Complement proteins play direct key roles in host microbial defense. They complement the actions of specific antibodies and aid the processing and removal of immune complexes.   The complement system is proinflammatory, and multiple complex control factors are necessary to ensure that potential tissue damage is limited or minimized. Disease states occur with deficiencies in complement proteins (which can cause increased risk of invasive bacterial infections, and may be associated with autoimmune disease), or defects of factors controlling, focusing, and limiting complement activation. Complement deficiencies can be inherited or acquired (secondary to a complement-consuming disease state).
