When a cell is infected with virus it sends out an interferon to warn other cells around it to stop transcription and translation and to produce antiviral proteins
Interferons help other cells resist the infection of viruses. They prevent the synthesis of a virus's proteins in infected cells and help block the virus from reproducing (replicating itself). This slows down the process of the infection and gives the immune system time to respond to the virus.
Interferons affect the immune system in a number of ways. For example, interferon beta can enhance the activity of lymphocyte cells while simultaneously inhibiting other immune cells from becoming stimulated
A protein released be cells infected with viruses.
Interferon binds to neighboring cells and stimulates these cells to produce antirival proteins which can prevent viral replication in these cells

substances produced to help body cells resist viruses
viruses and tumor cells
Lysozymes
Non specific defense mechanisms are more effective because they work against all bacteria and viruses. Examples are skin or tears. Specific defense mechanisms like antibodies work against one type of bacteria or virus. They're needed if a pathogen gets past the nonspecific defense mechanisms.
So viruses or diseases can not infect your body and kill you.
Interferon is a fluid protein found in everyone's bloodstream. It is made by the body to protect body cells from being invaded by viruses. Interferon is also used as an injection into a person that is deathly sick from a virus attack of some kind.
viruses and tumor cells
Yes
Interferons are hormonelike peprides that lymphocytes and fibrolasts produce in response to viruses or tumor cells.
Interferons
interferons
yes.It is true
protects cells that have not yet been infected by viruses
Lysozymes
Possible a defense against viruses. Some viruses have proteases in their reproductive cycle.
The multicellular organisms can use the lysosomes as a defense against viruses like AIDS by killing the viruses and bacteria that causes the opportunistic infections.
interferons
They inactivate viruses.
