Mechanism of action

PEGinterferon alfa-2a is a pegylated form of interferon alfa-2a that binds to interferon-alpha receptors on immune cells and hepatocytes, triggering JAK-STAT signaling and upregulation of interferon-stimulated genes. This leads to enhanced natural killer cell activity, increased MHC expression, and direct antiviral effects. The pegylation extends the drug's half-life, allowing for less frequent dosing compared to standard interferon alfa-2a.
