TAR DNA binding protein 43 (TDP-43) is closely related to the pathogenesis of amyotrophic lateral sclerosis (ALS) and translocates to stress granules (SGs). The role of SGs as aggregation

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

2018. 11. 16. · 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. TDP-43 and Neurodegeneration: From Bench to Bedside summarizes new findings in TDP-43 pathobiology

Accumulations of aggregated proteins are a key feature of the pathology of all of the major neurodegenerative diseases. Amyotrophic lateral sclerosis (ALS) was brought into this fold quite recently with the discovery of TDP-43 (TAR DNA binding protein, 43 kDa) inclusions in nearly all ALS cases. In

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).

Amyotrophic lateral sclerosis (ALS) is a rapidly progressive neurodegenerative disorder involving loss of upper and lower motor neurons, with most cases ending in death within 3-5 years of onset. Several molecular and cellular pathways have been identified to cause ALS; however, treatments to stop or reverse disease progression are yet to be found. Riluzole, a neuroprotective agent offering

Using oligoclonal capture antibodies, all TDP-43 isoforms are extracted out of CSF. (A) First, a germanium crystal (grey) is chemically functionalized by using a self-synthesized silane (brown). (B) In a second step the antibody (light green) is covalently attached to the functionalized silane sensor surface (brown) of a germanium crystal (grey).

Previously, variants in Superoxide Dismutase 1 (SOD1) causing Amyotrophic Lateral Sclerosis (ALS) were found to destabilize and reduce net charge, suggesting a pathogenic aggregation mechanism. This paper reports analysis of compiled patient data and experimental and computed protein properties for variants of human SOD1, a major risk factor of

Introduction. Jean-Martin Charcot (1825-1893), in his comments of 1887, underestimated the complexity of the neurodegenerative disease he named "la sclérose amyotrophique": The diagnosis as well as the anatomy and physiology of the condition amyotrophic lateral sclerosis is one of the most completely understood conditions in the realm of clinical neurology.

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.

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.
