Analysis of iPSC lines derived from a PD patient with SNCA triplication and an unaffected first-degree relative. Triplication of SNCA, encoding α-synuclein, causes an aggressive form of PD. Results provide insight into the mechanistic basis of neurodegeneration caused by α-synuclein dysfunction.

(Submitter supplied) A major barrier to research on Parkinson’s disease (PD) is inaccessibility of diseased tissue for study. One solution is to derive induced pluripotent stem cells (iPSCs) from patients with PD and differentiate them into neurons affected by disease. We created an iPSC model of PD caused by triplication of SNCA encoding α-synuclein. α-Synuclein dysfunction is common to all forms of PD, and SNCA triplication leads to fully penetrant familial PD with accelerated pathogenesis. more...

(Submitter supplied) Analysis of whole genome expression in control and patients with Parkinsons disease iPSC lines. The hypothesis tested in present study was that deficient GBA, SNCA, LRRK2 and PARKIN expression can be used for disease modeling by their affects on multiple pathways. These results provide information on relationship between PD genes and mitochondria related gene expression.

(Submitter supplied) We established induced pluripotent stem cells (iPSC) from centrenarians by retroviral transduction of primary human fibroblasts. To show the similarity between 201B7 iPSC and 100-1 #16 iPSC (induced pluripotent stem cells from centenarian), this experiment was designed.

(Submitter supplied) Purpose: The goal of this study is to compare the NGS-derived from transcriptome profiling (RNA-seq) of human iPSC, human iPSC-derived astrocytes from control and Parkinson’s disease LRRK2 G2019S, and human commercial astrocytes to gain insight into the identity of human iPSC-derived astrocytes in vitro during the differentiation process. Total RNA was assayed for quantity and quality using Qubit® RNA HS Assay (Life Technologies) and RNA 6000 Nano Assay on a Bioanalyzer 2100. more...

(Submitter supplied) Althougha-synuclein is implicated in the pathogenesis of Parkinson’s disease and related disorders, it remains unclear whether specific conformations or levels ofa-synuclein assemblies are toxic and how they cause progressive loss of human dopaminergic neurons. To address this issue, we used iPSC-derived dopaminergic neurons with a-synuclein triplication or controls where endogenous a-synuclein was imprinted into synthetic or disease-relevant conformations. more...

(Submitter supplied) SNCA, the first gene associated with Parkinson’s disease, encodes the α-synuclein protein, the predominant component within pathological inclusions termed Lewy bodies. We use 3D midbrain organoids, differentiated from human induced pluripotent stem cells derived from patients carrying a triplication of the SNCA gene and from CRISPR/Cas9 corrected isogenic control iPSCs. These human midbrain organoids recapitulate key features of α-synuclein pathology observed in the brains of patients with synucleinopathies. more...

(Submitter supplied) Aggregated α-synuclein (α-SYN) proteins, encoded by the SNCA gene, are hallmarks of Lewy body disease (LBD), affecting multiple brain regions. However, the specific mechanisms underlying α-SYN pathology in cortical neurons, crucial for LBD-associated dementia, remain unclear. Here, we generated human cortical LBD models by differentiating induced pluripotent stem cells (iPSCs) from SNCA triplication LBD patients into cerebral organoids and observed increased levels of pathological α-SYN in these organoids. more...
