Question

what are interferon how do they help in developing resistance to infection​

Answer 1

Answer:

Interferons are a group of signaling proteins which are made and released by host cells in response to the presence of several viruses. In a typical scenario, a virus-infected cell will release interferons causing nearby cells to heighten their anti-viral defenses.

They belong to the large class of proteins known as cytokines, molecules used for communication between cells to trigger the protective defenses of the immune system that help eradicate pathogens. Interferons are named for their ability to "interfere" with viral replication by protecting cells from virus infections

Hope this much is enough for the answer.
