Autophagy and LRRK2 in the Aging Brain

Autophagy is a highly conserved process by which long-lived macromolecules, protein aggregates and dysfunctional/damaged organelles are delivered to lysosomes for degradation. Autophagy plays a crucial role in regulating protein quality control and cell ho ...

alpha-Synuclein O-GlcNAcylation alters aggregation and toxicity, revealing certain residues as potential inhibitors of Parkinson's disease

Hilal Lashuel, Anne-Laure Mahul Mellier

A compelling link is emerging between the posttranslational modification O-GlcNAc and protein aggregation. A prime example is alpha-synuclein, which forms toxic aggregates that are associated with neurodegeneration in Parkinson's and related diseases. alph ...

Calpain-mediated tau fragmentation is altered in Alzheimer's disease progression

Andrea Pfeifer, Andreas Muhs

The aggregation of intracellular tau protein is a major hallmark of Alzheimer's disease (AD). The extent and the stereotypical spread of tau pathology in the AD brain are correlated with cognitive decline during disease progression. Here we present an in-d ...

Polyglutamine expansion affects huntingtin conformation in multiple Huntington’s disease models

Hilal Lashuel, Sean Michael Deguire, Lara Petricca

Conformational changes in disease-associated or mutant proteins represent a key pathological aspect of Huntington's disease (HD) and other protein misfolding diseases. Using immunoassays and biophysical approaches, we and others have recently reported that ...

AFM-Based Single Molecule Techniques: Unraveling the Amyloid Pathogenic Species

Giovanni Dietler, Andrea Cerreta, Francesco Simone Ruggeri

Background: A wide class of human diseases and neurodegenerative disorders, such as Alzheimer's disease, is due to the failure of a specific peptide or protein to keep its native functional conformational state and to undergo a conformational change into a ...

Microtubule-Binding R3 Fragment from Tau Self-Assembles into Giant Multistranded Amyloid Ribbons

Raffaele Mezzenga, Hilal Lashuel, Nadine Aït Bouziad

Tau protein and its fragments self-assemble into amyloid fibrils in the presence of polyanions, such as heparin. By combining microscopy, scattering, and spectroscopy techniques, we studied the aggregation of the 26-mer Tau-derived peptide alone, Tau306-32 ...

A critical concentration of N-terminal pyroglutamylated amyloid beta drives the misfolding of Ab1-42 into more toxic aggregates

Giovanni Dietler, Francesco Simone Ruggeri

A wide consensus based on robust experimental evidence indicates pyroglutamylated amyloid-beta isoform (A beta pE3-42) as one of the most neurotoxic peptides involved in the onset of Alzheimer's disease. Furthermore, A beta pE3-42 co-oligomerized with exce ...
