Adaptive Immunity “In contrast to the innate immune response, which is always ready to respond to patterns that signify damage or invasion, the adaptive immune response matures throughout life, developing from the immune system arsenal the effective response against specific invaders as each is encountered.” “An important hallmark of the adaptive immune response is that it has memory, a greatly enhanced response to re-exposure.” Key to understanding adaptive immunity is the interactions between antigens and immune- system molecules, such as antibodies. Also important is the concept of tolerance, which is the ability of the immune system to ignore common body molecules.
