Scavenger receptors in human airway epithelial cells: role in response to double-stranded RNA.

PLoS ONE, 2012
Scavenger receptors and Toll-like receptors (TLRs) cooperate in response to danger signals to adjust the host immune response. The TLR3 agonist double stranded (ds)RNA is an efficient activator of innate signalling in bronchial epithelial cells.

Protective or deleterious role of scavenger receptors SR-A and CD36 on host resistance to Staphylococcus aureus depends on the site of infection. [PDF]

PLoS ONE, 2014
Staphylococcus aureus is a major human opportunistic pathogen responsible for a broad spectrum of infections ranging from benign skin infection to more severe life threatening disorders (e.g.

Structures and high and low affinity ligand binding properties of murine type I and type II macrophage scavenger receptors

Journal of Lipid Research, 1993
Macrophage scavenger receptors have been implicated in various macrophage-associated processes, including atherosclerosis and clearance of bacterial endotoxin. They bind to a wide variety of polyanionic ligands and display complex binding characteristics.

Defective expression of scavenger receptors in celiac disease mucosa. [PDF]

PLoS ONE, 2014
Celiac disease (CD) is a gluten sensitive enteropathy characterized by a marked infiltration of the mucosa with immune cells, over-production of inflammatory cytokines and epithelial cell damage.

Factors regulating the activities of the low density lipoprotein receptor and the scavenger receptor on human monocyte-macrophages.

Journal of Lipid Research, 1981
Improved techniques of cell isolation resulted in 90 to 100 million monocytes from a single donor. Addition of low density lipoprotein (LDL) to to cultures of these cells resulted in the down regulation of LDL receptor activity.

Hydroxychloroquine Effects on THP-1 Macrophage Cholesterol Handling: Cell Culture Studies Corresponding to the TARGET Cardiovascular Trial

Medicina, 2022
Background and Objectives: Cardiovascular (CV) risk is elevated in rheumatoid arthritis (RA). RA patient plasma causes pro-atherogenic derangements in cholesterol transport leading to macrophage foam cell formation (FCF).

Innate scavenger receptor-A regulates adaptive T helper cell responses to pathogen infection

Nature Communications, 2017
Scavenger receptors can function as pattern recognition receptors to sense infection. Here the authors show that, in response to worm and bacterial infection, scavenger receptor class A prevents nuclear localization of IRF5 and thereby drives M2 ...

3582 Scavenger Receptor Expression is Differentially Affected by DNAzyme-Gold Nanoparticle Conjugates

Journal of Clinical and Translational Science, 2019
OBJECTIVES/SPECIFIC AIMS: Scavenger receptor (SR) surface proteins are highly conserved motifs and are implicated in the uptake of nanotherapies. Gold nanoparticles functionalized with DNAzymes (DzNP) represent a promising novel nanotherapy for lung ...

HSL-knockout mouse testis exhibits class B scavenger receptor upregulation and disrupted lipid raft microdomains[S]

Journal of Lipid Research, 2012
There is a tight relationship between fertility and changes in cholesterol metabolism during spermatogenesis. In the testis, class B scavenger receptors (SR-B) SR-BI, SR-BII, and LIMP II mediate the selective uptake of cholesterol esters from HDL, which ...

Physiological and pathogenic role of scavenger receptors in humans

Медицинская иммунология, 2020
The scavenger receptors (SRs)) include > 30 different molecules structurally classified into 11 classes (A to L). They are expressed mostly on stromal macrophages, and their expression may be augmented in direct dependence with concentrations of their
