Background
C5a is a protein fragment released from cleavage complement component C5 by protease C5-convertase into C5a and C5b fragments. C5b is important in late events of complement cascade, whereas C5a acts as highly inflammatory peptide. C5a plays a key role in increasing migration and adherence of neutrophils and monocytes to vessel walls. White blood cells are activated by upregulation of integrin avidity, the lipoxygenase pathway and arachidonic acid metabolism. C5a also modulates the balance between activating versus inhibitory IgG Fc receptors on leukocytes, thereby enhancing theautoimmune response. C5 is initially expressed in the hepatocyte while its synthesis can also be found in macrophages that may cause local increase of C5a.
