Biochem/physiol Actions
The complement system is an important constituent of innate immunity. It participates in the first line of defense against microbial infections, altered host cells, and removal of immune complexes and injured cells. The complement system comprises more than thirty components such as the plasma proteins produced by the liver, membrane proteins expressed on the cell surface, cytokines, and hormones. The complement proteins come together to opsonize the pathogens and initiate a cascade of inflammatory responses serving the immune cells to fight the infection and maintain homeostasis.
