Summary Introduction
To determine:
The function and the mode of action of the complement system and interferon in one overview sentence.
Concept introduction:
Antimicrobial proteins are the larger proteins such as nutrient-binding proteins and they contain sites which targets specific microbial macromolecules. These proteins act largely by disrupting the structure or function of the cell membranes of the microbes.
