Design of a prodromal screening study for subtypes in Parkinson’s Disease
Objective: To follow-up prodromal Parkinson’s Disease (PD) subtypes in a longitudinal cohort study, validating new biomarkers and ethical guidelines for early detection of PD. Background:…Multidimensional phenotyping of human stem cell-derived midbrain dopaminergic neurons from a SNCA triplication carrier for drug screening applications
Objective: We hypothesized that combining multiple Parkinson's disease (PD) relevant cellular phenotypes will increase the accuracy, stability, and usability of human midbrain dopaminergic (mDA) neuronal…Genetic stratification of motor and quality of life outcomes in Parkinson’s disease in the EARLYSTIM study
Objective: We identified (Weiss et al., 2016) that single nucleotide polymorphism (SNPs) of the alpha-synuclein gene (SNCA) predicted the motor effect of subthalamic nucleus stimulation (STN-DBS)…Phosphorylated α-synuclein at serine residue 129 decreased in Parkinson’s disease patients taking 250mg of daily niacin for six months
Objective: The main objective was to determine if α-synuclein could be modulated by niacin supplementation, contributing to improved Parkinson’s disease (PD) symptoms. Background: Niacin supplementation…An Unusual Case of Multiple Systems Atrophy with Long Disease Duration, Severe Gliosis, and Scant Synuclein Pathology
Objective: To describe a pathologically unusual case of Multiple systems atrophy (MSA) with severe widespread gliosis and neuronal loss with scant alpha-synuclein (aSyn) pathology. Background:…Double labeling alpha-synuclein in labial minor salivary glands in Parkinson’s disease and idiopathic RBD patients
Objective: To investigate the presence of α-Syn immunostaining in minor salivary gland biopsies (MSGB) from patients with idiopathic Parkinson's disease (PD), idiopathic Rapid Eye Movement…Mapping regional alpha-synuclein seeding capacity in Multiple System Atrophy
Objective: The objective of our work was to develop a novel high-throughput cell-free assay that allowed us to perform a comprehensive characterization of α-synuclein seeding…Lipid metabolism alterations in the lysosomal membrane promotes chaperone-mediated autophagy dysfunction and alpha-synuclein pathology in Parkinson’s disease associated to GBA
Objective: The objective of this study was to generate and characterize a new in vitro neuronal model of Parkinson's diseases associated to GBA (PD-GBA) that…Natural History of Probable MSA in India: A Prospective Cohort Study
Objective: We aimed to prospectively study the natural history of probable multiple system atrophy (MSA) including autonomic testing, survival analysis; and assess whether serum alpha-synuclein…Biofluid Biomarkers in Prodromal Parkinson’s Disease
Objective: To analyze biomarker signatures in biofluids in prodromal Parkinson’s disease (PD) to identify subjects at-risk to conversion and for progression. Background: Individuals at-risk for…
