Seeded aggregation and toxicity of {alpha}-synuclein and tau: cellular models of neurodegenerative diseases.
The deposition of amyloid-like filaments in the brain is the central event in the pathogenesis of neurodegenerative diseases. Here we report cellular models of intracytoplasmic inclusions of α-synuclein, generated by introducing nucleation seeds into SH-SY5Y cells with a transfection reagent. Upon introduction of preformed seeds into cells overexpressing α-synuclein, abundant, highly filamentou...
متن کاملTau Enhances α-Synuclein Aggregation and Toxicity in Cellular Models of Synucleinopathy
BACKGROUND The simultaneous accumulation of different misfolded proteins in the central nervous system is a common feature in many neurodegenerative diseases. In most cases, co-occurrence of abnormal deposited proteins is observed in different brain regions and cell populations, but, in some instances, the proteins can be found in the same cellular aggregates. Co-occurrence of tau and α-synucle...
متن کاملAberrant cleavage of TDP-43 enhances aggregation and cellular toxicity.
Inclusions of TAR DNA-binding protein-43 (TDP-43), a nuclear protein that regulates transcription and RNA splicing, are the defining histopathological feature of frontotemporal lobar degeneration with ubiquitin-positive inclusions (FTLD-Us) and sporadic and familial forms of amyotrophic lateral sclerosis (ALS). In ALS and FTLD-U, aggregated, ubiquitinated, and N-terminally truncated TDP-43 can ...
متن کاملToxicity of Nanoparticles and an Overview of Current Experimental Models
Nanotechnology is a rapidly growing field having potential applications in many areas. Nanoparticles (NPs) have been studied for cell toxicity, immunotoxicity, and genotoxicity. Tetrazolium-based assays such as MTT, MTS, and WST-1 are used to determine cell viability. Cell inflammatory response induced by NPs is checked by measuring inflammatory biomarkers, such as IL-8, IL-6, and tumor necrosi...
متن کاملfunctional study of p0 proteins of two cereal yellow dwarf viruses (cydv-rpv and cydv-rps) and identification of their cellular partner
نقش سرکوبگری پروتئین p0 در دو پولروویروس کوتولگی زردی غلات cydv-rpv) و (cydv-rps، متفاوت در شدت بیماریزایی، مورد مطالعه قرار گرفت. نتایج نشان داد که هر دو پروتئین p0 p0cy-rpv) و (p0cy-rps قادر به سرکوب خاموشی آر ان ای ایجاد شده توسط ترادف های تراژن سنس و تکرار معکوس در n. benthamiana هستند. نشان داده شد که هر دو پروتئین p0 می توانند تخریب پروتئین argonaute-1 را تسهیل کنند. علاوه بر این، تمایل م...
