform. Prion‐like propagation of misfolding is an attractive therapeutic target, but difficulties with assaying conversion ...

NOTCH3 CADASIL Variant Receptor Aggregation Requires NOTCH3 Wild‐Type Receptors: Identification of Highly Selective Inhibitors That Block the Process

The FASEB Journal, Volume 40, Issue 6, 31 March 2026.
CADASIL is the major cause of early‐onset stroke and cognitive dysfunction, including dementia. It is caused by mutations in the NOTCH3 receptor that result in the formation of protein aggregates in the small vessel walls of the brain. We demonstrated that NOTCH3 CADASIL variant receptor aggregation is strictly dependent on interactions with NOTCH3 ...

Doppel as an early‐stage biomarker promoting EMT and dissemination in ovarian cancers

International Journal of Cancer, Volume 158, Issue 6, Page 1755-1768, 15 March 2026.
What's new? Existing biomarkers for ovarian cancer (OC) lack the sensitivity and specificity needed to consistently distinguish the malignancy from non‐ovarian influences and other cancers. Here, the authors explored the ability of the prion‐like protein Doppel, normally found in the male testes, to detect OC.

Acute stress and multicellular development alter the solubility of the Dictyostelium Sup35 ortholog ERF3

Microbiology Spectrum
Among sequenced organisms, the genome of Dictyostelium discoideum is unique in that it encodes for a massive amount of repeat-rich sequences in the coding region of genes.

ACAT1, Cav-1, and PrP expression in brains and skin fibroblasts from Sarda breed sheep with scrapie-resistant and scrapie-susceptible genotype. [PDF]

Scrapie is an infective ovine neurodegenerative disease; the only identified component of the infectious agent being an aberrant isoform (PrPSc) of the cellular prion protein (PrPC). So far, no means for ante-mortem diagnosis are available for Scrapie as
