[摘要]Sphingosine 1-phosphate receptor 1 (S1P(1)) is critical for lymphocyte recirculation and is a clinical target for treatment of multiple sclerosis. By generating a short-duration S1P(1) agonist and mice in which fluorescently tagged S1P(1) replaces wild-type receptor, we elucidate physiological and agonist-perturbed changes in expression of S1P(1) at a subcellular level in vivo. We demonstrate differential downregulation of S1P(1) on lymphocytes and endothelia after agonist treatment.
