Classical pathway complement
WebThe complement system is an important part of the innate immune defense. Complement proteins interact in a cascade in order to opsonize pathogens and induce a series of inflammatory responses which help immune cells fight infection and maintain homeostasis. WebThe classical complement pathway is initiated by the binding of complement protein 1q (C1q) to an antigen–antibody complex at the surface of a pathogen or a host cell. This …
