Age-related changes of plasma levels of oxysterols in schizophrenia (SCZ) patients, clinically high risk (CHR) individuals, and healthy controls (HC). (A,B) Absolute values of 24OHC at different ages; (C,D) Absolute values of 27OHC at different ages. (E,F) Ratio of 24OHC and 27OHC at different ages. Significant age-dependent decreases of 24OHC levels and 24OHC/27OHC values were found in the HCs. Opposite trend of 24OHC levels and 24OHC/27OHC values along with age were found between HCs and CHR individuals or SCZ patients, and the largest difference occurs before 25 years old. Plasma 27OHC levels showed significant age-dependent decrease in the SCZ group. Unlike 24OHC, the difference in 27OHC between patients and HCs became more and more significant with the increase of age.
