Regulation of the complement system • Inclusion of highly labile components that undergo spontaneous inactivation if they are not stabilized by reaction with other components. • A series of regulatory proteins (regulators of complement activation [RCA] gene cluster - chromosome 1 in humans).

The complement system, which is actually part of our immune response, consists of over thirty different inactive proteins circulating in our blood stream.

The complement system has the potential to be extremely damaging to host tissues meaning its activation must be tightly regulated.

The complement system is made up of a number (mostly 30) of distinct serum (blood plasma) and membrane proteins which mostly assist the humoral branch of the immune system. As after initial activation, the various complement components interact sequentially to generate reaction products that facilitate antigen clearance and inflammatory response.

There are many regulatory systems to prevent unwarranted damage to the human host. The following are regulators of the complement system: Level of antibody. It is the first regulatory step in the classical pathway.

Regulation of Complement System Since the complement system involves the formation of many biologically active substances, there are many regulatory systems to prevent unwarranted damage to the human host. The activities of the different complement components activated at each stage of the cascade are regulated by several mechanisms.

The complement system found in the blood of mammals is composed of heat labile substances (proteins) that combine with antibodies or cell surfaces. This complex, multicomponent system is composed of about 26 proteins. The “complement cascade” is constitutive and non-specific but it must be activated in order to function.

It has been generally accepted that, together with the C system, they contribute to host defense, tissue clearance and regulation of inflammation.
