摘 要:During their life,T cells are constantly circulating throughout the ***-1-phosphate(S1P),a sphingolipid metabolite,triggers T cell egress from the thymus and secondary lymphoid organs(SLO)into the lymph and the *** phenomenon is dependent on the S1P gradient between lymphoid organs(including thymus and SLO)and the lymphatic and blood vessels,which exhibit low,intermediate and high S1P levels,respectively.T cells follow the S1P gradient via the engagement of the G-protein-coupled receptor S1P receptor 1(S1P1)expressed on T cells.1 S1P production is regulated by various sphingolipid-metabolizing *** sphingosine kinases 1 and 2(SKs),encoded by Sphk1 and Sphk2,phosphorylate the sphingosine(Sph)into ***,S1P can be dephosphorylated to Sph by S1P phosphatases 1 and 2,encoded by Sgpp1 and ***,S1P can be irreversibly degraded by the S1P Lyase(SPL),encoded by Sgpl1,into phosphoethanolamine and hexadecenal.
