Sphingosine 1-phosphate receptor modulation attenuate mechanical allodynia in mouse model of chronic complex regional pain syndrome by suppressing pathogenic astrocyte activation.


FTY720 ((2-amino-2-)2-[4-octylphenyl]ethyl)-1,3-propanediol) is an Food and Drug Administration (FDA)-approved immunomodulatory drug for treating multiple sclerosis. It inhibits lymphocyte egression from lymphoid tissues by downregulating sphingosine-1 phosphate receptor (S1PR). To date, there has been no study on the effects of FTY720 on the chronic stage of the complex regional pain syndrome (CRPS) rodent model, despite its antiallodynic effect in previous studies. Thus, the aim of this study is to investigate the effect of FTY720 in a chronic stage of the CRPS mouse model.
