Generation of a human induced pluripotent stem cell line (INEUi001-A) from an amyotrophic lateral sclerosis/frontotemporal dementia patient with a C9ORF72 G4C2 genotype of <2 (GGGGCCG) and 10 repeats.

Human induced pluripotent stem cell (hiPSC) line INEUi001-A was reprogrammed from peripheral blood mononuclear cells (PBMC) using the lentiviral-hSTEMCCA-loxP vector. PBMCs were obtained from a 75- year-old female ALS/FTD disease patient carrying a heterozygous deletion within the C9ORF72 hexanucleotide repeat region resulting in a GGGGCCG sequence (∼1.16 repeats).

Generation of a human induced pluripotent stem cell line from a familial Alzheimer's disease PSEN1 T119I patient.

Human induced pluripotent stem cells (hiPSC) line FLENIi001-A was reprogrammed from dermal fibroblasts using the lentiviral-hSTEMCCA-loxP vector. Fibroblasts were obtained from a skin biopsy of a 72-year-old Caucasian male familial Alzheimer's disease patient carrying the T119I mutation in the PSEN1 gene. PSEN1 genotype was maintained and stemness and pluripotency confirmed in the FLENIi001-A hiPSC line.

A novel mutation in PSEN1 (p.T119I) in an Argentine family with early- and late-onset Alzheimer's disease.

Mutations in PSEN1 are the most common cause of early-onset Alzheimer's disease (AD). In this article, we present an Argentine family with autosomal dominant early- and late-onset AD. The proband and 6 family members were available for genetic testing and clinical and neuropsychological assessments.

Evaluation of Cerebrospinal Fluid Neurofilament Light Chain as a Routine Biomarker in a Memory Clinic.

Systematic evaluation of biomarkers in representative populations is needed to validate their clinical utility. In this work, we assessed the diagnostic performance of cerebrospinal fluid (CSF) neurofilament light chain (NfL) in a neurocognitive clinical setting. A total of 51 patients with different cognitive clinical syndromes and 11 cognitively normal individuals were evaluated in a memory clinic in Argentina.

In vitro growth and cell wall degrading enzyme production by Argentinean isolates of Macrophomina phaseolina, the causative agent of charcoal rot in corn.

Macrophomina phaseolina is a polyphagous phytopathogen, causing stalk rot on many commercially important species. Damages caused by this pathogen in soybean and maize crops in Argentina during drought and hot weather have increased due its ability to survive as sclerotia in soil and crop debris under non-till practices. In this work, we explored the in vitro production of plant cell wall-degrading enzymes [pectinases (polygalacturonase and polymethylgalacturonase); cellulases (endoglucanase); hemicellulases (endoxylanase) and the ligninolytic enzyme laccase] by several Argentinean isolates of M.

Analysis of C9orf72 in patients with frontotemporal dementia and amyotrophic lateral sclerosis from Argentina.

Pathologic expansion of the G4C2 repeat in C9orf72 is the main genetic cause of frontotemporal dementia (FTD) and amyotrophic lateral sclerosis (ALS). To evaluate the frequency of the G4C2 expansion in a Latin American cohort of FTD and ALS patients, we used a 2-step genotyping strategy. For FTD, we observed an overall expansion frequency of 18.
