Activation of the complement system gives rise to a number of molecular the recognition molecule of the classical complement pathway [reviewed in 20, 130].

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 system is activated cascadically via three distinct major routes: classical pathway (CP), alternative pathway (AP) or lectin pathway (LP). The unique factors associated with the latter are collectins (mannose-binding lectin, collectin-10, collectin-11), ficolins (ficolin-1, ficolin-2, ficolin-3) and proteins of the mannose-binding lectin-associated serine protease (MASP) family Se hela listan på microbeonline.com Complement triggers the following immune functions: Membrane attack – by rupturing cell wall of bacteria. ( Classical Complement Pathway) Phagocytosis – by opsonizing antigens. C3b has most important opsonizing activity.

As a phylogenetically old system complement is now regarded as a part of innate immunity. But it is much more than that. It bridges innate and adapted immunity

The complement system consists of about 30 proteins designated by the numbers C1 through C9 (components of the classical pathway), in addition to various factors of the alternative pathway (e.g. B, D, H, and I factors, properdin and others). These proteins act in a series of steps, where the activated component of complement splits the next one

Alternative pathway: Sometimes microorganisms or its toxins can directly activate complement system, which is an innate and non-specific reaction. Sooner microorganisms are coated by complement molecules leading to its uptake by phagocytosis.

35 As shown in Figure 5A, addition of EDTA or EGTA to plasma before addition of PF4/heparin eliminated complement activation.

LECTIN PATHWAY • Its function in the complement pathway is similar to that of C1q, which it resembles in structure. • After MBL binds to the surface of a cell or pathogen, MBL- associated serine proteases,MASP-1 and MASP-2, bind to MBL. • The active complex formed by this association causes cleavage and activation of C4 and C2. Pathway complement components are cleaved into two fragments; a larger active serine protease which stays on the pathogen surface (such as C3b, C4b and C5b) and a smaller fragment that is released to act as a soluble mediator (including C3a, C4a, C5a). Participants in the complement activation pathways circulate in the plasma and are present at a lower concentration in other body fluids as well as in the intracellular and interstitial spaces. The complement cascade continues in a manner analogous to the classical pathway.
