Humoral immunity defines the production of an antibody and associated processes that go with it involving Th2 activation and production of cytokines, formation of germinal centre and switching of isotype, affinity maturation and generation of memory cell. It also defines the antibody’s effector functions that involve neutralisation of pathogen and toxin, classical complement activation and elimination of pathogen.

”Complement system is the biochemical cascade of innate immunity system which helps plain pathogens from the organism.”- What does it constitute of?

Complement system is the biochemical cascade of innate immunity system which helps plain pathogens from the organism. It is inherited from several tiny plasma proteins which work together for interrupting plasma membrane of target cells resulting in cytolysis of cells. Complement system is made up of 35 soluble cell bound proteins, 12 of which are associated directly in complement pathways. Major part of these proteins move on as zymogens that are dormant until proteolytic cleavage. Complement system is associated with the activation of both innate and acquired immunity.
