2022. 9. 9. · A growing wave of evidence has placed the concept of protein homeostasis at the center of the pathogenesis of amyotrophic lateral sclerosis (ALS). This is due primarily to the presence of pathological transactive response DNA-binding protein (TDP-43), fused in sarcoma (FUS) or superoxide dismutase-1 (SOD1) inclusions within motor neurons of ALS postmortem

Aggregates of the TAR DNA binding protein 43 (TDP-43), are hallmark features of the neurodegenerative diseases Amyotrophic Lateral Sclerosis (ALS) and frontotemporal dementia (FTD), with overlapping clinical, genetic and pathological features.

TAR DNA-binding protein 43 (TDP-43) is a causative factor of amyotrophic lateral sclerosis (ALS). Cytoplasmic TDP-43 aggregates in neurons 

TDP-43 (encoded by TARDBP) is a predominantly nuclear DNA- and RNA-binding protein first discovered to bind to the trans-active response element in the human immunodeficiency virus (HIV)-1 sequence (Ou et al., 1995).TDP-43 was subsequently found to be the major constituent of pathogenic aggregates in amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD) neuropathology (Arai et

A hyper- phosphorylated, ubiquitinated and cleaved form of TDP-43—known as pathologic TDP43—is the major disease protein in ubiquitin -positive, tau-, and alpha-synuclein -negative frontotemporal dementia (FTLD-TDP, previously referred to as FTLD-U [37]) and in amyotrophic lateral sclerosis (ALS).

2022. 9. 13. · TDP-43 proteinopathy is the major pathology in amyotrophic lateral sclerosis (ALS) and tau-negative frontotemporal dementia (FTD). Mounting evidence implicates loss of normal TDP-43 RNA-processing function as a key pathomechanism. However, the RNA targets of TDP-43 differ by report, and have never been formally collated or compared between models and

In up to 97% of ALS cases and ~50% of FTLD cases, the primary pathological protein observed in affected tissues is TDP-43, which is hyperphosphorylated, ubiquitinated and cleaved. The TDP-43 is observed in aggregates that are abnormally located in the cytoplasm.

However, recent studies show that almost all cases of ALS, as well as tau-negative frontotemporal dementia (FTD), share a common neuropathology 

2022. 4. 1. · Since the cytosolic inclusion of TDP-43 is seen in almost all cases of ALS, regardless of the TDP-43 genotype, TDP-43 is thought to be a central hub molecule, linking both familial and sporadic ALS. Therefore, elucidation of the molecular mechanisms underlying TDP-43-related neurotoxicity would contribute to understanding the pathophysiology of this merciless disease.
