Classical Complement Pathway Overview
The classical complement pathway is a tightly regulated enzymatic cascade initiated mainly by antibody-antigen interactions. It orchestrates multiple defense mechanisms—opsonization, chemotaxis/inflammation induction, direct cell lysis—and links adaptive immunity with innate effector functions through its unique recognition mechanism centered around antibody engagement.
Mechanism of Action
Inhibition of C1 activation or downstream complement components
Biological Functions
Opsonization
Chemotaxis
Cell lysis
Inflammation
Immune response
Clearance of immune complexes
Disease Associations
Infection
Autoimmune diseases (e.g., SLE)
Inflammation
Safety Considerations
- Increased susceptibility to infections with complement inhibition
- Potential for off-target effects on other complement pathways
Interacting Drugs
C1 inhibitors
