A cell infected by a virus can secrete proteins called ? that will prevent viral replication in neighboring cells. this is a type of ? immunity.

Solution

Interferons (IFNs) are a group of signaling proteins made and released by host cells in response to the presence of several pathogens, such as viruses. IFNs 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. Interferon play a main role in the innate immune response.
