Adaptive immune system - Wikipedia

Witrynathese immune receptors can persist in the host for life, providing immunologic memory and the capacity for rapid response in the event of re-exposure. Cells of the adaptive immune system include the effectors of cellular immune responses, the T lymphocytes, which mature in the thymus, and antibody-producing cells, the B lymphocytes, WitrynaAdaptive immune system has specificity and memory. The adaptive immune system takes some time: 1-2 weeks, to mount a full-fledged response to any pathogen or biological macromolecule that it sees for the first time. However, the second time it sees the same pathogen or macromolecule, it mounts an immediate, even stronger response. WitrynaAdaptive immunity occurs later, as it relies on the coordination and expansion of specific adaptive immune cells. Immune memory follows the adaptive response, when mature adaptive cells, highly specific to the original pathogen, are retained for later use. ...
