Kurs: The complement system - from biology to clinical
2009-12-15 · Complement is a system of more than 30 proteins in the plasma and on cell surfaces, amounting to more than 3 g/L and constituting more than 15% of the globular fraction of plasma 1.This array of The term complement refers to a set of serum proteins that eliminate blood and tissue pathogens. The complement system exists in an inactive state in the plasma. Moreover, it is an extremely powerful system comprising of glycoproteins, several proenzymes, and components. I. LEARNING OUTCOMES: To Understand the : • role of complement in inflammation and the effects of specific complement deficiencies on patients. • mechanisms by which the complement system is activated and regulated. • effector molecules of complement activation and their biologic function. • role of complement in bacterial clearance and lysis.

• The term “Complement” refers to the ability of these The complement system is a collection of molecules of the innate immune system that kill pathogens directly or help phagocytes recognize and kill a pathogen. Patients with coronavirus disease 2019 (COVID-19) present a wide range of acute clinical manifestations affecting the lungs, liver, kidneys and gut. Angiotensin converting enzyme (ACE) 2, the best-characterized entry receptor for the disease-causing virus SARS-CoV-2, is highly expressed in the aforementioned tissues. However, the pathways that underlie the disease are still poorly understood The complement system helps or “complements” the ability of antibodies and phagocytic cells to clear pathogens from an organism. It is part of the immune system called the ” innate immune system ” that is not adaptable and does not change over the course of an individual’s lifetime. Complement System Complement system is a natural defence line of immune system against invasive pathogens through direct cytolysis or stimulation of phagocytosis, contributing to the inflammation and homeostasis.

When activated, the complement system produces a cascade of proteins with each step in the complement system activated by a highly specific protease. C5, near the end of the complement cascade, is split into the anaphylatoxin C5a, a powerful inflammatory substance that engages two cell surface G-protein coupled receptors, and into C5b, which is the basis for formation of the membrane attack
The complement system helps antibodies and phagocytic cells clear pathogens from an organism. The complement system consists of a number of small proteins produced by the acute phase reaction in the liver during inflammation. The complement system might play a role in diseases with an immune component and those of the central nervous system.

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. The complement system is a part of the immune system, consists of a series of proteins that interact with one another in a highly regulated manner, in order to eliminate pathogens. It helps antibodies and phagocytic cells to clear pathogens and damaged cells; promote inflammation and attack pathogen’s plasma membrane. The complement system can be activated when antibodies, which are proteins produced by cells in the immune system, bind to potentially harmful substances, or antigens. These antigens might be proteins present on the surface of a single-celled bacterium.

The complement system includes serum and membrane-bound proteins that function in both specific and non-specific immune reactions. They are activated via a chain of proteolytic cascades.

The complement system is critical in protecting ocular tissues and is also involved in constant immune surveillance of the eye. A functionally active complement system that is activated at low levels is present in the normal eye even in the absence of any inflammation.
