22(S)-hydroxy Cholesterol is a synthetic oxysterol and a modulator of the liver X receptor (LXR). [1] t prevents monocyte chemoattractant protein 1 (MCP-1) expression induced by the LXR agonist GW 3965 in primary hepatocytes and downregulates mRNA expression of the LXR target genes CD36, ACSL1, and SCD-1 in human myotubes. It decreases triacylglycerol and diacylglycerol synthesis from labeled palmitate and acetate, respectively, in human myoblasts by 50% when used at a concentration of 10 uM. 22(S)-hydroxy Cholesterol also reduces fatty acid synthase (FAS) reporter activity through an LXR response element in the promoter region in COS-1 cells transfected with RXRα and LXRα and decreases the expression of MCP-1 and CCR2 in a mouse model of chronic ethanol consumption.[1] [2] Dietary supplementation of 22(S)-hydroxy cholesterol (30 mg/kg per day) leads to less body weight gain and lower liver triacylglycerol levels in rats when fed either a regular chow or high-fat diet as well as prevents an increase in plasma triacylglycerol levels resulting from a high-fat diet.[3]

7β,27-dihydroxy Cholesterol is an oxysterol and agonist of retinoic acid receptor-related orphan receptor γ (RORγ) and RORγt. [1] It activates RORγ- or RORγt-dependent signaling with EC50 values of 691 and 1,045 nM, respectively, in reporter assays using HEK293T cells expressing the recombinant human receptors. 7β,27-dihydroxy Cholesterol is selective for RORγ and RORγt over a panel of eight additional nuclear receptors at 30 µM. It increases IL-17A production in Th17-polarized isolated human na ve CD4+ T cells when used at a concentration of 300 nM. 7β,27-dihydroxy Cholesterol (60 mg/kg) increases IL-17A production in isolated mouse γδ T cells stimulated with 12-myristate 13-acetate and ionomycin .
