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).

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.

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.

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

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 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

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

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

Thus, unraveling the molecular mechanisms of the TDP-43 pathology seems central to the ALS therapeutics, hence, we comprehensively review the current

2014. 12. 9. · Amyotrophic lateral sclerosis These mechanisms could be a plausible molecular basis for this disease continuum and, This misfolded conformation then recruits native monomers of TDP-43 to induce pathological misfolding on to the native form in what is known as ‘templated conformational change’.

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.

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).
