The complement system is an enzyme cascade that helps defend against infection. Many complement proteins occur in serum as inactive enzyme precursors (zymogens); others reside on cell surfaces. (See also Overview of the Immune System.)

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.

Complement cascade

complement cascade. Immunology A complex, multimolecular biologic system with ± 25 different proteins that self-assemble on cell surfaces, functioning in concert with the specific immune systems to mediate host reactions and anti-microbial defense; the coup de grâce for the hapless target cell is the polymerization of C9 on its surface, which forms 1990-11-09 2009-12-15 Complement C6 Hu Competitive Saliva, Milk, Urine, Serum, Plasma, 0.7 ng/ml 25 - 2.5 ng/ml ab125965 Cell culture extracts Complement C7 Hu Competitive Cell culture supernatant, Saliva, Milk, 0.6 ng/ml 10 - 1 ng/ml ab125964 The term complement infers that the complement cascade is an accessory of the immune system. Indeed, when Paul Ehrlich coined the term in 1899, its main function was thought to “complement” the effect of antibodies. 2021-02-13 complement cascadeopsonisationChemotaxisC9 complexbasic textureless 3D made 5y ago A dysregulated complement cascade has been shown to relate to cell activation, defective complement mediated clearance and possible cognitive decline in AD patients. Porphyromonas gingivalis , a putative keystone pathogen of periodontal disease, has been reported to be associated with human AD. 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.

Predictive Value of Donor-Specific and Complement-Binding HLA-Antibodies in cascade of COMPLEMENT ACTIVATION via the CLASSICAL COMPLEMENT

The complement system was first observed in 1888 by George Nuttall in a sheep’s blood serum. Proteins that take part in the complement system are called complements that collectively work as a biological cascade; the sequence of reactions, each being the catalyst for the next. Jules Bordet (1895) identified complements as heat-sensitive components in the blood, bearing non-specific antimicrobial activity. The complement system is composed of about 20 different proteins released into the blood after production in the liver.

The complement system, also known as complement cascade, is a part of the immune system that enhances (complements) the ability of antibodies and phagocytic cells to clear microbes and damaged cells from an organism, promote inflammation, and attack the pathogen's cell membrane.

The encoded protein is part of the membrane attack complex that can be incorporated into the cell membrane and cause cell lysis. 13 Aug 2020 The classical complement pathway is the main pathway by which the complement system occurs.

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. In the complement cascade, a panel of soluble molecules rapidly and effectively senses a danger or damage and triggers reactions to provide a response that discriminates among foreign intruders, cellular debris, healthy and altered host cells (Ricklin D et al. 2010).

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]).
