Impact of Oxysterols on Cell Death, Proliferation, and Differentiation Induction: Current Status

open access: yesCells, 2021
Oxysterols are oxidized derivatives of cholesterol produced by enzymatic activity or non-enzymatic pathways (auto-oxidation). The oxidation processes lead to the synthesis of about 60 different oxysterols.

Effects of Oxysterols on Immune Cells and Related Diseases

open access: yesCells, 2022
Oxysterols are the products of cholesterol oxidation. They have a wide range of effects on several cells, organs, and systems in the body. Oxysterols also have an influence on the physiology of the immune system, from immune cell maturation and migration

Dietary oxysterols are incorporated in plasma triglyceriderich lipoproteins, increase their susceptibility to oxidation and increase aortic cholesterol concentration of rabbits

open access: yesJournal of Lipid Research, 1998
Early fatty streaks and advanced lesions are characterized by the deposition of cholesterol and cholesterol oxidation products (oxysterols). Oxysterols have been shown to be cytotoxic and pro-atherogenic compared to cholesterol and are found in ...

HSD3B1 is an oxysterol 3β-hydroxysteroid dehydrogenase in human placenta

open access: yesOpen Biology, 2023
Most biologically active oxysterols have a 3β-hydroxy-5-ene function in the ring system with an additional site of oxidation at C-7 or on the side-chain.

Oxysterols in the Immune Response to Bacterial and Viral Infections

open access: yesCells, 2022
Oxidized cholesterols, the so-called oxysterols, are widely known to regulate cholesterol homeostasis. However, more recently oxysterols have emerged as important lipid mediators in the response to both bacterial and viral infections.

Simultaneous determination of oxysterols, cholesterol and 25-hydroxy-vitamin D3 in human plasma by LC-UV-MS. [PDF]

open access: yesPLoS ONE, 2015
Oxysterols are promising biomarkers of neurodegenerative diseases that are linked with cholesterol and vitamin D metabolism. There is an unmet need for methods capable of sensitive, and simultaneous quantitation of multiple oxysterols, vitamin D and ...

Sulphatation does not appear to be a protective mechanism to prevent oxysterol accumulation in humans and mice. [PDF]

open access: yesPLoS ONE, 2013
24S- and 27-hydroxycholesterol (24OHC and 27OHC) are potent regulators of different biochemical systems in vitro and are the major circulating oxysterols.
