…secondary mechanism is known as immunological memory, and it is responsible for the lifetime immunities to diseases such as measles that arise from childhood exposure to the causative pathogen. Immunological Memory. The adaptive immune system possesses a memory component that allows for an efficient and dramatic response upon reinvasion of the same pathogen. Memory is handled by the adaptive immune system with little reliance on cues from the innate response. During the adaptive immune response to a pathogen that has not been encountered before, called a primary response, plasma cells secreting antibodies and differentiated T cells increase, then plateau over time.
