What is the function of pegylated interferon?

Interferon is a broad-spectrum antiviral agent, which does not directly kill or inhibit the virus, mainly through the role of cell surface receptors, making cells produce antiviral proteins, thus inhibiting the replication of hepatitis B virus.

Pegylated interferon is a long-acting interferon formed by the combination of recombinant human interferon α2b (hereinafter referred to as common interferon) and polyethylene glycol (40kD Y type).

Interferon can bind to the specific α -interferon receptor on the cell surface, trigger the complex signal transduction pathway in the cell and activate gene transcription, regulate a variety of biological effects, including inhibiting virus replication and cell proliferation in infected cells, and have immunomodulatory effects. This product has antiviral and antiproliferative activities of non-PEG-bound α -interferon (common interferon) in vitro.

Extended data:

Interferon is highly species-specific, so animal interferon is ineffective for humans. Interferon has anti-virus, cell proliferation inhibition, immunomodulation and anti-tumor effects.

It is mainly used to treat advanced hairy cell leukemia, renal cancer, melanoma, Kaposi's sarcoma, chronic myeloid leukemia and moderate and low grade malignant non-Hodgkin's lymphoma. Others have been used for osteosarcoma, breast cancer, multiple myeloma, head and neck cancer and bladder cancer. It is also suitable for acute and chronic viral hepatitis C and chronic active hepatitis B.

Adverse reactions are mainly flu-like symptoms such as fever, fatigue, myalgia and headache. Followed by mild myelosuppression. Generally, it has no effect on liver and kidney function, and a few have elevated transaminase and serum creatinine.
