Study Notes
Complement System Characteristics
- A characteristic of the complement system is that it is a part of the immune system that helps eliminate pathogens from the body.
Complement Protein Production
- Complement proteins are mainly produced in the liver.
Complement Factor Activation
- The mode of activation of complement factors is known as a cascade reaction.
Effects of Activation
- When complement factors become activated, they are proteolytically cleaved into smaller fragments.
Complement Activation Pathways
- There are three pathways for complement activation: the classical pathway, the alternative pathway, and the lectin pathway.
Complement System Characteristics
- The complement system is NOT an adaptive immune response.
Complement Fragmentation
- The small fragment produced when complement factors become activated is called an anaphylatoxin.
Antibody-Dependent Complement Activation
- The classical pathway of complement activation is triggered by the binding of antibodies to antigens.
Complement Amplification
- Complement factor C3 is responsible for the amplification of the complement activation process.
Complement Factor Location
- Complement factors are NOT normally found in the eyes.
