Discriminative adsorption of amphiphilic monolayer protected gold nanoparticles on amyloid fibers

This thesis presents a systematic study of how different types monolayer-protected AuNPs interact with amyloid fibers. We report a class of amphiphilic gold nanoparticles capable of adsorbing onto specific surface features on these types of protein fibers. ...

Hyperpolarized Water to Study Protein-Ligand Interactions

Geoffrey Bodenhausen, Aurélien Bornet, Sami Jannin, Jonas Milani, Basile Vuichoud, Quentin Chappuis

The affinity between a chosen target protein and small molecules is a key aspect of drug discovery. Screening by popular NMR methods such as Water-LOGSY suffers from low sensitivity and from false positives caused by aggregated or denatured proteins. This ...

Modeling and Engineering Proteins Thermostability

Hasan Pezeshgi Modarres

Enzymes have evolved during millions of years to become efficient catalysts for specific biochemical reactions within a specific range of working conditions in the cellular environment. The activity of an enzyme is directly related to its folded structure ...

Genetic Mouse Models of Neurodegenerative Diseases

Darren Moore, Alzbeta Trancikova, David Ramonet Jimenez

Neurodegenerative diseases are generally characterized by the selective degeneration of particular neuronal populations and the accumulation of abnormal or aggregated proteins within, but occasionally external to, neurons in affected brain regions. These d ...

Understanding amyloid aggregation by statistical analysis of atomic force microscopy images

Giovanni Dietler, Paolo De Los Rios, Jérôme Flakowski, Raffaele Mezzenga

The aggregation of proteins is central to many aspects of daily life, including food processing, blood coagulation, eye cataract formation disease and prion-related neurodegenerative infections[1–5]. However, the physical mechanisms responsible for amyloid ...

Mini review on the structure and supramolecular assembly of VDAC

The Voltage Dependent Anion Channel (VDAC) is the most abundant protein in the outer membrane of mitochondria. This strategic localization puts it at the heart of a great number of phenomena. Its recent implication in apoptosis is an example of the major i ...

Impact of phosphorylation of alpha-synuclein in Parkinson's disease

Samareh Azeredo da Silveira Lajaunias

Parkinson's disease (PD) is characterized by the degeneration of dopamineric neurons of the substantia nigra pars compacta projecting to the striatum, and by the deposition of cytoplasmic protein inclusions. It is further defined by the persistent presence ...

On the origin of the boson peak in globular proteins

Paolo De Los Rios, Francesco Piazza

We study the boson peak phenomenology experimentally observed in globular proteins by means of elastic network models. These models are suitable for an analytic treatment in the framework of Euclidean random matrix theory, whose predictions can be numerica ...

Glasslike structure of globular proteins and the boson peak

Paolo De Los Rios, Francesco Piazza

Vibrational spectra of proteins and topologically disordered solids display a common anomaly at low frequencies, known as boson peak. We show that such feature in globular proteins can be deciphered in terms of an energy landscape picture, as it is for gla ...
