Generation and characterization of human-derived iPSC lines from three pairs of monozygotic twins discordant for Parkinson's disease

Here, we describe the generation of six human induced pluripotent stem cell (iPSC) lines from dermal fibroblasts of three pairs of monozygotic twins discordant for PD. We used non-integrating Sendai virus and the iPSC lines were comprehensively characterized. These lines provide a valuable resource for studying molecular differences between the affected and unaffected monozygotic twin and their response to genetic and non-genetic factors that might be involved in the development of PD.

All iPSC lines have a normal karyotype, express pluripotent genes including POU5F1, NANOG, and show alkaline phosphatase activity, as well as the ability to differentiate into all three germ layers. These PD iPSC lines can be used for disease mod...

Khabarova, D.A. Rzaev, S.M. Zakian, S.P. MedvedevAbstractStudying Parkinson's disease (PD), one of the most common neurodegenerative disorders worldwide, requires different model systems, including patient-specific induced pluripotent stem cell lines. With the help of non-integrating episomal vectors the IPSC lines ICGi015-A and ICGi015-B were generated from blood mononuclear cells of PD patient, carrying three SNPs, associated with PD dev...

A bacterial artificial chromosome-based homologous recombination (BAC-based HR) system was utilized for gene therapy of LRRK2 G2019S-mutant induced pluripotent stem cells (iPSCs) produced by reprogramming episomal vectors. The gene-corrected iPSCs retained typical pluripotency required for their spontaneous differentiation into differentiated cell...

We describe generation of human induced pluripotent stem cell (hiPSC) lines of three unrelated idiopathic late onset Parkinson disease patients and two healthy controls above 60 years of age without neurological diseases nor Ashkenazi ancestry. Human iPSC were derived from peripheral blood-erythroblasts using integration free episomal plasmids carrying four reprogramming factors OCT4, SOX2, c-MYC, KLF4 and BCL-XL. The hiPSC lines were characterized according to established criteria.

Abstract Parkinson's disease (PD) and frontotemporal dementia/amyotrophic lateral sclerosis (FTD/ALS) are insidious and incurable neurodegenerative diseases that represent a significant burden to affected individuals, caregivers, and an ageing population. Both PD and FTD/ALS are defined at post mortem by the presence of protein aggregates and the loss of specific subsets of neurons. We examine here the crucial role of lysosome dysfunction in these diseases and discuss recent evidence for converging mechanisms. This review draws upon multiple lines of evidence from genetic studies, human tissue, induced pluripotent...

In this study, we hypothesized that moderately and chronically reducing ACh could attenuate the deleterious effects of aging on NMJs and skeletal muscles. To test this hypothesis, we analyzed NMJs and muscle fibers from heterozygous transgenic mice with reduced expression of the vesicular ACh transporter (VAChT), VKDHet mice, which present with approximately 30% less synaptic ACh compared to control mice. Because ACh is constitutively decreased in VKDHet, we first analyzed developing NMJs and muscle fibers. We found no obvious morphological or molecular differences between NMJs and muscle fibers of VKDHet and contro...
