The Adaptive Immune Response“Match me perfectly and I’m neutralized” Kathy Huschle Northland Community and Technical College Adaptive Immune Response in contrast to the innate immune response which we are basically born with, the adaptive immune response is an ever developing system it continues to mature throughout our life Adaptive Immune Response in most cases as each new microbial invader is encountered, our adaptive immune response initiates a specific attack against the invader generally this invader is remembered and that “memory” is readily available in the case of a second or subsequent attack from the same invader Adaptive Immune Response this system is an extremely complex system to which we will attempt to gain a basic understand immunologists are continually discovering many facts about the adaptive immune response Adaptive Immune Response the adaptive immune response is learned or acquired recognizes specific substances foreign to the body is essential for life Adaptive Immune Response other terms used for the adaptive immune response include acquired immunity specific immunity though at one time thought to function exclusive of the innate immune system, research is now discovering a correlation between the two systems regardless of a correlation or not, the failure of our immune system results in mortality Adaptive Immune Response adaptive immune response is characterized by specificity memory learned ability to recognize (acquired) pathogens which allows the body to usually only suffer once from that particular pathogen Components of the Adaptive Immune System antigens antibodies lymph system lymphocytes B cells T cells NK cell (Natural Killer) Antigens the term antigen derives from the two words antibody generator most antigens are proteins or large polysaccharides Antigens often a component of invading microbes, such as the capsule, cell wall, flagella, toxin particular chemical that will activate the adaptive immu
