Research activities: One of our major projects in the lab is to define the impact of the G-protein coupled receptor Epstein-Barr virus-induced gene 2 (EBI2 aka GPR183) in inflammation and its implications for the human immune system especially in psoriasis and MS. The major ligand of EBI2 is the 7α,25-dihydroxycholesterol (7α,25-OHC) which is generated by sequential hydroxylation of cholesterol via the enzymes cholesterol 25-hydroxylase (CH25H) and 25-hydroxycholesterol 7-alpha-hydroxylase (CYP7B1). We found that EBI2 confers an advantage to encephalitogenic T cells in migration into the inflamed brain in a mouse model for multiple sclerosis. We now want to focus on the role of EBI2 and of the ligand generating enzymes in T cell migration in different models of skin inflammation.
