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. In most cases, the enzyme which removes the inhibitory domain is a different complement protein higher up in the complement "Cascade".

Complement cascade activation occurs via three major pathways: the classical pathway (CP), the mannose‐binding lectin pathway (MLP) and the alternative pathway (Fig. 1). Each pathway is triggered by a different type of stimulus but concertedly produced the same effector molecules.

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]). Activation of complement leads to robust and efficient proteolytic cascades, which terminate in opsonization and lysis of the pathogen as well as in the generation of the classical inflammatory Activated factor XII can cause activation of kinin system, clotting system, fibrinolytic system and the complement system. 16.

[] The genetic deficiency of early components of the classical pathway (C1q, C1r/s, C2, C4) tend to be linked with autoimmune diseases [] , whereas C5 to C9 may C3 has a central role in the complement cascade.

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.

As part of the innate immune system, elements of the complement cascade can be found in species earlier than vertebrates, most recently in the protostome horseshoe crab species, putting the origins of the system back further than was previously thought.

Page 13. MicroVue C3 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. Complement Cascade Complement cascades are activated during sepsis, and C5a, a potent complement component with procoagulant properties, has been found to be elevated in rodent models of sepsis. From: Seldin and Giebisch's The Kidney (Fourth Edition), 2008 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).

The complement cascade is a network of plasma proteins and cell surface receptors that recognize non-self-components and triggers one of the three pathways.

Deficiencies in the complement cascade can lead to overwhelming infection The complement system is an important part of the innate immune system, providing a strong defense against pathogens and removing apoptotic cells and As part of the immune system, the complement cascade can be activated by three different pathways. The classical pathway takes place when antibody/antigen The complement cascade is a potent antimicrobial immune defense that can be activated several ways (Fig. 1). The classical pathway of complement is usually 24 Nov 2020 The complement system is an ancient host defense system that traces its biologic origins to more than one billion years ago [1].
