NettetThe major functions of the innate immune system are to: recruit immune cells to infection sites by producing chemical factors, including chemical mediators called cytokines activate the complement cascade to identify bacteria, activate cells, and promote clearance of antibody complexes or dead cells NettetSpecific immune responses are triggered by antigens. Antigens are usually found on the surface of pathogens and are unique to that particular pathogen. The immune system responds to antigens by producing cells that directly attack the pathogen, or by producing special proteins called antibodies.
