Complement System
UNIT VI
,• The complement system is a crucial part of the
immune system, playing a key role in defence
against infections.
• Defence????
• Infections????
• It consists of a complex set of proteins that work
together to enhance the immune response.
, • Part of Innate Immunity: The complement
system is a crucial component of the innate
immune system, consisting of over 30 soluble
and membrane-bound proteins that enhance
the ability of antibodies and phagocytic cells
to clear pathogens.
• Activation Pathways: It can be activated
through three main pathways—classical,
lectin, and alternative—all of which converge
at the cleavage of C3, leading to a common
terminal pathway.
