Development Of A Hek293 Cell Line To Show Inhibition Of Tau Aggregation, Justin Ray Shady
Electronic Theses and Dissertations
Intracellular deposition of aggregated tau is the hallmark of several different tauopathies, the most widespread of these being Alzheimer's disease. Tau is a highly soluble, intrinsically disordered, microtubule associated protein. Tau's native function is to stabilize microtubule formation in the axons of neurons. Post translational modification such as hyperphosphorylation as well as several familial mutations allow tau to nucleate and form fibrils. These fibrils can recruit healthy monomers onto their ends in a fashion described as template-assisted growth. Tau has 6 isoforms that vary by the inclusion or exclusion of two N-terminal repeats and the inclusion or exclusion of the …

Trans-activation response (TAR) DNA-binding protein 43 (TDP-43) is a natively dimeric 414-residue protein that is encoded by the human TARDBP gene that has important implications in the pathogenesis of the neurodegenerative disorders ALS, FTD, and CTE. TDP-43 has been found hyperphosphorylated and ubiquitinated in the aggregates of the affected neurons of these diseases. The discovery of the presence of TDP-43 positive inclusions in brain matter of patients with CTE has made repetitive brain injury a possible environmental stimulus for aggregation in TDP-43 proteinopathies. We expand upon the hypothesis that TDP-43 readily aggregates under agitation conditions and that the addition of …
