The mechanism of action of IFNβ is complex, involving effects at multiple levels of cellular function. Purpose Interferon beta receptor 2 subunit (IFNAR2) can be produced as a transmembrane protein, but also as a soluble form (sIFNAR2) generated by alternative splicing or proteolytic cleavage, which has both agonist and antagonist activities for IFN-β. Gamma interferon, which is released at the start of an immune response, encourages inflammation in the tissue under attack. Neurology. It is approved for use after the first MS event.
