 Synthesized in liver as inative precursors and are activated by proteolysis durig their interaction in a sequential manner.  Also produced by blood monocytes, tissue macrophages and epithelial cells of he gastrointestinal and genitourinary tract. Complement activation triggers powerful effector mechanisms against which host cells must be protected.

( Classical Complement Pathway) Phagocytosis – by opsonizing antigens. C3b has most important opsonizing activity. ( Alternative Complement Pathway) Inflammation – by attracting macrophages and The complement system represents the first response of the host immune system to SARS-CoV-2 infection, but there is growing evidence that unrestrained activation of complement induced by the virus in the lungs and other organs plays a major role in acute and chronic inflammation, endothelial cell dysfunction, thrombus formation, and intravascular coagulation, and ultimately contributes to multiple organ failure and death. Once activated the complement system has several effects, including: Opsonisation Lysis of pathogens Chemotaxis Inflammation The complement system consists of a tightly regulated network of proteins that play an important role in host defense and inflammation.

Indeed, the serum complement system, which is one of the major defence systems in the on the surfaces of microorganisms-to give lectin pathway activation.

This is attributed to the fact that C5a renders neutrophils more adherent and thereby prone to aggregation within the pulmonary vasculature. The complement system is an enzyme cascade that helps defend against infection.

Complement System Classical Pathway. This pathway involves complement components C1, C2 and C4. The pathway is triggered by Alternative Pathway. This pathway involves various factors, B, D, H & I, which interact with each other, and with C3b, Mannose-binding Lectin Pathway. This pathway is Complement Activation during Normal Homeostasis and Pathogen Infection The central component of the complement system is C3. The activation of each of the three pathways (CP, LP, and AP) results in cleavage of inactive C3 protein into the functional fragments C3a and C3b. The complement activation occurs via three pathways; which are: Classical pathway Alternative pathway Lectin pathway (or mannose binding lectin pathway) Santosh  Complement system represents a group of about 30 proteins which augment or complement the immune response.

Activation of the complement system generates antibacterial

The complement system is commonly activated by one of 3 triggers. The lectin pathway Complement activation initiated by the binding of COMPLEMENT C1 to ANTIGEN-ANTIBODY COMPLEXES at the COMPLEMENT C1Q subunit.

These regulatory proteins may be classified into two categories: • The complement system is a key player in innate immunity. Despite a few reports of local complement activation, there is a lack of evidence that the degree of systemic complement activation occurs early in COVID-19 patients, and whether this is associated with respiratory failure. Complement activation represents the dynamic interplay among the different pathways, the control processes, and other protein systems and cells in the local environment.
