Application

7α,25-Dihydroxycholesterol has been used as a ligand for G protein-coupled receptor 183 (Gpr183).

Biochem/physiol Actions

7α,25-Dihydroxycholesterol (7α,25-OHC) is a potent and selective endogenous ligand for the orphan GPCR receptor EBI2 (GPR183) with an EC50 value in the picomolar range. The newly discovered EBI2–oxysterol signalling pathway has been shown to have an important role in the adaptive immune response, including a role in driving immune cell migration. In vitro and in vivo studies showed that 7,25-OHC can serve as a chemokine directing migration of B cells, T cells and dendritic cells.
7α,25-Dihydroxycholesterol has an ability to block the early steps of T-cell activation.

Several oxysterols are powerful immunosuppressors. Among them 7,25-dihydroxycholesterol (7,25-OHC) seems to be particularly interesting. The effect of this synthetic sterol on murine lymphocytes, stimulated by Con A, or by allogeneic or TNP-modified syngeneic lymphocytes, was investigated. The results showed that

The metabolism of 25-hydroxycholesterol in different cell types was studied and the role of 7 alpha-hydroxylation for the effect of 25-hydroxycholesterol on the activity of HMG-CoA reductase was determined. Human diploid fibroblasts (HDF) and the human melanoma cell line SK-MEL-2

Oxygenated derivatives of cholesterol are potent immunosuppressors. It has been reported previously that 7,25-dihydroxycholesterol (7,25-OHC), synthesized in the URA31, strongly inhibits the early steps of T-cell activation. So far, the mechanisms underlying this type of effect have been mainly investigated

Recent findings extend the biologic activities of oxysterols as ligands for nuclear receptors to a role in morphogenesis during fetal development and to a role in the metabolism of photooxidation products of cholesterol in the retina. A 1000-fold increase of

New water soluble derivatives of oxysterols--the phosphodiesters of oxysterols and of nucleosides--have been synthesized. In vitro, these compounds share the biological properties of their parent oxysterols. Furthermore, they display anticancer activity when injected i.p. in mice bearing experimental tumors. The
