Characterization of Interferon Beta -1b-Induced Tolerizing Effect in Dendritic Cells
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.

- 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 ]
- 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 ]

no drug was given under study. patients already taking IFNbeta-1b were enrolled for blood draw only.
no drug was given under study arm. only blood draw on patients already on IFNbeta-1b.
