1 In vitro, 7alpha,25-OHC stimulated the migration of EBI2-expressing mouse B and T cells with half-maximum effective concentration values around 500 pM, but had no effect on EBI2-deficient cells. 25-hydroxycholesterol G protein-coupled receptor 183 Mus musculus
2 In vivo, EBI2-deficient B cells or normal B cells desensitized by 7alpha,25-OHC pre-treatment showed reduced homing to follicular areas of the spleen. 25-hydroxycholesterol G protein-coupled receptor 183 Mus musculus
3 Blocking the synthesis of 7alpha,25-OHC in vivo with clotrimazole, a CYP7B1 inhibitor, reduced the content of 7alpha,25-OHC in the mouse spleen and promoted the migration of adoptively transferred pre-activated B cells to the T/B boundary (the boundary between the T-zone and B-zone in the spleen follicle), mimicking the phenotype of pre-activated B cells from EBI2-deficient mice. 25-hydroxycholesterol G protein-coupled receptor 183 Mus musculus
