Intrathecal increase of sphingosine 1-phosphate at early stage multiple sclerosis.

| Abstract |
Sphingosine 1-phosphate (S1P) is a pleiotropic mediator that is critically involved in the development of an inflammatory response in various pathological conditions. We hypothesize that during the course of multiple sclerosis (MS) development, chronic inflammation will result in the alteration of S1P levels in blood and cerebrospinal fluid (CSF). We evaluated S1P concentrations in blood and CSF obtained from 66 subjects, including 40 patients diagnosed with MS and 26 subjects of a control group that included patients diagnosed with idiopathic cephalgia and idiopathic (Bell's) facial nerve palsy. HPLC techniques were used to determine S1P levels. We found that S1P concentrations in blood of the MS subject group (361.7+/-150.7 nM) did not differ from those of the control group (371.9+/-142.5 nM). However, S1P concentrations in CSF of the MS group were significantly higher (p<0.01) compared to the control group (2.2+/-2.7 versus 0.69+/-1.1 nM). The increase of S1P concentration in CSF of MS subjects suggests that this bioactive lipid is involved in chronic inflammation associated with MS and it may be useful to study S1P in a number of neurodegenerative diseases to provide better understanding of the mechanisms governing their development.
