Background: Cold agglutinin disease is a rare autoimmune hemolytic anemia characterized by hemolysis that is caused by activation of the classic complement pathway. Sutimlimab, a humanized monoclonal antibody, selectively targets the C1s protein, a C1 complex serine protease responsible for activating this pathway.
Participants in the complement activation pathways circulate in the plasma and are present at a lower concentration in other body fluids as well as in the intracellular and interstitial spaces. The components in plasma are predominantly synthesized in the liver, while the components at other sites represent a combination of local synthesis (many cell types) and filtrates from plasma ( table 1 ).

Because activated complement proteins can damage host tissues and are highly inflammatory, they are normally held inactive in the plasma. The classic complement pathway is triggered when antibody-antigen complex interact with C1-complex, which consists of C1q, two molecules of C1r, and two molecules of C1s. The C1-complex cleaves C2 and C4, which then form C3 convertase (C4b2a). C3 is then cleaved by the C3 convertase, and forms C5 convertase in association with C4b and C2a. The complement pathway is a part of the innate immune system. The complement pathway is made up of over 30 heat-labile Complement proteins, which are found in human blood plasma. These proteins are synthesized by the liver, intestinal mucosa, spleen, and macrophages. After synthesis, they circulate in an inactive form in plasma and tissue fluids.
The complement pathway is a regulated cascade of proteins that supports or complements (hence the name) the activity of antibodies and phagocytes in clearing infections.

The Classical Pathway - The Complement System (Part IV) (FL-Immuno/16) - YouTube. The classical pathway is one of three activation pathways of the complement system, which is a major contributor to the defense of infections, clearance of pathogens, removal of apoptotic/necrotic cells, and maintenance of homeostasis.

We have identified and characterized a class of complement inhibitors from biting ticks. Utilizing both cryoelectron Three biochemical pathways activate the complement system: the classical complement pathway, the alternative complement pathway, and the lectin pathway. The following are the basic functions of the complement: opsonization (enhancing phagocytosis of antigens); chemotaxis (attracting macrophages and neutrophils); cell lysis (rupturing membranes of foreign cells); and clumping (antigen-bearing Se hela listan på microbenotes.com The alternative complement pathway is now activated.
These proteins act in a series of steps, where the activated component of complement splits the next one
The Classical Pathway. The classical pathway is activated when a complement protein called C1q binds either directly to a pathogen, or onto an antigen-antibody complex. This will then trigger cleavage of the subsequent complement proteins in the cascade, resulting in production of C3 convertase and it’s downstream effects. The Fc portion of IgG and IgM can activate the classical complement pathway by enabling the first enzyme in the pathway, C1, to assemble.

The complement system is a crucial antimicrobial system in the human body. However, controlling its regulation is essential, and failure to do so is implicated in a number of clinical inflammatory pathologies leading to great interest in therapeutic complement inhibition. We have identified and characterized a class of complement inhibitors from biting ticks. Utilizing both cryoelectron
Santosh Stages of complement Activation Three main stages in the activation of complement by any pathway are Formation of C3 convertage Formation C5 convertage Formation of membrane attack complec (MAC) • The initiation and formation of C3 convertage are different in classical and alternative pathway.
Alternative complement pathway function, or AH50, can be quantified by measuring the hemolysis of rabbit erythrocytes after incubation with serum . Despite its role in immune function, overexuberant activation of the complement system is thought to contribute to the pathogenesis of sepsis and other critical illnesses (23, 24).

The Fc portion of IgG and IgM can activate the classical complement pathway by enabling the first enzyme in the pathway, C1, to assemble. Complement Activation Classical Pathway Steps The classical pathway is initiated by IgM or IgG antigen/antibody complexes binding to C1q (first protein of the cascade) leading to activation of C1r, which in Complement Pathway. The complement pathway is part of the innate immune system that complements the ability of immunoglobulins and phagocytic cells to clear microbes and damaged cells, promotes inflammation through recruiting both the innate and adaptive immune cells, and attacks the pathogen's cell membrane itself. Alternative pathway: Sometimes microorganisms or its toxins can directly activate complement system, which is an innate and non-specific reaction.
