Sphingosine kinase 2 deficient mice exhibit reduced experimental autoimmune encephalomyelitis: Resistance to FTY720 but not ST-968 treatments

In summary, these data demonstrated that deletion of SK-2 exerts a protective effect on the pathogenesis of EAE in C57BL/6 mice and that SK-2 is essential for the protective effect of FTY720 but not of ST-968. Thus, ST-968 is a promising novel immunomodulatory compound that may be a valuable alternative to FTY720 under conditions where SK-2 activity is limited.
