A potential biomarker of cognitive impairment: The olfactory dysfunction and its genes expression

Annals of Clinical and Translational Neurology, Volume 9, Issue 12, Page 1884-1897, December 2022., 2022
Abstract Objective Accumulation evidence has reported that olfactory impairment may be an essential clinical marker and predictor of mild cognitive impairment or Alzheimer's disease. Method Participants were enrolled in the population‐based, prospective study in Fuxin county, Liaoning province, China between 2019 and 2021.

Hepatic Remnant Lipoprotein Clearance by Heparan Sulfate Proteoglycans and Low-Density Lipoprotein Receptors Depend on Dietary Conditions in Mice

Arteriosclerosis, Thrombosis and Vascular Biology, 2013
Objective—Chylomicron and very low-density lipoprotein remnants are cleared from the circulation in the liver by heparan sulfate proteoglycan (HSPG) receptors (syndecan-1), the low-density lipoprotein receptor (LDLR), and LDLR-related protein-1 (LRP1 ...

Scavenger Receptors Class A-I/II and CD36 Are the Principal Receptors Responsible for the Uptake of Modified Low Density Lipoprotein Leading to Lipid Loading in Macrophages*

Journal of Biological Chemistry, 2002
Modification of low density lipoprotein (LDL) can result in the avid uptake of these lipoproteins via a family of macrophage transmembrane proteins referred to as scavenger receptors (SRs).

Drosophila Lipophorin Receptors Recruit the Lipoprotein LTP to the Plasma Membrane to Mediate Lipid Uptake. [PDF]

PLoS Genetics, 2015
Lipophorin, the main Drosophila lipoprotein, circulates in the hemolymph transporting lipids between organs following routes that must adapt to changing physiological requirements.

High expression of antioxidant proteins in dendritic cells: possible implications in atherosclerosis [PDF]

Mol Cell Proteomics 5 (04/2006) 726-36, 2006
Dendritic cells (DCs) display the unique ability to activate naive T cells and to initiate primary T cell responses revealed in DC-T cell alloreactions. DCs frequently operate under stress conditions. Oxidative stress enhances the production of inflammatory cytokines by DCs.

Peroxisome Proliferator Activated Receptors and Lipoprotein Metabolism

PPAR Research, 2008
Plasma lipoproteins are responsible for carrying triglycerides and cholesterol in the blood and ensuring their delivery to target organs. Regulation of lipoprotein metabolism takes place at numerous levels including via changes in gene transcription.

Role of lipoprotein apheresis in the management of familial hypercholesterolemia

Global Journal of Transfusion Medicine, 2021
Familial Hypercholesterolemia (FH) is an autosomal dominant disorder due to a congenital absence of low-density lipoprotein receptor (LDL-R) that transports cholesterol-carrying lipoprotein particles into cells.

Direct imaging of lateral movements of AMPA receptors inside synapses [PDF]

EMBO J 22, 18 (15/09/2003) 4656-65, 2007
Trafficking of AMPA receptors in and out of synapses is crucial for synaptic plasticity. Previous studies have focused on the role of endo/exocytosis processes or that of lateral diffusion of extra-synaptic receptors. We have now directly imaged AMPAR movements inside and outside synapses of live neurons using single-molecule fluorescence microscopy ...

Revising Berg-Purcell for finite receptor kinetics [PDF]

, 2021
From nutrient uptake, to chemoreception, to synaptic transmission, many systems in cell biology depend on molecules diffusing and binding to membrane receptors. Mathematical analysis of such systems often neglects the fact that receptors process molecules at finite kinetic rates.

Enhanced macrophage degradation of low density lipoprotein previously incubated with cultured endothelial cells: recognition by receptors for acetylated low density lipoproteins.

Proceedings of the National Academy of Sciences of the United States of America, 1981
Human low density lipoprotein (LDL) was incubated with an established line of rabbit aortic endothelial cells. Density gradient fractionation showed a time-, concentration-, and temperature-dependent increase in the average density of the LDL (from about
