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).

The FUS and TDP-43 mutations listed in Table 1 cause mislocalisation of FUS and TPD-43 from the nucleus causing loss-of-'nuclear'-functions. The cytoplasmic accumulation of these proteins causes toxic-gain-of-function in association with cellular stress. These phenotypes are collectively referred to as proteinopathy.

Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease involving the formation of cytoplasmic aggregates by proteins including TDP-43 and SOD1, in affected cells in the central nervous system (CNS). Pathology spreads from an initial site of onset to contiguous anatomical regions.

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

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.

TDP-43 is a nuclear protein, and cytoplasmic aggregation of TDP-43 is a pathological marker of ALS. 24 We analyzed the subcellular distribution of TDP-43 in UBQLN2-transfected cells with or without

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.
