complement receptors


complement receptors
cell-surface receptors for products of complement reactions, with roles including recognition of pathogens, phagocytosis, adhesion, and clearance of immune complexes. At least nine types exist, with the best characterized being CR1–4, which bind C3 fragments already bound to a surface. Other complement receptors are named according to ligand (e.g., C5a receptor).
