Scavenger Receptors and Atherosclerosis
Scavenger receptors were discovered as cell surface proteins capable of binding and internalization of modified lipoproteins. These receptors exhibit a broad ligand binding specificity including potential physiological and pathophysiological ligands other than modified lipoproteins.

Macrophage Scavenger Receptor Class A [PDF]
Abstract—In atherogenesis, elevated plasma levels of low density lipoprotein (LDL) lead to the chronic presence of LDL in the arterial wall. There, LDL is modified (eg, oxidized), and these modified lipoproteins activate endothelial cells, which attract circulating monocytes.

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

Lipoprotein receptor interactions are not required for monocyte oxidation of LDL.
Upon activation, human peripheral blood monocytes and U937 cells oxidized low density lipoprotein (LDL), converting it to a cytotoxin. The oxidized LDL loses its ability to interact specifically with the native LDL (apoB/E) receptor and becomes a ligand ...

Apoptotic cell recognition receptors and scavenger receptors [PDF]
SummaryPhosphatidylserine recognition receptors are a highly diverse set of receptors grouped by their ability to recognize the ‘eat‐me’ signal phosphatidylserine on apoptotic cells. Most of the phosphatidylserine recognition receptors dampen inflammation by inducing the production of anti‐inflammatory mediators during the phagocytosis of apoptotic ...

Activated scavenger receptor A promotes glial internalization of aβ. [PDF]
Beta-amyloid (Aβ) aggregates have a pivotal role in pathological processing of Alzheimer's disease (AD). The clearance of Aβ monomer or aggregates is a causal strategy for AD treatment.

Scavenger receptors clear the air [PDF]
Inhaled environmental oxidants, such as ozone and particulates, have been variably linked to epithelial injury, inflammation, and perturbations in lung development, growth, and function. Reactions between ozone and lung surface lipids likely account for exposure-related pathophysiologic sequelae. In this issue of the JCI, Dahl et al.

Scavenger Receptors in Atherosclerosis [PDF]
Atherosclerotic vascular disease arises as a consequence of the deposition and retention of serum lipoproteins in the artery wall. Macrophages in lesions have been shown to express ≥6 structurally different scavenger receptors for uptake of modified forms of low-density lipoproteins (LDLs) that promote the cellular accumulation of cholesterol.

Acute caffeine treatment protects the developing retina from ischemia‐induced cell death
Caffeine reduces cell death in the developing retina under ischemia (OGD). This effect does not involve BDNF upregulation or antioxidant pathways (NRF2/VEGF). Neuroprotection occurs mainly through adenosine A2A receptor antagonism, decreasing glutamate release and excitotoxicity, highlighting caffeine's potential as an acute neuroprotective agent in ...

Abruptly changing from aerobic to anaerobic conditions (sudden anaerobization) induced growth inhibition and a significant increase in intracellular labile ferrous iron in the aerotolerant anaerobe Amphibacillus xylanus. We found that free flavins mediate efficient electron transfer from NADH to ferric iron under anaerobic conditions, suggesting that ...
