Nanoplasmonic infrared biosensors enabling detection of misfolded protein biomarkers and drug screening for neurodegenerative diseases

Neurodegenerative diseases (NDDs), such as Parkinson's disease and Alzheimer's disease present a significant global health concern. The misfolding of proteins from native disordered monomeric forms into beta-sheet enriched aggregates of oligomers and fibri ...

O-GlcNAc forces an α-synuclein amyloid strain with notably diminished seeding and pathology

Hilal Lashuel, Yllza Jasiqi

Amyloid-forming proteins such alpha-synuclein and tau, which are implicated in Alzheimer's and Parkinson's disease, can form different fibril structures or strains with distinct toxic properties, seeding activities and pathology. Understanding the determin ...

Overexpression of human alpha-Synuclein leads to dysregulated microbiome/metabolites with ageing in a rat model of Parkinson disease

Joan Romani Aumedes, Hilal Lashuel, Yogesh Singh Chauhan, Florian Lang

Background Braak's hypothesis states that sporadic Parkinson's disease (PD) follows a specific progression of pathology from the peripheral to the central nervous system, and this progression can be monitored by detecting the accumulation of alpha-Synuclei ...

Pathological substrate of memory impairment in multiple system atrophy

Hilal Lashuel, Melek Firat Altay

Aims: Synaptic dysfunction in Parkinson's disease is caused by propagation of pathogenic alpha-synuclein between neurons. Previously, in multiple system atrophy (MSA), pathologically characterised by ectopic deposition of abnormal alpha-synuclein predomina ...

Capturing the heterogeneity of alpha-synuclein pathology in synucleinopathies

Melek Firat Altay

Synucleinopathies such as Parkinson's disease, dementia with Lewy bodies and multiple system atrophy (MSA) are detrimental neurodegenerative diseases. Alpha-synuclein (aSyn), the main aggregating protein found in the pathological inclusions of these ailmen ...

Retromer deficiency in Tauopathy models enhances the truncation and toxicity of Tau

Graham Knott, Evelyne Ruchti, Catherine Maclachlan, Brian Donal McCabe, Wei Jiao, Greta Limoni

Alteration of the levels, localization or post-translational processing of the microtubule associated protein Tau is associated with many neurodegenerative disorders. Here we develop adult-onset models for human Tau (hTau) toxicity in Drosophila that enabl ...

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 ...

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

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

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 ...

Enforced dimerization between XBP1s and ATF6f enhances the protective effects of the UPR in models of neurodegeneration

Hilal Lashuel, Sonia Donzelli

Alteration to endoplasmic reticulum (ER) proteostasis is observed in a variety of neurodegenerative diseases associated with abnormal protein aggregation. Activation of the unfolded protein response (UPR) enables an adaptive reaction to recover ER proteost ...

Clinical correlates of white matter lesions in Parkinson's disease using automated multi-modal segmentation measures

Tobias Kober, Bénédicte Marie Maréchal

Background: Age-related white matter lesions (WML) are common, impact neuronal connectivity, and affect motor function and cognition. In addition to pathological nigrostriatal losses, WML are also common co morbidities in Parkinson's disease (PD) that affe ...

To target Tau pathologies, we must embrace and reconstruct their complexities

Hilal Lashuel, Galina Limorenko

The accumulation of hyperphosphorylated fibrillar Tau aggregates in the brain is one of the defining hallmarks of Tauopathy diseases, including Alzheimer's disease. However, the primary events or molecules responsible for initiation of the pathological Tau ...

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 ...

Role of the FoxO3a Transcription Factor in alpha-synuclein Induced Neurodegeneration

Emilda Pino

Increased expression of α-synuclein and point mutations in its amino acid sequence play a causative role in familial forms of Parkinson's disease (PD). In addition, circumstances affecting the level of α-synuclein expression significantly increase the risk ...

Alterations in lysosomal and proteasomal markers in Parkinson's disease: relationship to alpha-synuclein inclusions

Patrick Aebischer

We explored the relationship between ubiquitin proteasome system (UPS) and lysosomal markers and the formation of alpha-synuclein (alpha-syn) inclusions in nigral neurons in Parkinson disease (PD). Lysosome Associated Membrane Protein 1(LAMP1), Cathepsin D ...
