The molecular mechanisms for the interferon beta (IFNbeta) treatment of multiple sclerosis (MS) remain to be characterized.

Using cDNA microarray technology, we have compared the gene expression profile of T and non-T cells derived from relapsing-remitting MS before and after treatment with IFNbeta-1b.

IFNbeta treatment significantly altered expression of 21 genes out of 1263 at 3 and 6 months after treatment.

These genes included nine with IFN-responsive promoter elements.

Whereas there was no change in Th1 or Th2 marker genes, some of the changes were unexpected but coincided with the beneficial effect of IFNbeta in MS.
