Impact of individual acute phase serum amyloid A isoforms on HDL metabolism in mice[S]

Journal of Lipid Research, 2016
The acute phase (AP) reactant serum amyloid A (SAA), an HDL apolipoprotein, exhibits pro-inflammatory activities, but its physiological function(s) are poorly understood.

Amyotrophic Lateral Sclerosis and Frontotemporal Dementia Have Distinct Prediagnostic Blood Biochemical Profiles

Annals of Neurology, EarlyView.
Objective Identifying modifiable factors influencing amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD) risk is important for prevention. Blood biomarkers, particularly cholesterol, have been associated with neurodegenerative risk, but findings in ALS are inconsistent, and data on FTD are limited.

Reduction in apolipoprotein-mediated removal of cellular lipids by immortalization of human fibroblasts and its reversion by cAMP: lack of effect with Tangier disease cells

Journal of Lipid Research, 1999
High density lipoprotein (HDL) phospholipids and apolipoproteins remove cellular lipids by two distinct mechanisms, but their relative contribution to reverse cholesterol transport is unknown.

When Does Alzheimer's Disease Start? Plasma Aβ42/40 Assays Show Steep Changes at Aβ‐PET Centiloid 15, Mean Age of 66 Years

Annals of Neurology, EarlyView.
Objective Sporadic late‐onset Alzheimer's disease (AD) is characterized by a long pre‐clinical phase where amyloid‐beta (Aβ) and tau begin to accumulate in the brain. The primary objective was to determine the age at which AD starts by finding the average population age when both positron emission tomography (PET) Aβ (Aβ‐PET) and plasma Aβ42/40 become ...

The ratio of low-density lipoprotein cholesterol to apolipoprotein-B as a marker of low-density lipoprotein particle size

Атеросклероз, 2018
The aim of this study was to determine the informative value and clinical significance of the ratio of low-density lipoprotein cholesterol to apolipoprotein-B (LDL-C/apoB) in the overall evaluation of blood lipid profile atherogenicity.

Apolipoprotein B48 RNA Editing in Chimeric Apolipoprotein EB mRNA

Journal of Biological Chemistry, 1989
Apolipoprotein (apo) B occurs in two forms, apoB100 (512 kDa) and apoB48 (240 kDa); both are derived from the same gene. A novel mechanism involving editing of the apoB mRNA causes the formation of apoB48; the first base of codon 2153 is changed from cytosine to uracil, converting a glutamine codon to a premature stop codon.

Chronological Diagnostic Algorithm Predicting Neuropathology in Parkinsonism

Annals of Neurology, EarlyView.
Objective Pre‐mortem diagnosis of parkinsonism is often challenging due to atypical presentations, overlapping syndromes, and co‐pathologies. This study aimed to develop a machine learning‐based algorithm predicting neuropathology in parkinsonism using chronological clinical presentations, which has previously been underexplored.

Omega-3 fatty acids, lipids, and apoE lipidation in Alzheimer's disease: a rationale for multi-nutrient dementia prevention

Journal of Lipid Research, 2017
In the last decade, it has become obvious that Alzheimer's disease (AD) is closely linked to changes in lipids or lipid metabolism. One of the main pathological hallmarks of AD is amyloid-β (Aβ) deposition.

Accumulation of apolipoproteins in the regenerating and remyelinating mammalian peripheral nerve. Identification of apolipoprotein D, apolipoprotein A-IV, apolipoprotein E, and apolipoprotein A-I.

Journal of Biological Chemistry, 1990
In this report, we have identified two apolipoproteins (apo), apoD and apoA-IV, that, together with the previously identified apoA-I and apoE, accumulate in the regenerating peripheral nerve. These four apolipoproteins were identified in regenerating rat sciatic nerves by their molecular weights, their isoelectric points, and their recognition by ...

Temporal Modeling of Amyloid and Tau Trajectories in Alzheimer's Disease Using PET and Plasma Biomarkers

Annals of Neurology, EarlyView.
Objective This study aimed to compare positron emission tomography (PET) and plasma‐based temporal modeling of amyloid and tau biomarkers in Alzheimer's disease. Methods Longitudinal amyloid PET (n = 1,097, mean age ± SD = 72.5 ± 7.38 year, 51.4% male), 18F‐flortaucipir tau‐PET (n = 230, 74.3 ± 7.18 year, 52.2% female), and Fujirebio Lumipulse plasma p‐
