A) Interferon,produced by a host cell in response to viral attack,is secreted and enters neighboring cells,stimulating the production of antiviral proteins in anticipation of an invasion.
B) Interferon stimulates the hypothalamus to raise the body temperature,increasing metabolism and preventing the growth of temperature-sensitive pathogens.
C) Interferon comprises a team of blood proteins that are activated in a cascade,ultimately leading to pathogen cytolysis,inflammation and enhanced phagocytosis.
D) Interferon binds to cell surfaces and induces changes in genetic expression,eliminating not only pathogens,but cancer cells also.
