Human Complement Fragment C4a (C4a) Protein

Background

C4B is a component of the classical and lectin pathways of the complement system, which plays an essential role in immune defense by promoting pathogen clearance, inflammation, and immune complex removal C4B is involved in the formation of the C3 convertase complex, which activates the complement cascade and results in the destruction of pathogens via opsonization and lysis It also participates in the regulation of immune responses and plays a role in clearing immune complexes that could otherwise contribute to tissue damage C4B is implicated in the Chido/Rodgers blood group system, which is used in transfusion medicine C4B deficiency or dysfunction is associated with autoimmune diseases, including systemic lupus erythematosus, where excessive complement activation exacerbates tissue damage The balance of C4B in the complement system is crucial for maintaining immune homeostasis and preventing chronic inflammation
