The Immune response Lesson 1 The NonSpecific Response

The Immune response – Lesson 1

The Non-Specific Response (attack ANYTHING foreign to the body!) The non-specific response quickly targets a w_____ range of pathogens and foreign substances. P_______, inflammation and the antimicrobial proteins l_____ and interferons are all part of this immune response. • Lysozyme is an e_____ that disrupts the cell walls of specific types of bacteria by digesting the p______. It is found in human tears, saliva and l_____. • I______ are proteins produced by virus-infected body cells in response to the virus. Interferons trigger the production of a second protein that inhibits viral replication. The Specific Response (targets particular pathogens within the body!) The specific or adaptive immune response can target a specific pathogen, although it is s____ to act than the non-specific response. It features two main types of response to pathogens: • the c____-m____ response involves highly-specialized cells that target pathogens inside cells. • the h______ or antibody-mediated response targets pathogens in body fluids with antibodies.
