Final answer:
Antimicrobial proteins of the innate immune system include interferons and complement. Interferons respond to pathogens by signaling the immune system, while the complement system consists of proteins that help in destroying pathogens and promoting inflammation.
Step-by-step explanation:
The examples of antimicrobial proteins of the innate immune system are interferons and complement. Interferons are proteins released by host cells in response to the presence of pathogens like viruses, bacteria, parasites, and tumor cells. They signal the immune system and guide the response to help in eradicating pathogens. The complement system, on the other hand, is an array of about 20 proteins that are part of the immune system and can destroy extracellular pathogens. It is activated by infection and enhances the ability of antibodies and phagocytic cells to clear microbes and damaged cells from an organism, promote inflammation, and attack the pathogen's cell membrane.
