Immunology

chemical barriers include inflammation, phagocytosis and adaptive immunity. In addition to acute phase reactants present in serum that are activated with injury, infection and trauma

• C-reactive protein, binds to phagocytic cells and promotes phagocytosis by activation of complement, opsonization and precipitation , binding is calcium dependent and levels peak at 48 hours

• Serum amyloid A, activates monocytes and macrophages to produce inflammatory response, produced in liver and transported by HDL to infection site

• complement, functions in opsonization and chemotaxis and lysis of cells
