Activation of complement is the result of a cascade of proteolytic steps involving three different pathways: The classical or antibody dependent pathway - where activation is triggered by antibody-target interactions. The complement system is made up of over 30 proteins organized in the 3 activation pathways—the classical, the lectin, and the alternative —that converge on the cleavage of central component C3 by enzyme complexes—the classical/lectin and the alternative C3 convertases—that generate activation products (C3a, C4a, C3b, and C4b) that function to eliminate pathogens through opsonization Complement activation mediates pathogen clearance by the formation of the membrane-attack complex, opsonization for phagocytosis, and modulation of inflammation by chemotactic immune-regulatory anaphylatoxins . Hence, alternative pathway activity may provide control of bacterial infections as a protective mechanism of host defense.

Page 23. Faktor H. Faktor H-relaterade proteiner 1-5. The complement system is activated in a wide spectrum of CNS diseases and is suggested to play a role in degenerative phenomena such as elimination of Properdin binds independent of complement activation in an in vivo model of anti-glomerular basement membrane disease A bacterial infection will lead to the generation of specific antibodies, which are linked to complement activation through the classical pathway.

complement and contact systems. Activation of these systems will inevitably result in recruitment and activation of cells, which in turn are able to release inflammatory mediators (2). The main focus of this work is on the initial blood-biomaterial contact and how the complement system is activated. Both the mechanisms that

2 A role for the complement system in the pathogenesis of SARS-CoV-2 infection (ie, COVID-19) was suspected based on the similarities to the clinical presentation and the autopsy findings observed in thrombotic microangiopathies: paroxysmal nocturnal hemoglobinuria 2021-02-24 · Activation of the Complement System There are three ways to activate the complement system, involving different molecules initially but converging to produce the same effector molecules. Each involves activation of enzymes that cleave their substrates to form a cascade, so that the complement response is amplified.
