Deep learning augmented nanoplasmonic infrared sensor for structural protein biomarker-based detection of neurodegenerative diseases

Hilal Lashuel, Hatice Altug, Deepthy Kavungal, Rajasekhar Kolla, Pedro José Santana Ribeiro Magalhães

We introduce an infrared metasurface sensor based on plasmonic surface-enhanced infrared absorption spectroscopy combined with immunoassay, which detects alpha-synuclein, an early structural biomarker protein for neurodegenerative diseases with clinical sp ...

Deep Learning-Assisted Single-Molecule Detection of Protein Post-translational Modifications with a Biological Nanopore

Hilal Lashuel, Matteo Dal Peraro, Chan Cao, Lucien Fabrice Krapp, Simon Finn Mayer, Juan Francisco Bada Juarez, Anass Chiki, Pedro José Santana Ribeiro Magalhães

Protein post-translational modifications (PTMs) play a crucial role in countless biological processes, profoundly modulating protein properties on both spatial and temporal scales. Protein PTMs have also emerged as reliable biomarkers for several diseases. ...

Artificial intelligence-coupled plasmonic infrared sensor for detection of structural protein biomarkers in neurodegenerative diseases

Hilal Lashuel, Hatice Altug, Deepthy Kavungal, Rajasekhar Kolla, Pedro José Santana Ribeiro Magalhães

Diagnosis of neurodegenerative disorders (NDDs) including Parkinson's disease and Alzheimer's disease is challenging owing to the lack of tools to detect preclinical biomarkers. The misfolding of proteins into oligomeric and fibrillar aggregates plays an i ...

A NAC domain mutation (E83Q) unlocks the pathogenicity of human alpha-synuclein and recapitulates its pathological diversity

Hilal Lashuel, Anne-Laure Mahul Mellier, Sonia Donzelli, Ramanath Narayana Hegde, Pedro José Santana Ribeiro Magalhães

The alpha-synuclein mutation E83Q, the first in the NAC domain of the protein, was recently identified in a patient with dementia with Lewy bodies. We investigated the effects of this mutation on the aggregation of aSyn monomers and the structure, morpholo ...

Opportunities and challenges of alpha-synuclein as a potential biomarker for Parkinson's disease and other synucleinopathies

Hilal Lashuel, Pedro José Santana Ribeiro Magalhães

Parkinson's disease (PD), the second most common progressive neurodegenerative disease, develops and progresses for 10-15 years before the clinical diagnostic symptoms of the disease are manifested. Furthermore, several aspects of PD pathology overlap with ...

Revisiting the specificity and ability of phospho-S129 antibodies to capture alpha-synuclein biochemical and pathological diversity

Hilal Lashuel, Nicolas Jean Philippe Guex, Christian Iseli, Anne-Laure Mahul Mellier, Jonathan Jean-Pierre Ricci, Yllza Jasiqi, Anass Chiki, Sean Michael Deguire, Ritwik Burai, Melek Firat Altay

Antibodies against phosphorylated alpha-synuclein (aSyn) at 5129 have emerged as the primary tools to investigate, monitor, and quantify aSyn pathology in the brain and peripheral tissues of patients with Parkinson's disease and other neurodegenerative dis ...
