摘要

Different cells and molecules in mammalian body, viz. ciliated epithelial cells, macrophages, digestive enzymes, lysozyme, bacteriolysin, transferin, C-reactive protein, complement protein (CP) constitute the first line of defense against pathogens and are components of innate immune system. Complement system (CS) consists of 35 distinct soluble and membrane-associated proteins, circulate in blood and tissue fluids and play crucial role in host defense. Immediately after the pathogen is encountered, in classical pathway, antigen-antibody complex activates the CS; recognition of pathogen-associated molecular pattern (PAMP) by lectins activates CS in lectin pathway and it is activated by cell wall components of pathogen in alternate pathway. Activated components of CS are involved in bacterial lysis, chemotaxis and pathogen opsonization. Once pathogen-specific antibodies are generated, CS aids in clearance of immune complexes and pathogen elimination. Bridging innate and adaptive immune responses functionally, CS allows an integrated defense to invading pathogens, can elicit highly-efficient immune responses, both inflammation and to pathogenic organisms, 'complementing' the antibacterial properties of antibody.
