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.
7α,25-Dihydroxycholesterol is a potent agonist of the orphan GPCR receptor EBI2 (GPR183); directs immune cell migration.
