tdp-43 aggregation

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 properties have been

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 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

Transactive response DNA binding protein 43 (TDP-43) is a DNA/RNA binding TDP-43 aggregation but rather to both loss and gain-of-function processes 

2013. 8. 9. · Background: TAR DNA-binding protein 43 (TDP-43) is a protein that is involved in the pathology of Amyotrophic Lateral Sclerosis (ALS) and Frontotemporal Lobar Degeneration

A Possible Path to Preventing TDP-43 Aggregation. TDP-43 is known to increase with age, and also forms aggregates observed in ALS and frontemporal dementia, among other conditions. The increased amount of TDP-43 alone, even without aggregates, appears to diminish the cellular housekeeping process of autophagy, with detrimental long term

2022. 4. 27. · TDP-43, a nuclear protein encoded by the TARDBP gene, is critical to cellular function through its role in transcriptional repression and exon skipping activation (Ratti and Buratti, ). Hallmark features of TDP-43 proteinopathies include cytoplasmic TDP-43 protein aggregations and TDP-43 nuclear depletion.

Moreover, TDP-43 is an aggregation-prone protein and, given the role of toxic protein aggregates in neurodegeneration, a toxic gain-of-function mechanism is another rational hypothesis. Importantly, ALS related mutations modulate the propensity of TDP-43 to aggregate in cell culture.

TDP-43 can form cytoplasmic aggregates that deleteriously affect neuronal health, including cellular toxicity, signaling cascade interference, and sequestration of additional TDP-43, thus rendering it inactive. Such aggregates are present in 97% and 50% of ALS and FTLD patients, respectively (de Boer et al., ; Jo et al., ).

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 

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