tdp-43 aggregation

Mutations that disrupt TDP-43 RNA binding may contribute to pathogenic mislocalization and aggregation in ALS and FTLD-TDP [31].

TAR DNA binding protein (TDP-43) has been found to be a major component of inclusion bodies in motor neurons of ALS patients. Inclusion bodies are protein aggregates considered a pathological hallmark of neurodegeneration. Our group and eight independent research groups screened TDP-43 for mutations.

Our study addressed the impact of selected ALS-associated genes on TDP-43 aggregation behavior in wild-type and aggregation prone TDP-43 in vitro cell 

Intraneuronal aggregation of TDP-43 is seen in 97% of all amyotrophic lateral sclerosis cases and occurs by a poorly understood mechanism.

TDP-43 is a nuclear RNA-binding protein that forms neuronal cytoplasmic inclusions in two major neurodegenerative diseases, ALS and FTLD.

2021. 12. 8. · In some neurodegenerative diseases, a protein called TDP-43 forms aggregates in the brain, resulting in neuronal cell death. The structure of these aggregates and their

TAR DNA binding protein 43 (TDP-43) is a nucleic acid binding protein involved in RNA-related metabolism. Aggregated TDP-43 has been identified as a 

2022. 9. 6. · Dysfunction and aggregation of the RNA-binding protein, TDP-43, is the unifying hallmark of amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD). Mechanisms and relative contributions of concurrent TDP-43 nuclear depletion, cytoplasmic accumulation, and post-translational modification to neurodegeneration remain unresolved.

TDP-43 aggregation in neurodegeneration: are stress granules the key? Publication Type: Journal Article. Authors: Dewey 

The HTRF signal was recorded after an overnight incubation. As expected, the overexpression of WT or mutated TDP-43 alone increase the aggregated ratio compared to non-transfected cells.

Aggregated TDP-43 sequesters specific microRNAs (miRNAs) and proteins, leading to increased levels of some proteins while functionally depleting others. Many of those functionally

TDP-43 aggregation inhibitors for the treatment of ALS. Award Information. Agency: Department of field This proposal provides an innovative new therapeutic approach to the disease that is based on reversing the aggregation of TDP which is a protein that is both genetically linked to familial ALS and is the predominant protein species

The strong role of TPD-43 in the pathophysiology of ALS points to TDP-43 as a cogent pharmacological target for disease modification. Aquinnah Pharmaceuticals has licensed 10 lead compounds that inhibit TDP-43 and SG aggregation that were identified in a high throughput screen performed in the laboratory of Dr. Benjamin Wolozin (Boston

2018. 4. 13. · Phosphorylated TDP-43 (pTDP-43) aggregates in the axial skeletal muscle of patients with sporadic and familial amyotrophic lateral sclerosis Acta Neuropathol Commun.

2019. 3. 8. · TAR DNA-binding protein 43 (TDP-43) is a nucleic acid–binding protein, and its aggregation represents the defining pathology in amyotrophic lateral sclerosis (ALS) and related proteinopathies. Recent studies implicate cytoplasmic stress granules (SGs) as hubs that may facilitate TDP-43 aggregation. Here, using cellular fractionation, biochemical analyses, and

Aggregated TDP-43 sequesters specific microRNAs (miRNAs) and proteins, leading to increased levels of some proteins while functionally depleting others. Many of those functionally perturbed gene

The substitution of TDP-43 amino acids responsible for RNA binding enhanced aggregate formation, indicating that RNA binding has a negative effect on the phase 

TDP-43 aggregates induce the mislocalization and aggregation of nucleoporins and transport factors. TDP-43-induced impairment of the nuclear

Our results show that differential expression of proteins in TDP-12xQ/N-F4L cells correlated with proteomic results of TDP-43 knockdown in SH-SY5Y, revealing a common set of proteins whose expression is influenced via TDP-43 aggregation or

TAR DNA-binding protein 43 (TDP-43) is a nucleic acid-binding protein, and its aggregation represents the defining pathology in amyotrophic lateral sclerosis (ALS) and related proteinopathies.
