Most complement proteins are produced in the liver.
The origin and contribution of complement proteins to synapse pruning in development and AD are not well understood and require further investigation.
Depending on the local environment and the circumstances under which complement proteins are generated, they may contribute to cell and tissue homeostasis, to benefit or burden inflammation, or to promote tissue regeneration versus fibrosis [7].
The fragment C3b of C3 is the crucial active component that triggers the cleavage of a variety of complement proteins (C5-C9).

Bradykinin has been shown to be responsible, via activation of the bradykinin [B.sub.2] receptor, for most of the physiologic changes that cause the acute symptoms of HAE; these changes include vasodilation, increased tissue permeability, and smooth-muscle contraction." The complement pathway, however, remains important in the understanding of HAE, as complement proteins such as C4 and Clq are key to laboratory testing and diagnosis (see section entitled, "Differential diagnosis").
Quantification of IgE and cytokines in serum: Serum concentrations of IgE, cytokines such as IL-4, IL-10 and complement proteins such as C3c and C4 were quantified by nephelometric analysis using Nephelometer (BN ProSpec, Dade Behring, Marburg, Germany).
The complement protein C1 esterase inhibitor (C1-INH) is an acute phase protein [13], the plasma level of which can possibly increase in acute phase responses.

One of these tests measures the breakdown products of a blood complement protein known as Factor B.
Some of the components that serve as linker between innate and adaptive immunity include dendritic cells, macrophages, and complement protein. Dendritic cell and macrophages can both function in innate immunity by phagocytosing pathogens or innate immunity, but they also contribute to adaptive immune responses by serving as antigen-presenting cells for T cell activation [34].
