BIOL 2900 Lecture Notes - Lecture 8: Clonal Selection, Fc Receptor, Antigen
Document Summary
Immunological memory: the ability of the immune system to respond more quickly and effectively to pathogens that have been encountered previously, the primary immune response, primary immune response takes several days, via clonal selection, produces effector and memory cells, the secondary immune response, the same antigen is encountered again, initiated from memory cells. Immunological memory: ability of the immune system to respond more quickly and effectively to pathogens that have been encountered previously, the primary immune response takes several days to produce effector cells (igm cells) via clonal selection, clonal selection produces also memory cells from the best antibody cells (igg binds better), which can last decades in the lymph nodes, the secondary immune response can be developed when the same antigen is encountered again, initiated much faster due to the presence of memory cells, that"s why vaccinations work, in a new infection the memory cells immediately become plasma cells secreting antibodies.
