Explanation:
Small proteins released from tissue cells infected with viruses, as well as from activated lymphocytes and macrophages, are called Interferons
<h3>What are Interferons ?</h3>
A collection of signalling proteins known as interferons are produced and released by host cells in response to the presence of certain viruses. Typically, a virus-infected cell will release interferons, boosting the antiviral defences of neighbouring cells.
- They are released by infected cells, where they trigger the innate immune system's production of cytokines as well as natural killer cell activity and antigen presentation.
- By establishing cytokine barriers, interferons shield uninfected cells from subsequent viral infections. Additionally, they prevent cellular division and control the organism's immune response.
