The complement cascade is a series of reactions that take place in the blood. The cascade activates the complement proteins. The result is an attack unit that creates holes in the membrane of bacteria, killing them. C3 attaches to bacteria and kills them directly. The complement pathway acts in a cascade fashion, which means the activation of one component in the complement pathway resulting in the activation of the next components. The complement system was first observed in 1888 by George Nuttall in a sheep’s blood serum.

(See also Overview of the Immune System.) The complement system is a sophisticated and systematic defense strategy that can be traced back 600-700 million years. It is traditionally considered a central part of innate immunity that enhances the lethal effect of antibodies and phagocytic cells during the defense against microbes, apoptotic and necrotic cells from an organism. There is mounting evidence that the complement cascade plays a role in the chronic as well as acute inflammation that has been associated with aneurysm formation, growth, and rupture. In effect, the physicochemical stress that occurs in intracranial arteries may lead to exposure and deposition of complement-activating factors in the aneurysm wall, which later predispose it to rupture. 2021-03-02 · Gene ID: 729, updated on 2-Mar-2021.

There are 3 major independent, but overlapping, pathways for activation of complement. The classical, lectin, and alternative pathways generate the major complement opsonin C3b and the membrane attack complex (MAC, C5b-9). Most complement proteins are enzymes which are regulated as zymogens and consequently their activation occurs by enzymatic removal of an inhibitory domain within the protein.

The plasma proteins, Factor I and C4 binding protein (C4-bp), inhibit the activity of the classical C3 convertase. 2020-06-18 2010-11-01 2012-10-04 The complement cascade enhances (i.e. complements) the ability of antibodies and phagocytic cells (a type of white blood cells) to clear microbes and damaged cells from our bodies, promotes inflammation, and attacks the pathogen’s cell membrane.

Because activated complement proteins can damage host tissues and are highly inflammatory, they are normally held inactive in the plasma. The complement cascade consists of 3 separate pathways that may be activated to converge in a final common pathway. The pathways include the "classical pathway" (including components C1qrs, C2, C4), the "alternative pathway" (including components C3, factor B, properdin), and the "lectin pathway" (a.k.a.

They interact in coordinated and regulated way to produce biologically active protein products. ACTIVATION OF COMPLEMENT CASCADE The complement cascade can be activated in 3 ways: The complement pathway is frequently referred to as a "Cascade" because of the sequential architecture by which these proteins activate one another. Because activated complement proteins can damage host tissues and are highly inflammatory, they are normally held inactive in the plasma. The complement cascade consists of 3 separate pathways that may be activated to converge in a final common pathway. The pathways include the "classical pathway" (including components C1qrs, C2, C4), the "alternative pathway" (including components C3, factor B, properdin), and the "lectin pathway" (a.k.a. mannan-binding lectin [MBL]).
