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

Oxysterol signaling in the central nervous system: cellular mechanisms and implications for neurodegeneration [PDF]
Frontiers in Molecular NeuroscienceOxysterols, oxidized derivatives of cholesterol, are key modulators of central nervous system (CNS) function. Acting as both signaling molecules and cytotoxic mediators, oxysterols can influence glial activity, neuroinflammation and myelination.

Oxysterols in the Immune Response to Bacterial and Viral Infections
Cells, 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]
PLoS 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 ...
