Blood lymphocyte numbers, essential for the development of
efficient immune responses, are maintained by recirculation throughsecondary lymphoid organs. We show that lymphocyte traffickingis
altered by the lysophospholipid sphingosine-1-phosphate (S1P)and
by a phosphoryl metabolite of the immunosuppressive agentFTY720. Both
species were high-affinity agonists of at least fourof the five S1P
receptors. These agonists produce lymphopeniain blood and thoracic
duct lymph by sequestration of lymphocytesin lymph nodes, but not
spleen. S1P receptor agonists inducedemptying of lymphoid sinuses by
retention of lymphocytes on theabluminal side of sinus-lining
endothelium and inhibition of egressinto lymph. Inhibition of
lymphocyte recirculation by activationof S1P receptors may result in
therapeutically useful immunosuppression.
