Oxidized phospholipid damage signals as modulators of immunity [PDF]

Open Biology
Damage-associated molecular patterns (DAMPs) are self-derived molecules released during tissue damage that influence immune responses. Phospholipids, essential to cell membranes and lung surfactants, become oxidized under conditions of cellular stress ...

Simplified synthesis of oxidized phospholipids on alkyl-amide scaffold [PDF]

MethodsX
Oxidized phospholipids (OxPLs), containing oxidized fatty acids (oxylipins), play a significant role in various diseases. However, studying the structure-activity relationships of OxPLs and their signaling mechanisms is challenging due to the complexity ...

Oxidized phospholipids regulate amino acid metabolism through MTHFD2 to facilitate nucleotide release in endothelial cells

Nature Communications, 2018
During atherosclerosis, endothelial cells release purines in response to oxidized phospholipids. Here, Hitzel et al. show that oxidized phospholipids activate an MTHFD2-regulated gene network in endothelial cells which reprograms amino acid metabolism ...

Pain Control by Targeting Oxidized Phospholipids: Functions, Mechanisms, Perspectives [PDF]

Frontiers in Endocrinology, 2021
Within the lipidome oxidized phospholipids (OxPL) form a class of chemically highly reactive metabolites. OxPL are acutely produced in inflamed tissue and act as endogenous, proalgesic (pain-inducing) metabolites. They excite sensory, nociceptive neurons

Macrophage phenotype and bioenergetics are controlled by oxidized phospholipids identified in lean and obese adipose tissue

Proceedings of the National Academy of Sciences of the United States of America, 2018
Significance Adipose tissue macrophages (ATMs) maintain adipose tissue homeostasis. However, during obesity ATMs become inflammatory, resulting in impaired adipose tissue function. Oxidative stress increases during obesity, which is thought to contribute

Low Concentrations of Oxidized Phospholipids Increase Stress Tolerance of Endothelial Cells [PDF]

Antioxidants, 2022
Oxidized phospholipids (OxPLs) are generated by enzymatic or autooxidation of esterified polyunsaturated fatty acids (PUFAs) residues. OxPLs are present in circulation and atherosclerotic plaques where they are thought to induce predominantly ...

Associations between lipoprotein(a), oxidized phospholipids, and extracoronary vascular disease [PDF]

Journal of Lipid Research
The roles of lipoprotein(a) [Lp(a)] and related oxidized phospholipids (OxPLs) in the development and progression of coronary disease is known, but their influence on extracoronary vascular disease is not well-established.

Endogenous oxidized phospholipids reprogram cellular metabolism and boost hyperinflammation [PDF]

Nat Immunol, 2019
Pathogen-associated molecular patterns (PAMPs) have the capacity to couple inflammatory gene expression to changes in macrophage metabolism, both of which influence subsequent inflammatory activities. Similar to their microbial counterparts, several self-
