Mechanism of action

Interferon α1b is a recombinant human interferon that engages type I interferon receptors (IFNAR1/IFNAR2) on cell surfaces, triggering JAK-STAT signaling pathways that upregulate antiviral genes, enhance natural killer cell activity, and promote Th1-mediated immune responses. When delivered via inhalation, it provides local immune activation in the respiratory tract, making it particularly suited for viral respiratory infections.
