Quizplus · Accepted Answer

Interferons are small proteins that are produced and secreted by virus-infected cells. They help defend nearby cells that have not yet been infected by activating the immune system and preventing the virus from replicating within those cells. Haptens are small molecules that can bind to large proteins to become immunogenic, pyrogens are substances that cause a fever, and antigens are molecules that the immune system recognizes as foreign and can generate an immune response against.
