  Purpose

Determine the in-vivo mechanism of action of INF-B-1b as it's mechanisms of action are not completely understood. We propose that high dose exogenous recombinant IFN-B-1b induces tolerizing effect on DC-dependent T-cell differentiation in patients with MS by inducing the expression of SOCS3 in DCs.

Primary Outcome Measures:
  • Determine the effect of IFN-B-1b-induced SOCS3 upregulation in DCs' on their maturation and the capacity to present [ Time Frame: 2 years ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Characterize the effect of IFN-1b-induced SOCS3 expression in DCs on Th1/Th2 cell differentiation and T-cell cytokine transcription. [ Time Frame: 2 years ] [ Designated as safety issue: No ]
