Complement proteins bind to antibodies on the microbe’s surface, signaling phagocytes to recognize and destroy the microbe. Complement proteins also induce the inflammatory response and lyse pathogens. A cell will produce signaling proteins called interferons when infected by a pathogen. Interferons increase the resistance of neighboring cells to infection and are often triggered by viral RNA.
