[From glioblastoma to COVID-19 – role of oxysterols in the human organism]
This review examines oxysterols as biologically active cholesterol derivatives that regulate metabolism and immunity, noting their elevated levels in pathological states including endometriosis.

This review article examines the biological roles of oxysterols, which are oxidized derivatives of cholesterol that serve as intermediates in the synthesis of vitamin D, bile acids, and steroid hormones. The authors discuss how these molecules exhibit pleiotropic effects by interacting with cellular receptors to regulate cholesterol metabolism and influence various cell types, often producing opposing physiological outcomes compared to unmodified cholesterol. Key findings highlight the ability of oxysterols to cross the blood-brain barrier, thereby affecting the nervous system, while also modulating immune responses through the activation or inhibition of immune cells during viral and inflammatory conditions. The paper notes that elevated tissue levels of oxysterols are frequently associated with pathological states including diabetes, atherosclerosis, dementia, and cancer. Relevance to endometriosis: listed as one condition where elevated oxysterol levels are observed, though the paper's main focus is on general biochemistry and other diseases like glioblastoma and COVID-19.
