Study Notes
Complement Protein Synthesis
- Hepatocytes are the primary cells responsible for synthesizing complement proteins.
- Complement proteins constitute approximately 5-10% of total serum proteins in normal serum.
Other Sources of Complement Proteins
- Besides hepatocytes, macrophages and certain epithelial cells also produce significant amounts of complement proteins.
Response to Infection and Vaccination
- Complement levels increase in response to infection or following vaccination, enhancing the immune response.
