Activation of the complement system generates antibacterial peptides.

The complement system represents an evolutionary old and significant part of the innate immune system involved in protection against invading microorganisms. Here, we show that the anaphylatoxin C3a and its inactivated derivative C3a-desArg are antibacterial, demonstrating a previously unknown direct antimicrobial effect of complement activation. The C3a peptide, as well as functional epitopes ...

Thrombin generates previously unidentified C5 products that support the terminal complement activation pathway.

The coagulation and complement pathways simultaneously promote homeostasis in response to injury but cause tissue damage when unregulated. Mechanisms by which they cooperate are poorly understood. To delineate their interactions, we studied the effects of thrombin and C5 convertase on C5 in purified and plasma-based systems, measuring release of the anaphylatoxin C5a, and generation of C5b, the...

Antibacterial Peptides: A Review

Antibacterial peptides (APs), small molecules composed of less than fifty amino acid residues, are important components of the innate immune system. APs are produced by almost all living organisms in a defense strategy against invading pathogens. APs can be divided into many subtypes following different criteria: origin, size, structure, mechanism of action, etc... Despite their great diversity...

Anca-associated Vasculitis and Complement System Activation

Small vessel vasculitides associated with anti-neutrophil cytoplasmic autoantibodies (ANCA) are severe systemic diseases that may affect any organ. Increasing clinical and experimental evidence indicates that ANCA are causally involved in disease pathogenesis mainly through activation of neutrophils resulting in endothelial cell injury. Recent studies suggest a previously unsuspected but crucia...
