Mode of action of BETAFERON in MS


Interferons belong to the family of naturally occurring proteins known as cytokines [1]. BETAFERON is a type I interferon and has shown antiviral and immunoregulatory activities in preclinical studies [1-3]. In MS, BETAFERON modulates the immune system at many levels [2,3]. Gene expression studies found that long-term treatment with BETAFERON corrected MS induced gene dysregulations and activated immunoregulatory and neuroprotective genes [4].

Below is a simplified illustration of the immunopathogenesis of MS [3,5-7] and an overview of the pleiotropic mechanism of action of interferon beta seen in MS [2,3]:


(The mechanisms by which BETAFERON exerts its actions in MS are still not fully understood [1].)
