IFN-beta, Human (CHO)

IFN-beta is a secretory cytokine produced by cells under viral infection or nucleic acid stimulation. IFNβ binds to cell surface heterodimeric receptors (IFNAR1/IFNAR2), activates the JAK-STAT signaling pathway, and induces the expression of interferon-stimulated genes (ISGs) (such as PKR, 2'5'-OAS) . IFN-beta inhibits viral proliferation, regulates immune responses (such as inhibiting Th1 cell polarization, reducing pro-inflammatory cytokine secretion), inhibits the proliferation of vascular smooth muscle cells and tumor cells. IFN-beta has anti-atherosclerotic and vascular remodeling effects. IFN-beta Protein, Human (CHO) is a recombinant interferon-beta protein (CHO), expressed by CHO, without a tag.
