TDP-43 and frontotemporal dementia

TDP-43 and frontotemporal dementia TAR DNA-binding protein of about 43 kDa (TDP-43) is the main ubiquitinated peptide in tau-negative frontotemporal lobar degeneration (FTLD). TDP-43 is typically a nuclear protein, and its aggregation and cytoplasmic translocation are thought to represent major steps in the pathogenesis of FTLD due to TDP-43 proteinopathy (FTLD-TDP). Certain clinical syndromes of frontotemporal dementia are preferentially associated with pathologic findings of FTLD-TDP, and TDP-43 pathology represents the connection between FTLD-TDP and amyotrophic lateral sclerosis. Recent advances in clinical, genetic, and pathologic studies of FTLD-TDP and amyotrophic lateral sclerosis have shed light on the potentially pathogenic role of TDP-43 and identified TDP-43 itself as a candidate biomarker for antemortem diagnosis of FTLD-TDP. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Current Neurology and Neuroscience Reports Springer Journals

Abstract

TAR DNA-binding protein of about 43 kDa (TDP-43) is the main ubiquitinated peptide in tau-negative frontotemporal lobar degeneration (FTLD). TDP-43 is typically a nuclear protein, and its aggregation and cytoplasmic translocation are thought to represent major steps in the pathogenesis of FTLD due to TDP-43 proteinopathy (FTLD-TDP). Certain clinical syndromes of frontotemporal dementia are preferentially associated with pathologic findings of FTLD-TDP, and TDP-43 pathology represents the connection between FTLD-TDP and amyotrophic lateral sclerosis. Recent advances in clinical, genetic, and pathologic studies of FTLD-TDP and amyotrophic lateral sclerosis have shed light on the potentially pathogenic role of TDP-43 and identified TDP-43 itself as a candidate biomarker for antemortem diagnosis of FTLD-TDP.
