Easy tutorial mnemonic animation immunology.

Alternative complement pathway animation. This video by quidel provides a detailed molecular overview of the classical and alternative pathways for the complement system. Shomus biology 17733 views. The alternative pathway is slower than the classical pathway the alternative complement pathway initiation of the alternative pathway c3 contains in unstable thioester bond. The cells inner integrity is compromised and it dies animation of the classical pathaway overview the alternative pathway the alternative pathway is part of the non specific defense because it does not need antibodies to initiate the pathway.

Membrane attack complex mac. The alternative pathway the complement system part ii fl immuno14 frank lectures. And the lectin pathway is activated by a plasma lectin. Alternative pathway protein factor b then combines with the cell bound c3b to form c3bb.

The alternative pathway of the complement system is an innate component of the immune systems natural defense against infections. Animation of activation of the alternative complement pathway and formation of c3 convertase activation of the alternative complement pathway begins when c3b or c3i binds to the cell wall and other surface components of microbes. The complement system cs has recently been recognized as a bridge between innate and adaptive immunity that constitutes a very complex mechanism controlling the clearance of pathogens cellular debris and immune complexes. The classical pathway is activated by certain isotypes of antibodies bound to antigens.

Complement system alternative pathway animation duration. The pathway is triggered when the c3b protein directly binds a microbeit can also be triggered by foreign materials and damaged tissues. The complement system is a multi protein cascade of proteins that. The alternative pathway is activated on microbial cell surfaces in the absence of antibody.

Out of three known pathways of complement activation the alternative pathway ap plays a critical role in host defense by amplifying the complement response.
