Interferon can treat herpes, interferon is a class of naturally occurring small protein molecules produced and secreted by cells in response to viral infection or a variety of synthetic and biogenic effects, it is divided into two broad categories, type I and type II, not every interferon has all the activity. Among them, recombinant interferon α-2a, α-2b and α-1b have broad-spectrum antiviral, antitumor and immunomodulatory functions, which can bind to cell surface receptors and induce cells to produce a variety of antiviral proteins, thus inhibiting viral replication in the cell, which can curb viral information and infections by regulating immune functions and enhancing specific cytotoxicity of macrophage lymphocytes to target cells, and can also Enhance the activity of natural killer cells, inhibit the growth of tumor cells, remove early tumor cells, etc. So recombinant interferon α-2a, α-1b, α-2b can treat herpes.
