7α,25-Dihydroxycholesterol 是一种孤儿 GPCR 受体EBI2 (GPR183)的内源性配体和有效选择性激动剂。它对激活 EBI2 有很强的作用 (EC50=140 pM;Kd=450 pM)。它能够作为一种趋化因子，指导 B 细胞、T 细胞和树突状细胞的迁移。

7α, 25-dihydroxycholesterol (7α,25-OHC) is a potent and selective agonist and endogenous ligand of the orphan GPCR receptor EBI2 (GPR183). 7α, 25-dihydroxycholesterol can serve as a chemokine directing migration of B cells, T cells and dendritic cells[1][2], and it is highly potent at activating EBI2 (EC50=140 pM; Kd=450 pM).

7α, 25-dihydroxycholesterol (7α,25-OHC) stimulates the migration of EBI2-expressing mouse B and T cells with half-maximum effective concentration values around 500 pM in vitro. However, it had no effect on EBI2-deficient cells[1].

In vivo, EBI2-deficient B cells or normal B cells desensitized by 7α,25-Dihydroxycholesterol (1 μM; 1.5 hours) pre-treatment shows reduced homing to follicular areas of the spleen[1].
