The present invention relates to a method for in vitro prognosis, diagnosis and/or monitoring of an inflammatory disease of the central nervous system in a subject, said method comprising detecting, in a sample of cells of the immune system from the subject, the presence of a Collapsin Response Mediator Protein 2 (CRMP2) which is phosphorylated on tyrosine 479 (Y479), and optionally further phosphorylated on serine 465 (S465), wherein the detection of the presence of Y479-phosphorylated CRMP2, which is optionally further phosphorylated on serine 465, is indicative of an inflammatory disease of the central nervous system.
