ALTERNATIVE PATHWAY. This is a primitive defense system. In this pathway, there is a bypass of C1, 4, 2 and there is direct stimulation of C3. This is predominantly a non-antibody initiated pathway. The activator of the alternative complement pathway are: Polysaccharides complex from the surface yeast cells. Bacterial polysaccharides and endotoxin.

Mar 31, 2016 The complement system is an integral part of innate immunity that detects and eliminates invading pathogens through a cascade of reactions.

It is initiated by spontaneous hydrolysis of C3 at high C3-concentrations in The classical pathway is involved in elimination of pathological immune complexes Abstract : The complement system is critically involved in defence against Nancy RickeyWork Related · Complement system-Classical and Alternative pathway Biomedicinsk Analytiker, Medicinsk Teknologi, Cellbiologi, Immunförsvar. from ANCA-associated vasculitis patients show an increased capacity to activate the complement system via the alternative pathway after ANCA stimulation. luation of alternative disposal systems will be perform- ed in 1990's.

Complement System: Classical and Alternative Pathways. Complement is a system of enzymes and proteins contributing to the lysis of target cells. The complement system includes serum and membrane-bound proteins that function in both specific and non-specific immune reactions. They are activated via a chain of proteolytic cascades.

C3 cleavage may result in formation of the membrane attack complex (MAC), the cytotoxic component of the complement system. MAC causes lysis of foreign cells. GVB ++ allows all complement pathway activation whereas GVB 0 MgEGTA only allows alternative pathway activation.

As such even a small signal can lead to the rapid activation of many thousands of complement molecules – this is important in the immune response as pathogens are also able to replicate very quickly within the body.

Sooner microorganisms are coated by complement molecules leading to its uptake by phagocytosis. The terminal stage of the complement pathway involves creation of the membrane attack complex, which is known as lytic unit. The C5 convetases are generated from C4b2a of the classical and C3bBb of the alternative pathway by addition of another C3b molecules. Accordingly, the alternative complement pathway is one element of innate immunity.

The 3 activation pathways converge into a final common pathway when C3 convertase cleaves C3 into C3a and C3b (see figure Complement activation pathways). C3 cleavage may result in formation of the membrane attack complex (MAC), the cytotoxic component of the complement system. MAC causes lysis of foreign cells.

THE ALTERNATIVE PATHWAY IS AB-INDEPENDENT The activation of alternative pathway doesn’t need Ab; thus, It is a component of the innate immune system. It is initiated by cell-surface constituents that are foreign to the host, e.g., bacterial cell wall. C1, C4 and C2 are not involved in the alternative pathway.
