Computational and Structural Biotechnology Journalβ-Structure-rich amyloid fibrils are hallmarks of several diseases, including Alzheimer’s (AD), Parkinson’s (PD), and type 2 diabetes (T2D). While amyloid fibrils typically consist of parallel β-sheets, the anti-parallel β-hairpin is a structural motif ...

Membrane permeabilization by Islet Amyloid Polypeptide
, 2009 Membrane permeabilization by Islet Amyloid Polypeptide (IAPP) is suggested to be the main mechanism for IAPP-induced cytotoxicity and death of insulin-producing -cells in type 2 diabetes mellitus (T2DM).

The role and therapeutic targeting of α-, β- and γ-secretase in Alzheimer's disease [PDF]
, 2015 Alzheimer's disease (AD) is the most common form of dementia in the elderly and its prevalence is set to increase rapidly in coming decades. However, there are as yet no available drugs that can halt or even stabilize disease progression. One of the main

The FEBS Journal, EarlyView.Investigated mutations in transthyretin (TTR) disrupt the F87‐centered hydrophobic core that stabilizes its tetrameric structure. The mild I107V mutation weakens inter‐chain packing, while H88R fully abolishes tetramer formation, yielding a monomeric, aggregation‐prone form. Structural, biophysical, and computational analyses reveal that both mutations

Utilization and Prognosis of Cardiac Device Implantation in AL Versus ATTR Amyloidosis
Pacing and Clinical Electrophysiology, EarlyView.ABSTRACT Introduction Cardiac amyloidosis can cause congestive heart failure, arrhythmias, and heart blocks, which frequently require cardiac device implantation (CDI). However, the differences between light chain (AL) amyloidosis and transthyretin (ATTR) amyloidosis CDI requirements are unknown. Methods A retrospective analysis was conducted using the

Cross-seeding of prions by aggregated α-synuclein leads to transmissible spongiform encephalopathy.
PLoS Pathogens, 2017 Aggregation of misfolded proteins or peptides is a common feature of neurodegenerative diseases including Alzheimer's, Parkinson's, Huntington's, prion and other diseases.

Desmin forms toxic, seeding-competent amyloid aggregates that persist in muscle fibers [PDF]
, 2019 Desmin-associated myofibrillar myopathy (MFM) has pathologic similarities to neurodegeneration-associated protein aggregate diseases. Desmin is an abundant muscle-specific intermediate filament, and disease mutations lead to its aggregation in cells ...

LRP1 Has a Predominant Role in Production over Clearance of Aβ in a Mouse Model of Alzheimer's Disease. [PDF]
, 2019 The low-density lipoprotein receptor-related protein-1 (LRP1) has a dual role in the metabolism of the amyloid precursor protein (APP). In cellular models, LRP1 enhances amyloid-β (Aβ) generation via APP internalization and thus its amyloidogenic ...

Journal of Peptide Science, Volume 32, Issue 5, May 2026.Residues with backbone N‐amination have been introduced into a region of parallel β‐sheet secondary structure. Contrary to predictions, the N‐amination of Trp9 or Phe33 did not give an increase in the thermal stability of DS119. MD simulations suggest this is due to the highly fluctuating nature of the β‐sheet region. ABSTRACT The miniprotein DS119 has
