Complement activation Promotes
- Activation of immune system
- Opsonization
Leads to inflammation and
tissue damage
Chronic Activation
APR produces by
hepatocytes
protein inactivated form
zymogen
protein activated form
holoenzyme
plasma complement proteins are synthesized in
liver
main goal of complement system
cell lysis
two major APR
- C-reactive protein
- Serum amyloid A
plasma complement proteins synthesized in liver except in
C1
C1 is produced and composed of what?
-produced by epithelial cell and factor B
- composed of adipose tissue
Early complement components
C1, C2, C3, C4
3 complement system or pathway
- classical pathway
- alternative pathway
- lectin pathway
plays a major role as natural defense system
antibody independent pathway
