产品说明

一般描述

7α,25-dihydroxycholesterol (7α,25-OHC) is synthesized by the hydroxylation of cholesterol by the action of enzyme cholesterol 25-hydroxylase (CH25H) and cytochrome P450, family 7, subfamily b, polypeptide 1 (CYP7B1). The catabolic breakdown of 7α,25-OHC to bile acid precursors is catalyzed by the enzymes hydroxy-Δ-5-steroid dehydrogenase, 3β- and steroid Δ-isomerase 7 (HSD3B7).

应用

7α,25-dihydroxycholesterol has been used:

as a G-protein-coupled receptor 183 ( GPR183) ligand in chemotaxis assay and intracellular cytokine staining method and in fluorescence-activated cell sorting (FACS) analysis of natural killer cells
in oxysterol based calcium mobilization assay in Chinese hamster ovary (CHO) cells
in competitive radioligand binding assay of Epstein-Barr virus-induced gene 2 (EBI2) expressing COS-7 cells

生化/生理作用

7α,25-dihydroxycholesterol (7α,25-OHC) serves as an endogenous ligand for G-protein-coupled receptor 183 (GPR183) or Epstein-Barr virus-induced gene 2 (EBI2). It plays a key role in the migration of type 3 innate lymphoid cells (ILC3) in the small intestine and colon. 7α,25-OHC mediates immune cell migration functionality by their chemoattractant property. Inhibition of 7α,25-OHC synthesis leads to impairment in the migration of B cells.
