The activation of complement during platelet activation is incompletely understood. We sought to explore the formation of C5b-9 and anaphylatoxins binding to collagen-activated platelets. C5b-9, anaphylatoxins C3a, C4a and C5a, and anaphylatoxin receptors C3aR1 and C5aR were measured by flow

Activation of serum complement triggers Th17 cell-dependent spontaneous autoimmune disease in an animal model. In genetically autoimmune-prone SKG mice, administration of mannan or beta-glucan, both of which activate serum complement, evoked Th17 cell-mediated chronic autoimmune arthritis.
