Relationship Between Alpha-Synuclein Aggregation Profiles, Imaging Biomarkers, and Disease Severity in a Phase 2 Study of ATH434 in MSA
Objective: To investigate the relationships between α-synuclein aggregation profiles, imaging biomarkers, and UMSARS I scores in the ATH434-201 Phase 2 study. Background: Multiple system atrophy…Atrophy In Multiple System Atrophy Relates To Mitochondrial And Oligodendrocytic Processes
Objective: To investigate the gene expression and neurobiological underpinnings of brain atrophy in MSA using imaging transcriptomics and PET-based molecular annotation Background: The biological mechanisms…Metabolic Patterns in Multiple System Atrophy: Brain Network Insights from Spatial ICA of FDG-PET
Objective: This study employs spatial independent component analysis (ICA) on 18F-fluorodeoxyglucose (FDG)-PET imaging to decompose metabolic heterogeneity in Multiple system atrophy (MSA), identifying key brain…Developing a novel Disease-Specific iPSC Model for Studying MSA Pathogenesis
Objective: This study aims to develop a human iPSC-derived oligodendrocyte (iPSC-OL) model to investigate cell-specific disease mechanisms in MSA. Specifically, we seek to:a)Generate MSA patient-derived…Alpha-Synuclein Promotes the Expression and Release of Neurofilament Light Chain from Oligodendrocytes in Multiple System Atrophy
Objective: This study aims to determine the Neurofilament light chain (NfL) expression in oligodendrocytes, investigate whether excess α-synuclein (α-syn) impacts NfL expression, release, and functions…Absence of identifiable neuropathological correlates of cognitive impairment in multiple system atrophy
Objective: To analyze neuropathological correlates of cognitive impairment in multiple system atrophy (MSA) and characterize the affected cognitive domains. Background: Current MSA census criteria delineate…Novel Multiple System Atrophy Subtypes Identified Using Unsupervised Machine Learning Algorithms
Objective: To identify a novel disease subtype of multiple system atrophy (MSA) by applying machine learning algorithms to a large cohort of autopsy-confirmed MSA. Background:…Alpha Synuclein Seeding Activity Drives Disease Heterogeneity in an Animal Model of Multiple System Atrophy
Objective: To examine the impact of multiple system atrophy (MSA) brain-derived alpha synuclein (αSyn) with diverse seeding activities in an inoculation-based animal model. Background: We…Description possible enviromental exposure in AMS Latin America population
Objective: To identify possible risk factors such as environmental exposures in subjects diagnosed with MSA from referral centres in Latin America (Pan-American MSA Study Group)…The differential transcriptomic signatures of substantia nigra in Parkinson disease and Multiple system atrophy
Objective: To investigate transcriptomic signatures of Parkinson's disease (PD) and the Parkinsonian subtype of Multiple System Atrophy (MSA-P) in the substantia nigra pars compacta (SNpc).…
