…..are secreted by cells infected with virus, alerting neighboring cells and protecting them from becoming infected
Interferons
When a cell gets infected with a virus, it is able to produce and secrete a group of proteins called interferons. Interferons are part of the body’s natural defense mechanism against viral infection. They work by alerting nearby cells and the immune system of the presence of a viral infection. This helps to initiate an antiviral response to protect the neighboring cells from becoming infected as well.
Interferons signal to neighboring cells to activate specific antiviral genes, which produce proteins that prevent viruses from reproducing and spreading. Interferons also increase the activity of immune cells such as T cells and natural killer cells, which can identify and destroy infected cells.
Furthermore, interferons can also help to activate immune responses that improve the overall immune defense against a wide range of viruses. For example, interferons can stimulate the development of antibodies and help prime the immune system to recognize and respond more effectively to viral infections.
In summary, interferons are an essential part of the body’s defense against viral infections. They help to alert neighboring cells of the presence of a viral infection, activate antiviral genes, stimulate immune cell activity, and promote overall immune defense.
