Autoantibodies Against C3b—Functional Consequences and Disease Relevance
The complement component C3 is at the heart of the complement cascade. It is a complex protein, which generates different functional activated fragments (C3a, C3b, iC3b, C3c, C3d).

The role of salivary and intestinal complement system inhibitors in the midgut protection of triatomines and mosquitoes. [PDF]
Saliva of haematophagous arthropods contain biomolecules involved directly or indirectly with the haematophagy process, and among them are encountered some complement system inhibitors.

Staphylococcus aureus proteins Sbi and Efb recruit human plasmin to degrade complement C3 and C3b.
Upon host infection, the human pathogenic microbe Staphylococcus aureus (S. aureus) immediately faces innate immune reactions such as the activated complement system. Here, a novel innate immune evasion strategy of S. aureus is described.

Characterization of Binding Properties of Individual Functional Sites of Human Complement Factor H
Factor H exists as a 155,000 dalton, extended protein composed of twenty small domains which is flexible enough that it folds back on itself. Factor H regulates complement activation through its interactions with C3b and polyanions.

Structural Model for Factor X Inhibition of IgM and Complement-Mediated Neutralization of Adenovirus
Adenovirus has strong therapeutic potential as an oncolytic virus and gene therapy vector. However, injecting human species C serotype 5 adenovirus, HAdv-C5, into the bloodstream leads to numerous interactions with plasma proteins that affect viral ...
