Nonspecific Immunity, Complement System
... After C3b is generated, it can bind to factor B. Factor D can then cleave factor B to form the C3 convertase (C3bBb). The attachment of properdin (P) stabilizes the complex and allows it to generate more C3b. The end result is the deposition of large amounts of C3b on the pathogen. Adapted from Lisz ...
