Apolipoprotein E in cerebrospinal fluid: relation to phenotype and plasma apolipoprotein E concentrations.
BACKGROUND Apolipoprotein (apo) E may be related to the development of Alzheimer disease, but data on apoE in cerebrospinal fluid (CSF) are limited. The aim of the present study was to measure apoE in CSF and relate its concentrations to apoE phenotype and CSF lipids. METHODS We adapted an assay for CSF apoE sensitivity using an ELISA. It allowed us to measure CSF apoE with sufficient reprodu...
متن کاملCerebrospinal Fluid Apolipoprotein E Levels in Delirium
BACKGROUND/AIMS Delirium and the apolipoprotein E ε4 allele are risk factors for late-onset Alzheimer disease (LOAD), but the connection is unclear. We looked for an association. METHODS Inpatients with delirium (n = 18) were compared with LOAD outpatients (n = 19), assaying blood and cerebrospinal fluid (CSF) using multiplex ELISA. RESULTS The patients with delirium had a higher Confusion ...
متن کاملThe effect of LCZ696 (sacubitril/valsartan) on amyloid‐β concentrations in cerebrospinal fluid in healthy subjects
AIMS LCZ696 (angiotensin receptor neprilysin inhibitor) is a novel drug developed for the treatment of heart failure with reduced ejection fraction. Neprilysin is one of multiple enzymes degrading amyloid-β (Aβ). Its inhibition may increase Aβ levels. The potential exists that treatment of LCZ696, through the inhibition of neprilysin by LBQ657 (an LCZ696 metabolite), may result in accumulation ...
متن کاملLongitudinal study of cerebrospinal fluid amyloid proteins and apolipoprotein E in patients with probable Alzheimer's disease.
Levels of soluble amyloid beta protein (sAbeta), amyloid beta precursor protein (APP) and apolipoprotein E (apoE) were examined in cerebrospinal fluid (CSF) obtained twice, at baseline and after 3-year follow-up, from 25 patients with probable Alzheimer's disease (AD). Levels of sAbeta and apoE from patients with the apoE4 allele decreased with time, whereas the levels were similar in patients ...
متن کاملPreoperative cerebrospinal fluid β-Amyloid/Tau ratio and postoperative delirium
OBJECTIVE The neuropathogenesis of postoperative delirium remains unknown. Low cerebrospinal fluid (CSF) βamyloid protein (Aβ) and high CSF Tau levels are associated with Alzheimer's disease. We therefore assessed whether lower preoperative CSF Aβ/Tau ratio was associated with higher incidence and greater severity of postoperative delirium. METHODS One hundred and fifty three participants (71...
