Interferon’s (IFNs) are a group of signaling proteins made and released by host cells in response to the presence of pathogens, such as viruses, bacteria, parasites, or tumor cells. Interferon synthesis occurs primarily in response to viral single-strand ­ ed or double stranded RNA that are either the genetic material of RNA viruses or a product of viral transcription. Interferon’s are named for their ability to "interfere" with viral replication by protecting cells from virus infections.
