Quantitative analysis of transthyretin, tau and amyloid-beta in patients with dementia


Gloeckner, S F; Meyne, F; Wagner, F; Heinemann, U; Krasnianski, A; Meissner, B; Zerr, I (2008). Quantitative analysis of transthyretin, tau and amyloid-beta in patients with dementia. Journal of Alzheimer's Disease : JAD, 14(1):17-25.

Abstract

We carried out a quantitative analysis of transthyretin (TTR), total tau protein and amyloid-beta (Abeta) peptide (1-40 and 1-42) in the lumbar cerebrospinal fluid of 106 patients with different forms of dementia including Alzheimer's disease (AD), Creutzfeldt-Jakob-disease (CJD), dementia with Lewy bodies (DLB), frontotemporal dementia (FTD) and normal pressure hydrocephalus (NPH) in comparison to healthy controls. Our study revealed that Abeta_{1-42} levels were decreased in all patients irrespective of dementia type. Tau protein levels were abnormal in all degenerative dementia except of NPH. Tau levels did not allow differential diagnosis of dementia type except for CJD, where we observed extremely high CSF levels. In other dementia types, levels were elevated in a similar range. Transthyretin levels were selectively decreased in AD and NPH, thus revealing the potential of this protein to be used as additional biomarker in the neurochemical differential diagnosis of AD. A significant negative correlation of TTR CSF levels and disease severity in AD was observed.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
